The document discusses the V-22 Osprey, a military tiltrotor aircraft that can take off and land vertically like a helicopter but also fly faster than conventional helicopters. It emerged in 1989 and entered service in 2005. Key facts are that it has a crew of 2-4, can carry 24 troops, and is powered by two Rolls-Royce engines. While costly, it provides advantages over helicopters through its ability to operate from ships and airfields and conduct long-range missions. Future developments may enable it to take off from sea and float.

3. What is V-22 Osprey?
 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.

4. 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.

10. 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.

11. 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.

12. 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.

13. 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.

14. 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.
