The Indian Space Research Organisation has also enlisted Indian Air Force Chinooks during the development of its Reusable Launch Vehicle Technology Demonstration Program, with Chinook helicopters air-dropping two test vehicles during the RLV-LEX-01 and RLV-LEX-02 conducted on April 2, 2023, and March 22, 2024, respectively.
The Kaman HH-43 Huskie is a helicopter developed and produced by the American rotorcraft manufacturer Kaman Aircraft. [2] It is perhaps most distinctive for its use of twin intermeshing rotors, having been largely designed by the German aeronautical engineer Anton Flettner.
Tandem-rotor helicopters, however, use counter-rotating rotors, with each cancelling out the other's torque. Therefore, all of the power from the engines can be used for lift, whereas a single-rotor helicopter uses some of the engine power to counter the torque. [1] An alternative is to mount two rotors in a coaxial configuration.

Lockheed submitted the CL-840 design, a rigid-rotor compound helicopter with both a pushing propeller and a conventional tail rotor mounted at the end of the tail. [ 13 ] The Army announced Lockheed and Sikorsky as winners of Project Definition Phase contracts on 19 February 1965. [ 10 ]
Two aircraft were built to prove the tiltrotor design and explore the operational flight envelope for military and civil applications. [ 8 ] [ 9 ] In 1981, using experience gained from the XV-3 and XV-15, Bell and Boeing Helicopters began developing the V-22 Osprey , a twin-turboshaft military tiltrotor aircraft for the U.S. Air Force and the U ...
The Sikorsky CH-54 Tarhe is an American twin-engine heavy-lift helicopter designed by Sikorsky Aircraft for the United States Army.It is named after Tarhe, an 18th-century chief of the Wyandot Indian tribe whose nickname was "The Crane". [2]
In the mid-1960s, the helicopter was test flown by a number of government and military agencies, and also the military. The stability offered by the rigid rotor control system made the helicopter easy to fly, [ 2 ] and the lessons learned from the CL-475 rigid rotor were later used to develop the Lockheed XH-51 and AH-56 Cheyenne .
