V-22 Osprey

The V-22 Osprey, produced by Bell Helicopter along with Boeing Defense, is a military transport aircraft used primarily by the U.S. Marine Corps, U.S. Air Force, and U.S. Navy. It is capable of the vertical performance of helicopters, including hover, with the flight speeds and ceiling of fixed wing aircraft. The V-22 Osprey can be specifically configured for its missions such as special operations, search and rescue, or assault.

V-22 Osprey aircraft are capable of air-to-air refueling, provide special warfare and fleet logistics support, combat transport, and are used in search and rescue operations. They have folding rotors and rotating wings to facilitate storage aboard assault ships and aircraft carriers.

The origins of the V-22 Osprey date back to the late 1970's with the Bell XV-15. The experimental aircraft showed that it was possible to use a tilt-rotor to transition from vertical to horizontal flight. Refinements to the aircraft improving control and reliability resulted in the V-22 Osprey. It first took to the air on March 19, 1989.

Due to numerous development issues, the V-22 Osprey did not enter service until 2007. Further refinements to the V-22 Osprey design incorporated a weight reduction program, plus improved and simplified manufacturing methods with an eventual goal of overall cost reduction. Rate of climb, service ceiling, engine efficiency, range, payload and speed were all eventually improved.

One 38 foot, three bladed rotor on each tilt wing propels the V-22 Osprey. The rotors, driven by separate engines, turn in opposite directions, eliminating the need for a tail rotor. When the rotors face upward, the V-22 Osprey can operate like a helicopter. The wings can be tilted forwards in just a few seconds so that the aircraft can fly like a conventional airplane. Part of engine power goes to a gearbox that operates the wing tilting function. Should a single engine of the V-22 Osprey fail, power from the good engine can be transmitted to the rotor of the failed engine through a connecting drive shaft. The remaining good engine can turn the rotors on both wings, enabling controlled flight.

Ten Marine V-22 Osprey aircraft were deployed to Al Asad Airbase, Iraq in late 2007. From there they flew over western Anbar province on reconnaissance missions as well as transporting troops and cargo. Through the summer of 2008 V-22 Osprey aircraft accumulated some 5,200 flight hours while engaged in some 3,000 sorties. During that time V-22 Osprey aircraft had come under small arms fire and had evaded a number of MANPAD (Man Portable Air Defense systems) attacks with no aircraft lost.

On Dec. 9, 2009 Marine V-22 Osprey aircraft along with helicopters transported some 1,000 U.S. Marines and 150 Afghan troops from Camp Bastion, northwest of Lashkar Gah in Helmand Province, to Now Zad Valley, Helmand Provence, in action against the Taliban.

Although we do not know how many V-22 Osprey aircraft were deployed to Afghanistan, the Marines stated that by mid February of 2011, V-22 Osprey aircraft had flown over 100,000 hours in country.

Twelve Marine V-22 Osprey aircraft participated in disaster relief in the Philippines after Typhoon Haiyan in 2013.

On Nov. 9, 2017 the U.S. Marine Corps disclosed that ready basic aircraft rates for the V-22 Osprey were at 48 percent. This was deemed unacceptable.

The U.S. Air Force deployed five V-22 Osprey Aircraft to Japan in April of 2018.

To date the V-22 Osprey has had nine crashes involving total aircraft losses with 39 fatalities.

On June 29, 2018 the U.S. Dept. of Defense contracted with Bell-Boeing for an additional 78 V-22 Osprey aircraft totaling some US$4.19 billion. The order is expected to be completed by 2024.

On Aug. 26, 2019 it was announced that U.S. Navy and U.S. Air Force V-22 Osprey aircraft will be receiving new avionics and related systems software under a US$29,919,648 order to Raytheon Co. Fulfillment of the order is expected by December of 2021.

Oct. 14, 2019:  Rolls-Royce, Indiana, USA, gets US$9,066,270 to procure three spare AE1107C engines in support of the V-22 Osprey program for the government of Japan. Work is expected to be completed in November of 2020.   The AE 1107C engine is said to have enhanced "hot and high" performance over the Allison T406 engine.

Nov. 6, 2019:  The Naval Air Systems Command awarded Bell-Boeing US$146,039,547  "to upgrade a total of nine V-22 Osprey aircraft from the Block B to the Block C configuration, as well as planned maintenance intervals for eight V-22 Osprey aircraft, in support of the Common Configuration-Readiness and Modernization (CC-RAM) program".  Completion is anticipated by March of 2022.

Nov. 11, 2019:  The United States Naval Air Systems Command awarded Bell-Boeing US$68,189,550 to provide "non-recurring and recurring engineering associated with the development, qualification test, integration, airworthiness substantiation, flight test demonstration and validation/verification of the government of Japan unique configuration into V-22 Osprey Block C aircraft and the V-22 Containerized Flight Training Device. This effort also includes logistics and training efforts, to include post-delivery reach-back support, aircraft preservation and de-preservation, storage, aircraft transit support as well as the remaining unique kits and installs in support of the government of Japan".  Work should be finished by Aug. of 2024.

Nov. 18, 2019:  The Naval Air Systems Command awarded Rolls Royce a US$1.2 billion contract for "sustainment support of the V-22 Osprey engine at various production, test and operating sites. Sustainment support includes program management, integrated logistics support, sustaining engineering, maintenance, repair, reliability improvements, configuration management and site support."

Nov. 20, 2019:  The Naval Air Systems Command awarded Hamilton Sundstrand Corp., U.S.A., US$10,075,122 to procure "non-recurring engineering and equipment for system integration lab activities in support of the V-22 Osprey aircraft Constant Frequency Generator Control Unit design improvement effort for the Navy, Air Force and the government of Japan".  Completion is expected in October of 2021.

Dec. 2, 2019:  The U.S. Defense Logistics Agency Aviation awarded Boeing-Bell US$$218,749,892 for "performance based logistics and engineering support for the V-22 Osprey platform".  Nov. 30, 2020 is the performance completion date.

Over 400 V-22 Osprey aircraft of all types have been produced to date.

RC V-22 Osprey

RC V-22 Osprey

The RC V-22 Osprey from Rotomast appears to have the complete functions of the actual aircraft.  Wingspan is 38.6 in. and length is 25.3 in.  Power comes from a pair of 2800 kV 2222 motors.  Weight is around 5 1/2 lbs.

The Blitz RC Works RC V-22 Osprey comes as RTF or ARF.  Its wingspan is 32 1/2 in., length is 33 1/2 in. and weight is around 41 oz.  Construction is EPO foam.  Three motors and used; two 3510 motors for the wings and one 2520 motor in the tail.  The aircraft is capable of transitioning from vertical to horizontal  flight and back by the use of a switch on the transmitter.  The angle of the rotors appears fixed in their final positions for either mode.  Vertical flight is accomplished with the motors positioned with their rotor blades upward.  Control of pitch, roll and yaw is limited in this flight mode while allowing some forward and reverse movement. When enacting horizontal flight mode, the motors go to their forward position, full aileron control banks the aircraft while rudder stick control turns the aircraft by use of motor differential thrust.  It appears that the ratio control stick will actuate the elevator control as usual.  Speed control does not appear to be limited.

The RC V-22 Osprey from Eflite is advertised as PNP.  It has a wingspan and length of 19 in., is made from EPO foam, has three motors, and weighs around 15 oz.  It appears to work in a similar manner to the Blitz RC V-22 Osprey, while its smaller size may be more suitable for indoor flying.
