lepe su slicice , video sam ovakav slican model verowatno je ovo neki novi model sa poboljsanjima

nisam odusevljen

USAF takes delivery of first combat-configured Bell Boeing CV-22 Osprey
Flight

The US Air Force took delivery earlier this week of its first combat-configured CV-22 Osprey tiltrotor from Bell/Boeing in a ceremony at the Bell Helicopter manufacturing facility in Amarillo, Texas.

The aircraft handed over was the first full USAF special operations Block B10 configuration and is due to enter active service in 2009. Earlier versions of the V-22 are still in use in the test programme.

Receiving the aircraft was Lt Col Jim Cardoso, commanding officer of the 71st Special Operations Squadron, which will use the Osprey for crew training at its Kirtland AFB in New Mexico.

The USAF has ordered 50 CV-22s, which will be used for long-range infiltration missions for special forces personnel.
Maj Gen Donald Wurster, vice commander of the Air Force Special Operations Command says the aircraft represents "the single most significant transformation of Air Force special operations since the introduction of the helicopter". "Nearly every mission we have faced in the last 20 years could have been done better and faster with the V-22," he says.

The CV-22 has around 85% commonality with the Maritime version MV-22 Osprey that the US Marine Corps will use from 2007. Differences include a multi mode radar with terrain following/terrain avoidance modes allowing nighttime low flying exit missions in unknown territories. The CV-22 also has additional internal fuel capacity and enhanced navigation systems

The US Department of Defense approved full rate production of the Osprey in September last year following the completion of mission test flights for the MV-22. The CV-22 will undergo additional test flights this year.

  dobar je avion bre nezezajte , zbo cega bi ga ukidali ako moze da ima sve opcije kao avion i helikopter

Чуо сам негде да су изузетно тешки за управљање у нормалним условима а камоли у борбеним!?

.....хм за ово незнам али знам за ове потешкоче.....

An Air Force version of the V-22 tilt-rotor Osprey aircraft last week experienced a compressor stall of both engines after flying into a cloud at 18,000 feet, presumably because of icing problems, sources have told the Project On Government Oversight. The aircraft, CV-22 #6, was on a routine flight to Edwards Air Force base in California. It did not recover from the stall until it had descended to warmer air at about 10,000 feet, the sources said.

As a precaution the aircraft landed in Prescott, Arizona.

"This is very disturbing. Only last month the Pentagon approved the Marines version of V-22 for full-rate production," said POGO Senior Defense Investigator Eric Miller. "And now we find out the aircraft can't even fly into a cloud."

Ospery je u slucaju ostecenja bilo kog motora potpuno NEUPRAVLJIV. Bilo koja letelica sa tzv. tilt rotorom (poput ospery-a) je krajnje rizicna i u mirnodopskoj upotrebi, a kamoli u ratnoj. Bilo koji avion u slucaju otkaza motora ima makar male izglede za "spas". Usmeris ga ka zemlji, sakupis rezervu brzine i izvuces u kakvo takvo sletanje. Osper ima jako male uzgonske povrsine tako da ovaj princip ne pomaze. Obican helikopter ima, iako manje u odnosu na avion, sanse da se izvuce. Princip je slican kao na avionu, normalno razlika je u tome posto helikopter nema uzgonske povrsine
obrusavanjem se zbog koraka elise postize veci broj obrtaja glavnog rotora i pri sletanju se to moze iskoristiti za ublazavanje udara.
Osprey je nazalost pokupio i najgore osobine obe vrste letelica. U slucaju bilokakvog pokusaja spasavanja letelice, osperj upada u kovit i cao.
Ako nekoga interesuje kolika je tacnost ovih informacija mogu samo da kazem da sam morao u detalje kroz teoriju i praksu sve da naucim jer sam i ja pilot.
