CHINESE J-31 STEALTH FIGHTER AIRCRAFT

The brand new 5th-generation fighterjet Shenyang J-31 – or F60, which would be nicknamed Gyrfalcon – took off on October 31, 2012. She thus performed a test flight – probably her maiden flight – on Wednesday.

This futuristic PLAAF (People’s Liberation Army Air Force) stealth multirole jetfighter looks like an F-35 Lightning II though the Gyrfalcon (or Falcon Eagle?) turns out to be a twin-engine a/c. She would be more maneuverable but smaller than the latest Chengdu J-20 Black Eagle stealth fighter. Her radar cross section (RCS) might be very small, and stealthier than recent 5th-generation fighter aircraft as the radome mounting looks as if it were – like the rest of the airframe – designed with reentrant shapes.

This fighter aircraft would not exceed Mach 2, and she features a DSI (Diverterless Supersonic Inlet) so that the airspeed can be reduced while entering the air intake, thus preventing the engine from breaking up.

Here are a few pictures, and videos:

Could RAFALE benefit from F-35 glitches?

 

JSF F-35 Lightning II

F-35 Lightning II

The British Harriers were to be replaced by the F-35Cs. Do you remember? You may have learnt from the recent news that the carrier variant of the Lockheed Martin Aeronautics Joint Strike Fighter – CV JSF (Carrier Vessel variant’s Joint Strike Fighter) – F-35C was unable to catch the wire onboard the aircraft carrier during the latest landing tests.

Strange as it may seem, the F-35C’s designers may have not forecast what would unfold during a test flight while landing on an aircraft carrier:

The arresting hook (tailhook) never engaged the arresting wire as the clearance between the tail hook and the main landing gear’s tyre tread is too short for such a speed. An F-35C Lightning II missing her carrier landing has been reported even though some U.S. officials would have dismissed such information which might result from simulated tests.

Added to that is a software bug which had grounded the CV JSF for 6 days a few month earlier for the fifth-generation fighter aircraft might have encountered wing-folding input while flying!

As a result, the British Ministry of Defence might find a Plan-B solution as these design flaws, and some others which date back to November 2011 are deemed unacceptable for such an expensive fighter aircraft – $139.5 million for the F-35C (CATOBAR – Catapult Assisted Take Off But Arrested Recovery), and $150 million for the F-35B (STOVL – Short Take-Off and Vertical Landing). The latter can land on carriers but she is more expensive, and the JSF program costs have already increased several times.

 

Moreover, the JSF would not be able to fire AMRAAM air-to-air missiles as reported in this video:

And there’s even more: according to a Pentagon study team report, 13 areas of concern that remained to be addressed in the F-35 would have been identified. For instance, the Helmet Mounted Display System (HMDS) would not work properly…

The British MoD is therefore considering the purchase of either F/A-18E Super Hornets or RAFALEs for the RAF. The French Dassault which has already lost the Swiss NAC tender due to replace the Swiss Air Force’s F-5s, would be proposing a new offer with 18 RAFALEs at a cost deemed lower than the 22 SAAB Gripens’ one according to the Swiss press.

The RAFALE is still in competition with the Eurofighter in the Indian MMRCA tender. the Indian officials are expected to make a decision this week. To be continued… ==> We have just learnt (on January 31, 2012) that the RAFALE has won the MMRCA tender… :-)

U.S. drone captured in Iran

The USAF RQ-170 Sentinel – ISR (Intelligence Surveillance and Reconnaissance) + Ground-attack stealth drone – recently captured in Iran should remain indefinitely according to the latest news:

“No one returns the symbol of aggression to the party that sought secret and vital intelligence related to the national security of a country,” Iranian General Hossein Salami said.

Nothing more was revealed but the U.S. Air Force admitted that the UAV would have had a malfunction on its course to Iran after leaving Afghanistan. The pictures of the fuselage cannot show evidence of shooting down, and nothing proves what the Iranian officials suggested about EW (Electronic Warfare) means which might have brought down the drone to the ground perhaps by jamming.

PEARL HARBOR ATTACK & WWII

The Pearl Harbor Attack(called Hawaii Operation or Operation AI by the Japanese Imperial General Headquarters – Operation Z in planning – and the Battle of Pearl Harbor) happened on Sunday December 7, 1941 ie 70 years ago. Here is a video of remembrance of the infamous day which dragged the United States of America into World War II:

When mice take the Mickey out of airline…

Mouse in commercial aircraft

It first happened on Monday September 5, 2011. A Nepal Airlines flight was cancelled at Tribhuvan International Airport, Kathmandu.

Do you guess why? The flight attendants spotted a stowaway mouse onboard their B-757 bound to Bangkok! The small rodent fled from the galley’s pantry, and rushed from a box of drinks to the back of the cabin although the 113 passengers did not notice the tiny stowaway.

The mouse was finally caught thanks to a glue trap. The jetliner was grounded for more than eleven hours.

 

Then, the same Boeing 757 – this time bound to Kathmandu – was grounded at Hong Kong International Airport on Tuesday September 6, in the evening.

The reason: the pilots spotted a mouse in the cockpit just before the airplane departure. The aircraft has not been cleared to take off because this mouse was trapped but then escaped, and would still be on the loose. The 84 passengers were rerouted on a Dragonair aircraft.

 

As far as flight safety is concerned, an aircraft cannot take off with a mouse moving freely onboard as it can gnaw the wiring, and therefore represents a potentiel danger.

It can only be caught or trapped. However, NAC (Nepal Airlines Corporation) could not poison any mouse for a small animal can damage an airplane even if it is dead somewhere, and particularly if in contact with a vital part of the plane.

 

Special thanks to Mr Hermas, and LadyEleanorA who buzzed this piece of news.
