What is CV-22B Osprey Aircraft?

About CV-22B Osprey

• It is a tiltrotor aircraft that combines the vertical takeoff, hover, and vertical landing qualities of a helicopter with the long-range, fuel efficiency, and speed characteristics of a turboprop aircraft.
• It was developed to fulfill the needs of the U.S. Marine Corps, U.S. Air Force and U.S. Navy operational requirements worldwide.
• It is built by Boeing, an American aerospace company.
• It is used for a wide-range of missions, including long-range infiltration, exfiltration, medium-range assault, special operations, VIP transport, resupply, disaster relief, search-and-rescue, medical evacuation, and humanitarian missions
• Features:
  • It is a multi-engine, dual-piloted, self-deployable, medium-lift aircraft.
  • With its rotors in a vertical position, it can take off, land, and hover like a helicopter. Once airborne, it can convert to a turboprop airplane capable of high-speed, high-altitude flight.
  • It is equipped with dual Rolls-Royce Liberty AE1107C engines.
  • Up to 24 personnel can sit inside the aircraft.
  • It travels nearly twice as fast as most average helicopters.
  • It is equipped with integrated threat countermeasures, terrain-following radar, a forward-looking infrared sensor, and other systems that allow it to operate in various adverse conditions.

Q1) What is a turboprop aircraft?

A turboprop aircraft uses a turbo-prop engine rather than a piston-powered engine or a jet engine. They have one or more gas-turbine engines connected to a gearbox that turns the propeller(s) to move the aircraft on the ground and through the air. Turboprop aircraft have lower operating costs than jets because they burn less fuel, but they are also slower than jets.
