The chilling crash video of National Air Cargo 747 at Baghram Air Base ....that happened yesterday:
That will make a perfect video reference point of what happens when you get the aircraft into a stall. First the post-stall, then left wing stops flying, then the roll over and finally total loss of control. It didn't look like he had sufficient forward velocity, and pitch exceeded by a few degrees too much on his V2climb out. RIP to the crew.

According to some articles, it was carrying military vehicles weighing around 70 tons. Cargo came loose and aircraft became tail heavy. Stalled and crashed. Don't know how authentic that bit is. But if true, the aircraft was impossible to recover once it became airborne.

The final flight of the X-51A Waverider test program has accomplished a breakthrough in the development of flight reaching Mach 5.1 over the Pacific Ocean on May 1


The X-51A is unique primarily due to its use of a hydrocarbon fuel in its supersonic combustion ramjet, or Scramjet, engine. Other vehicles have achieved hypersonic - generally defined as speeds above Mach 5 - flight with the use of hydrogen fuel. Without any moving parts, hydrocarbon fuel is injected into the scramjet's combustion chamber where it mixes with the air rushing through the chamber and is ignited in a process likened to lighting a match in a hurricane.

The use of logistically supportable hydrocarbon fuel is widely considered vital for the practical application of hypersonic flight.

As a technology demonstration program, there is no immediate successor to the X-51A program. However, the Air Force will continue hypersonic research and the successes of the X-51A will pay dividends to the High Speed Strike Weapon program currently in its early formation phase with AFRL.

SoKo has its own Light Fighter Program FA-50

Check the video http://www.youtube.com/watch?v=Zs5BRkc6Zdo

Korea Aerospace Industries Ltd (KAI) has won a 1.12-trillion-won ($1.02 billion) order to supply an unspecified number of FA-50 fighter jets to South Korea's military through the Defense Acquisition Program Administration (DAPA), Reuters reported. The contract is based on an initial mass-production agreement reached in December 2011, the South Korean aircraft maker said in a regulatory filing on Tuesday. The contract will run until October 2016.

Hungary re-releases decomissioned MiG-29 sale tender

link

The Defence Ministry has again invited a single-round open tender for the sale of 24 decommissioned Mig-29 fighter planes, daily Népszabadság said on Friday. The deadline for submitting bids for 18 Mig-29B and six Mig-29UB aircraft, as well as 21 RD-33 replacement engines is June 14. A minimum purchase price has not been specified in the tender but, if successful, it is expected to yield HUF 9.8 billion, the paper said. An earlier tender for the sale of eight Mig-29 aircraft produced eight bids, but none were valid. The Hungarian Air Force got 28 MiG-29s from Russia in 1993, as a partial repayment of government debt. The MiG-29s have been phased out and replaced with Swedish-made Gripens.


I'm once again hoping that the IAF picks these up at very cheap prices, puts them through the MiG-29UPG upgrade and then gets another squadron of MiG-29UPG fighters up and operational in quick time. It'll be the most cost-effective solution for adding another squadron of multi-role fighters.

That's 'cause they have yet to get their sci-fi Darth-Vaderesque HMDS working without the glitches so they have to make do with 4th gen HUD... :twisted: :twisted:

Alenia Aermacchi pilots eject from stricken M-346 Master trainer aircraft. This is the second M-346 crash so far.

link

Alenia Aermacchi says one of its test pilots is in a good condition after being forced to eject from a prototype M-346 advanced jet trainer on 11 May.

In a statement, the company says the twin-engined aircraft - which it identifies as CMX617 - encountered a technical problem around 20min after taking off from Turin-Caselle airport. "The aircraft crashed in Val Bormida, between the provinces of Cuneo and Savona, without damage to people or properties," after its lone pilot ejected successfully, it adds.

Further details about the crash have yet to be disclosed, but Alenia Aermacchi says it has formed an internal technical commission to investigate the factors leading to the accident.

The incident represents the second loss of an M-346 prototype, with another example having crashed off the coast of Dubai following an air show appearance in 2011. Both crew members survived after ejecting from their Honeywell F124-200-powered aircraft.

Alenia Aermacchi has so far delivered two T-346A trainers to the Italian air force for test and evaluation purposees, with the service to receive four more under a launch order for the type. Export successes have also already been scored, with the Republic of Singapore Air Force and Israeli air force to receive 12 and 30 examples, respectively.

NRL Shatters Endurance Record for Small Electric UAV
Researchers at the U.S. Naval Research Laboratory flew their fuel cell powered Ion Tiger UAV for 48 hours and 1 minute on April 16-18 by using liquid hydrogen fuel in a new, NRL-developed, cryogenic fuel storage tank and delivery system. This flight shatters their previous record of 26 hours and 2 minutes set in 2009 using the same vehicle, but with gaseous hydrogen stored at 5000 psi.
...



Something on the lines I hope, NAL / DRDO is doing something about... :idea: :idea:

The real achievement by NRL is not the sound signature of the UAV.

The real achievement is the development of a compact light weight cryogenic tank and the use of hydrogen fuel cells in a UAV.

Cost wise, hydrogen fuel cells are extremely expensive. And the cost of cryogenic storage and liquifying Hydrogen in the first place is another expensive proposition and not likely to be deployed on the battlefield anytime soon. This technology is unlikely to go mainstream anytime soon but it does advance utility of Hydrogen fuel cells.

with the X47 B probably ready for IOC service in 5 yrs, it would be able to take over a lot of strike missions, leaving the F-18 free to use its big motors and radar for the air to air playground.

it might affect the F-35C CTOL purchase numbers.

atleast the F-35A has a guaranteed market to replace the huge nos of F-16 and F-15 nearing retirement worldwide over next two decades.

F-35 to achieve IOC in 2016, even while new F-35s are rolling off the assembly line and testing continues. I hoped for such a thing to happen with the Tejas as well, but the IAF is not the USAF.

link


WASHINGTON (Reuters) - The U.S. Air Force plans to start operational use of Lockheed Martin Corp.-built F-35 fighter jets in mid-2016, a year earlier than planned, using a similar software package as the Marine Corps, two sources familiar with the plans said on Monday.

The Air Force's decision to accelerate its introduction with a slightly less capable version of the F-35 software package means the planes will carry fewer weapons at first, although the software will later be upgraded to the final version,
said the sources, who were not authorized to speak publicly.

Air Force spokeswoman Ann Stefanek said a final decision had not been made and declined to comment further. A spokesman for the Pentagon's F-35 program office declined to comment.

The decision reflects the military's desire to start using the new warplanes, which are already rolling off the assembly line at Lockheed's sprawling Fort Worth, Texas, plant, even as military officials continue to test the plane.


"This decision gets that (U.S.) fifth-generation capability out on the front lines that much sooner," said one of the sources familiar with the Air Force's plans. "It also sends a message about confidence in the program to Congress and the international partners."

Former Air Force Secretary Michael Wynne said accelerating operational use of the new warplane would allow the Air Force to learn more about the F-35's integrated battle management system.

"This is not just about replacing aging F-15's or F-16's; it is about changing the order of battle and truly embracing a integrated form of warfare where the F-35 manages the targeting and directs supporting fire at the same time as providing more precise aim points," Wynne told Reuters in an email.

The Air Force, Marines and Navy must report to Congress by June 1 on their target dates for initial operational capability, or IOC, which marks the point when the services have enough planes on hand to go to war if needed. Actual deployments usually lag IOC dates by about a year.

The sources said the services would send Congress a list of target or "objective" dates for declaring initial operational capability and a list of "threshold" dates, or deadlines.

The Marines Corps is sticking to its plan to begin early operational use in mid-2015 of its F-35B jets, which can take off and land like a helicopter. It will be the first of the three U.S. military services to start using the jets.

Its threshold is the end of 2015. The planes will run the F-35's 2B software, which will give the Marines an initial war fighting capability that includes some air-to-air skills, the ability to strike targets on the ground and carry several internal weapons, including laser-guided bombs.

Lockheed on Monday said one of its F-35 B-model planes completed the first-ever vertical takeoff on May 10, demonstrating a capability needed for repositioning jets in areas where they cannot perform a short takeoff.

The Navy has set mid-2018 for starting operational use of its C-model F-35, which is designed for use aboard U.S. aircraft carriers. Its deadline or threshold date is early 2019.

The Air Force decision marks a reversal from its earlier insistence that it needed the final 3F software package and comes after a Pentagon report cited China's development of two new fifth generation fighters over the past year.

The Air Force began studying the possible change several months ago. Lieutenant General Charles Davis told reporters in March that it might make sense to declare initial operating capability earlier than initially planned, given that the weapons on board would be suitable for basic war fighting needs.


The Air Force will have about 100 F-35s by 2016, when it plans to declare the planes ready for operational use.

The Pentagon's program chief, Lieutenant General Christopher Bogdan, told lawmakers last month he was "moderately confident" that the 2B software -- and the associated 3I software being developed for international buyers -- would be completed in time for the planned Marine Corps IOC in mid-2015.

The Air Force jets would use the 3I software, which will include a technology refresh with improved memory processors for some sensors on board.

Bogdan said it was not as clear that work on the final software package would be done in 2017, when the Air Force initially planned to declare IOC.

The final 3F software will support use of the aircraft's full war fighting capability, with additional internal and external weapons, and more advanced air-to-air and air-to-ground capabilities.

moment Cheen became our biggest warfighter threat the whole ballgame has shifted.

small fry like gripen, tejas, m2k, mig29, f16 are at best suitable now for CAPs and CAS. the major chinese bases in lanzhou and chengdu areas are like 500+km from our bases , with more in the back. the major chinese economic targets are like 1000km away.

sorry, but none of the above are suitable to deliver any useful payload even if loaded to the gills with drop tanks and escorted all the way.

they can be the linebackers but not the wide runners to the take the fight to the enemy. are we always going to be in defensive mode, cowering in our white dhotis and trying to defend tawang or demchok desperately?

grow up boys! there are only a few platforms capable of taking the fight deep into tibet and china....what bells and whistles fitted can differ but nothing can compensate for a wrong sized platform.

strike eagle, su30, su35bm, rafale (albeit with CFT and 2 huge drop tanks slowing down).....someday pakfa and pakda.

and with the ever present threat of SRBMs and GLCMs bases might need to move deeper into interior to permit adequate warning time...again range issue comes into play and hugely expensive tanker support to be laid on just to remain functional over the battle area.

if the J20 turns out capable of supercruise and long range(given its huge size) could be a real problem for short range CAP birds to tag-n-bag that one, esp if it unleashes a shower of gliding or powered munitions from 50km out before decamping. effecting a T-shaped intercept against a Mach1.3 supercruiser flying at 45,000ft could be costly in fuel and endurance for CAP birds.

we need something like meteor/jdraam and big aperture aesa radars to level the playing field against these next gen of (V)LO fast movers and LO long range ground attack missiles. and here we are still stumbling along trying to IOC the Astra mk1 after donkeys years.

a lot of people should be more scared than they look, or maybe they are scared but not showing it.

South Korea Nears F-X Phase 3 DecisionSouth Korea Nears F-X Phase 3 Decision[/url]

“Our neighbors are upgrading their fighter technology, so we must do so, too,” says one government official. A second official, with deep insight into the country's defense requirements, goes further: The 60 Boeing F-15Ks that South Korea has from the F-X Phase 1 and 2 programs last decade already offer enough aerial strike power for dealing with North Korea. While more big fighters would be useful if war on the peninsula broke out, the real point of the Phase 3 competition is that Japan is buying Lockheed Martin F-35As, China is developing the J-20, and Russia is working on the Sukhoi T-50 (PAK FA), says that official. Even in F-X Phases 1 and 2, North Korea was considered only part of the problem, he adds.

That is why South Korea's Defense Acquisition Program Agency is giving equal importance to air-to-air and strike missions in F-X Phase 3, even though defeating North Korea's modest fighter force would hardly be a challenge. Slightly contradicting that, an F-X Phase 3 program official told Aviation Week two years ago that excellent strike capability was valued above excellent air-to-air capability. Still, the difference in weight given to the two capabilities is evidently not great.
