The Boeing V-22 Osprey is a multi-mission military tilt rotor aircraft.

It is takes-off and lands vertically like a helicopter, while it's cruise speed is similar to propelled aircraft.

The Osprey is seen as a replacement for the helicopter with the Marine Corps.

The Osprey is powered by two Rolls-Royce AE Liberty turbo shaft engines.

What is V-22 Osprey?

Emergence of V-22 Osprey

The Bell Boeing V-22 made it's first flight in 1989.

It has a crew of two and can accommodate 24 troops.

The US Marine Corps first took the initiative of such aircraft.

The V-22 Osprey can operate from ships as well as small airfields.

STRUCTURE OF V-22 OSPREY

TECHNICAL BUDGET

The V-22's development budget was first planned for $2.5

billion in 1986, then increased to a projected $30 billion in

1988.

As of 2008, $27 billion had been spent on the Osprey program

and another $27.2 billion will be required to complete planned

production numbers by the end of the program.

APPLICATIONS

It's primary task is to conduct long-range special missions and

combat rescue.

This aircraft is intended foe search and rescue missions and for

delivering and extracting special forces troops.

ADVANTAGES

The Osprey is the world's first production tilt rotor aircraft, with

one three-bladed prop rotor, turboprop engine, and transmission

nacelle mounted on each wingtip.

For takeoff and landing, it typically operates as a helicopter

with the nacelles vertical and rotors horizontal.

The nacelles rotate forward 90° in as little as 12 seconds for

horizontal flight, converting the V-22 to a more fuel-efficient,

higher-speed turboprop airplane.

DISADVANTAGES

The V-22's production costs are considerably greater than for helicopters with equivalent capability, which has a greater payload and an ability to carry heavy equipment the V-22 cannot... an Osprey unit would cost around $60 million to produce.

Between 2008 and 2011, the estimated lifetime cost for maintaining the V-22 fleet grew by 61 percent, mostly from increased maintenance and support costs.

FUTURE SCOPE/DEVELOPMENTS

The US marine corps are trying to make v-22 to take off from sea as well as float in it by replacing it’s landing gear.
