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.
The helicopter was unable to be recovered and was destroyed in place. [63] [64] To compensate for the loss, the ADF added two ex-U.S. Army CH-47Ds to the fleet which are expected to be in service until the introduction of the CH-47Fs in 2016.

In December 2006, Columbia Helicopters purchased the type certificate of the Model 107 from Boeing, with the aim of eventually producing new-build aircraft themselves. [48] In 2023, Columbia Helicopters began a program of purchasing older Model 107-II and CH-46E airframes, and refurbishing them into Model 107-IIs for sale.
The Cheyenne achieved speeds over 200 knots (230 mph; 370 km/h), but as a compound helicopter was unable to qualify for speed records in helicopter categories. [23] View of AH-56 nose and canopy. The Cheyenne had a two-seat tandem cockpit featuring an advanced navigation and fire control suite.

The Ka-50 and its two-seat version Ka-52 are high-performance combat helicopters with day and night capability, high survivability and fire power, to defeat air targets and heavily armoured tanks armed with air defence weapons. It was designed to be small, fast and agile to improve survivability and lethality. [16]
