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:

When mice take the Mickey out of airline…

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.

Brand new drone in China

The V750 is a brand new unmanned helicopter designed by Qingdao Haili. It successfully completed its maiden flight in Shandong province three weeks ago.

This UAV has a load capacity of more than 77 kg. It can reach more than 160 km/h, and it can be remote-controlled from up to 153 kilometers away. The V750 drone could be used for ISR purpose. With a weight of 100 kg, it is deemed to be the largest drone in China as it could be as large as the American MQ-8 “Fire Scout”.
