IAF may order 70 basic trainers made by HAL

Written by Thursday, 28 September 2017 08:47

The HTT-40 is currently undergoing a string of elaborate tests at HAL to demonstrate that it is safe for rookie pilots and meets IAF’s exacting standards for trainer planes. Test pilots have wrapped up intensive flight tests but some brutal trials are yet to be conducted, said a second official.

The Indian Air Force (IAF) plans to start the official process within three months for the possible purchase of 70 locally produced basic trainers from state-owned aircraft maker Hindustan Aeronautics Limited (HAL), three senior IAF officers said on condition of anonymity.

IAF is set to send a request for proposal (RFP) to HAL for the indigenous Hindustan Turbo Trainer-40 (HTT-40) before the end of the year, they added.

“The HTT-40 has entered the final stages of rigourous testing. The air force is optimistic that the trainer will meet its requirements. If all goes well, the RFP will be out by the year-end,” said one of the officials cited above who asked not to be named.

The HTT-40 is currently undergoing a string of elaborate tests at HAL to demonstrate that it is safe for rookie pilots and meets IAF’s exacting standards for trainer planes. Test pilots have wrapped up intensive flight tests but some brutal trials are yet to be conducted, said a second official.

A few days ago, the aircraft successfully completed the six-turn spin (towards the right), recovering from an uncontrolled flight using conventional methods. “The next stage of trials will be critical as it involves testing the HTT-40’s spin behaviour in the left direction, which is far more complicated,” the second official said.

If the remaining tests go smoothly, HAL could begin production by early 2021, said a third official tracking the air force’s modernisation drive. IAF, however, is clear that it does not want a piecemeal delivery of the basic trainers. “We don’t want HAL to deliver the aircraft in ones and twos as that will not meet our training requirements. We would need at least 20 planes to begin training. According to our estimates, it will take HAL around four years to deliver that number,” the third official added.

To facilitate the release of the RFP this year, IAF plans to seek a fresh Acceptance of Necessity (AoN) from the defence acquisition council to pursue the HTT-40 purchase under the Defence Procurement Procedure (DPP) 2016 instead of DPP-2008, which currently covers it. “That’s important because under DPP-2008, user trials have to be conducted before the RFP is issued. However, the provisions of DPP-2016 allow the RFP to come before the user trials,” said the second official cited above.

The upcoming RFP may also allow HAL to release around $25 million to upgrade the Honeywell TPE331-12B turboprop engine that powers the basic trainer to extract maximum performance from the aircraft, said the first official. HAL was reluctant to spend on the upgrade unless the order came through.

Rookie pilots in IAF go through a three-stage training involving the Pilatus PC-7 MkII planes, Kiran trainers and finally the Hawk advanced jet trainers before they can fly fighter jets. As the Kirans are approaching the end of their service life, some amount of Stage 2 training is being done on the PC-7.

The defence ministry in July suspended business dealings with Pilatus Aircraft Limited for one year for violation of a pre-contract integrity pact in a ~2,900-crore contract for 75 basic trainers, and also factoring in ongoing Indian investigations against the Swiss plane maker for alleged corruption and irregularities.

The contract included a follow-on purchase of 38 more planes, but the ban means IAF can’t invoke the clause. The order for additional planes could be sourced from HAL, said a fourth IAF official. Experts welcomed IAF’s decision to take the HTT-40 purchase forward. “It’s a big thumps up to indigenisation and the RFP is an indicator that the locally made trainer will meet IAF’s requirements. It is now up to HAL to meet the timelines and provide adequate technical support. It has been found wanting in some of those aspects in the past,” said Air Vice Marshal Manmohan Bahadur (retd), additional director general, Centre for Air Power Studies. Source : ht

On September 7, Lander Vikram, with rover Pragyan, lost contact with the ground station during its final descent, just 2.1 kms above the lunar surface, minutes before the planned touch-down on the Moon.

As the Lunar night starts to fall early Saturday, hopes of re-establishing communication with India’s moon mission Chandrayaan-2’s Vikram lander seems to be all but over with its 14-day mission life about to end.

On September 7, Lander Vikram, with rover Pragyan, lost contact with the ground station during its final descent, just 2.1 kms above the lunar surface, minutes before the planned touch-down on the Moon.

A former official of the Indian Space Research Organisation (ISRO) suggested that keeping the technology simple; freezing the mission profile and not changing it till the last moment; carrying out the simulation tests to the maximum possible level -- are some of the learnings from the crash landing of India’s moon lander Vikram.

Speaking to IANS, the official said, “Space technology itself is complicated and one should not add more complications to it as it had happened with the lander Vikram. For instance, the four throttleable engines to work in unison is a technical challenge. Then there is the fifth engine at the centre.”

According to the ex-official, had it been known earlier that the GSLV-Mk III (Geosynchronous Satellite Launch Vehicle) rocket was available for the mission, the spacecraft could have been designed with a powerful single engine, and not with five engines.

“Ideally a moon lander of this kind should have a single 3,500 Newton (N) engine. This would have obviated the complexities of managing the four throttleable engines working in union. Other nations had used a powerful single engine while landing their crafts on the moon. Before the touchdown on the lunar surface, the single engine would be cut off and the lander would have made a soft landing,” he said.

According to him, the mission profile underwent last minute changes and varied from the original plan.

“Originally the plan was to launch the Chandrayaan-2 spacecraft along with the lander using GSLV-Mk II that can carry a weight of two tonne,” he said.

After a while, the fifth engine was added at the centre of the lander in order to prevent the dust from the Moon surface from damaging the lander while it attempts to land, he added.

“This in turn increased the spacecraft’s weight and changed the other specifications that GSLV-Mk II was not capable of carrying. It was then decided to launch Chandrayaan-2 with higher capacity GSLV-Mk III,” he further added.

Originally, the idea was to switch off all the four throttleable engines first and allow the lander to slowly drop down. “The idea was to allow the lander to drop down from a height of 10 metres at 2 metres per second,” he added.

“After the fifth engine was introduced, there was a software change. How well it was tested is not known,” he said.

“The ISRO has to simulate various things and scenarios with the data on hand. It should also check and simulate what were the actions that were not done and the results that they had assumed,” another retired official, who preferred to remain anonymous, told IANS.

According to him, ISRO has to see whether any simulation prior to the launch was overlooked or waived any known deviation.

“ISRO should also check out the extent to which various failure modes were simulated. ISRO has to go into these details. It would take considerable time to arrive at a conclusion,” he added.

Space experts had told IANS that in case of data loss, it is assumed that the satellite suddenly changed its altitude. If the target/satellite experiences a large angular rotation, the communication link usually breaks.

According to them,the reason behind the lost communication link could be the wrong input being loaded on to the lander.

In other words, the loss of communication link with Vikram could be due to sudden disturbances -- in the form of engine propulsion or wrong data input, experts said.

The Vikram was designed to land on the lunar surface on its four legs at a speed of about 7 km per hour. But due to a few complications faced by the lander minutes before the touch-down, the Vikram might have hit the Moon’s surface at much higher speed than expected.

“The Vikram’s maximum tolerance landing level was 5 metres per second. But it seems during its final moments the landing speed was very high,” the retired official added.

“In the case of Vikram’s landing what was its point of no return -the point where its descent cannot be stopped or changed or what was the lowest or nearest point from the lunar surface that the lander could have been manipulated is not known,” he said.

Former ISRO officials said the Indian space agency would have got various engineering data from this mission which will be useful for the future course of action. Also adding, “There should be Plan B if something goes wrong with Vikram and whether it was activated is also not known.”

Originally scheduled for July 15, Chandrayaan 2’s launch was aborted due to a technical snag at the eleventh hour before take-off. After fixing the problem in about a week, India’s second lunar mission was launched from Sriharikota on board the GSLV Mk III on July 22 at 2.43 pm.

India’s second Moon mission has cost less than half the budget of Hollywood blockbuster ‘Avengers Endgame’. The total cost of the Chandrayaan 2 mission is estimated at 124 million US dollars, which includes 31 million US dollars for the launch and 93 million US dollars for the satellite. Source : ht

Looking to upgrade to the latest Galaxy S9 series? Read on to get a clearer idea.

Samsung recently launched its flagship smartphones, Galaxy S9 and Galaxy S9+ in India. There has beeb a lot of buzz around the Galaxy S9 series particularly its camera features. The smartphones also come with incremental upgrades over its predecessors, Galaxy S8 and Galaxy S8+. However the question that remains among users is if they should upgrade from their existing Galaxy S8 series to the Galaxy S9.

Other than the new camera features and upgrades under the hood, the Galaxy S9 series doesn’t have much to offer over the Galaxy S8 duo. However, users with the older Galaxy S7 and S6 series can definitely go for this upgrade. Here’s a look at the differences between the two flagship generations for a better idea.

Display, Design

Samsung didn’t make any major changes with the Galaxy S9 duo considering the major redesign the Galaxy S8 series went through last year. One small but important change however is the placement of the fingerprint sensor which is now below the camera lens and not beside it.

The display size on both Galaxy S9 and Galaxy S9+ remain the same with curved AMOLED Infinity Display and 18:9 aspect ratio. The Galaxy S9 features a 5.8-inch display, and the Galaxy S9+ has a bigger 6.2-inch screen.

Processor, RAM and Storage

It’s common knowledge that Samsung is the first to launch its smartphones with the latest Qualcomm processor. The Galaxy S9 series is powered by Qualcomm’s Snapdragon 845 processor. This variant is however restricted to the US market. Global markets will get the Exynos 9810 processor model which is also the latest in-house chipset.

In comparison, Samsung Galaxy S8 series runs Snapdragon 835 and Exynos 8895 processors under its hood.

While the RAM capacity remains the same, Samsung beefed up the storage on Galaxy S9+ along with microSD support up to 400GB. Galaxy S9 comes with 4GB RAM and two storage options of 64GB and 256GB. The older Galaxy S8 is available with 4GB RAM and 64GB storage and microSD support up to 256GB.

The top model gets the same treatment with 6GB RAM plus 64GB and 256GB storage options. Galaxy S8+ has the same RAM capacity but with 64GB and 128GB storage options.

Camera

Samsung prides on the camera features of the Galaxy S9 series. The biggest upgrade here is the dual-camera setup on the Galaxy S9+ which is a combination of 12-megapixel and 13-megapixel sensors. Galaxy S9 sports a single 12-megapixel rear camera. Up front, both smartphones house an 8-megapixel camera for selfies.

The specifics are the same as the Galaxy S8 duo also feature a 12-megapixel rear and 8-megapixel front camera.

However, the cameras on Galaxy S9 and Galaxy S9+ come with dual-aperture mode which switches between f/1.5 and f/2.4 according to the lighting conditions. There’s also a super slo-mo feature which records videos at 960 frames per second. Lastly, the smartphones offer an iPhone X Animoji-like AR emoji feature.

Battery, OS and connectivity

Both the Galaxy S8 and Galaxy S9 series have the same battery capacity of 3,000mAh and 3,500mAh. Galaxy S9 and S9+ run the latest Android 8.0 Oreo, while the Galaxy S8 series ship with Android 7.0 Nougat. Samsung is expected to roll out Android 8.0 Oreo for the Galaxy S8 smartphones but the release has been facing delays.

The connectivity options also remain the same with dual-SIM support, Bluetooth 5.0, Wi-Fi, USB Type-C port and 3.5mm audio jack. The latest Galaxy S9 duo however comes with Gigabit LTE for 5G connectivity.

Price

Samsung Galaxy S9 starts at Rs 57,900 for the base variant with 4GB RAM plus 64GB storage, while the top model with 256GB storage will retail at Rs 65,900. Galaxy S8, on the other hand with 4GB RAM and 64GB storage is available at Rs 53,900.

Galaxy S9+ with 4GB RAM and 64GB storage is priced at Rs 64,900, and with 256GB storage the price tag is Rs 72,000. The base model of Galaxy S8+ with 4GB RAM plus 64GB storage is priced at Rs 58,900, and with 6GB RAM plus 64GB storage it is available at Rs 64,900. Source : ht

WhatsApp Co-Founder Brian Acton to Leave Company

Written by Wednesday, 13 September 2017 06:18

 

Brian Acton, co-founder of WhatsApp, now owned by Facebook, will leave the messaging service company to start a new foundation, he said in a Facebook post on Tuesday.

Acton spent eight years with WhatsApp, which Facebook bought in 2014 for $19 billion in cash and stock.

A Stanford alumnus, Acton co-founded WhatsApp with Ukrainian immigrant Jan Koum in 2009. The duo worked at Yahoo before starting WhatsApp.

Here's Acton's Facebook post announcing his departure from WhatsApp, and explaining his reasons, in its entirety.

"After 8 years at WhatsApp, I have decided to move on and start a new chapter in my life.

I am very fortunate at my age to have the flexibility to take new risks and focus on what I'm passionate about. I've decided to start a non-profit focused at the intersection of nonprofit, technology and communications. It's something I've thought about for a while, and now it's time to just focus and execute. I'll have more to share in the coming months.

This decision is, of course, a tough one. I'm proud of what our team has accomplished in only a few years, and it's humbling to see that so many people rely on WhatsApp every day.

Micro-blogging website Twitter is reportedly testing a feature that will simplify the way users post "tweetstorms" — a series of related tweets posted by a user in quick succession.

According to a report on Engadget on Monday, A user has discovered a hidden, experimental "tweetstorm" feature in Twitter's Android app that simplifies the process. "Instead of posting tweets one at a time and replying to them in sequence, you compose everything behind the scenes and share it all at once," the report added.

Hidden inside the Android app is a way to write a "tweetstorm" and see it broken into distinct tweets and then tweet them all at once.

Twitter, however, declined to comment on the feature which is yet to be made available to the public.

Twitter has lifted the 140-character limit for its 328 million-plus users to send direct messages. While Twitter is largely a public experience, direct messages let you have private conversations about the memes and news that unfold on the micro blogging site. The company said last year that it would stop counting photos, videos and GIF animations toward the 140-character limit.

This report comes a day after Twitter started allowing users to share access to multiple accounts via iOS and Android applications without needing to share that account's password.

WhatsApp rolls out two new feature for both Android and iOS users. One of them is the Picture-in-Picture video calling feature and the second one is the text status update. To recall, both the features were earlier available for the beta users, but now WhatsApp has pushed out both the features to stable builds. WhatsApp has been rolling to several new features almost every other day; this is basically because the Facebook-owned messaging platform is aiming towards improving its functionalities.

The new Picture-in-Picture video calling feature allow users to multitask. The feature basically allows the users to make video calls and send messages to friends simultaneously. For instance, if a user is on a video call and also wants to talk to some other friend via message, they can simply resize the video calling screen so they can talk to one friend via video call, and message the other one. After resizing the video call screen will appear at one side of the mobile screen, while the background will be that of the chat box. It is noteworthy, the resized video calling screen can be resized as per requirement and it can also be dragged to any corner of the phone screen.

This is the Picture-in-Picture feature, also known as PiP. Now the text status updates feature. Like we share pictures and videos as status, iOS and Android users will now be able to set a text status as well. It is different from the profile text status. We know that picture and videos on WhatsApp status last's only for 24 hours. The scene will be the same with the new WhatsApp text status as well. So, how does this feature work?
