US Marine Corps grounds all 46 MV-22 Osprey tiltrotors after flight control issue
By Justin Wastnage

All 46 of the US Marine Corps’ Bell Boeing MV-22 Osprey tiltrotor vertical/short takeoff and landing aircraft have been temporarily grounded after an cold-weather check identified a computer chip redundancy fault in the flight control systems.

Each Osprey is triple redundant, but extreme weather trials on the aircraft, the USMC found computer chips that provide back-up on the flight control system could fail to perform as required in this specific role.  "Built-in test procedures in the flight control computer (FCC) that are performed before flight detected the failure; this failure mode has not occurred in flight," the Corps says.

"Engineering analysis of the issue is continuing and FCCs are being removed and inspected to isolate the fault-producing chip," the Marines add. FCCs with the fault-producing chip will be fixed, and unaffected FCCs will be returned to aircraft, allowing all aircraft to return to flight, the Corps says in a statement.!!!

bolje sada nego onda izvini......!!!!!!!!

Ovi tilt-rotori stalno imaju nekih problema, steta, posto je to jako interesantan koncept. Negde sam citao da mu marinci traze zamenu, ali ne znam sta bi to podrazumevalo, pretpostavljam nesto sto radi na slicnom principu.

Boeing i Bell razrađuju koncepte tilt-rotora...

Bell and Boeing have studied larger Quad Tiltrotor (QTR) military models for possible application to the US Army's Joint Heavy Lift (JHL) program. A Quad Tiltrotor is a larger four rotor version of a Tiltrotor aircraft. It has 2 sets of fixed wings and 4 tilting rotors mounted at the tips of the wings. The program has been nicknamed the V-44 Tiltrotor for the four Tiltrotor version and V-66 Tiltrotor for the six tiltrotor version. These poly-tiltrotor aircraft have also been called "The Flying Freight Train" for their large capacity almost the size of a railcar. These may carry as many as 100 passengers or troops or heavy cargo over 50,000 pounds. They would use uprated versions of the tiltrotor engines used for the V-22 Osprey. These designs have been seen in Popular Science and Popular Mechanics.
