Swedish police with a Bell 429 A Eurocopter AS365 N3 Dauphin 2 of the Victoria Police Air Wing.. Police aviation is the use of aircraft in police operations. Police services commonly use aircraft for traffic control, ground support, search and rescue, high-speed car pursuits, observation, air patrol and control of large-scale public events and/or public order incidents.
These studies culminated in the testing of the first prototype engine, designated YT63-A-3, in April 1959. [1] In 1960, the US Army settled for a rotary wing platform. The YT63-A-3 first flew in a variant of the Bell 47 helicopter in 1961. A modified version of the engine (YT63-A-5) with the exhaust pointing upwards (to avoid grass fires) soon ...
The A-7 was the first rotary-wing aircraft designed for combat, [22] armed with one 7.62×54mmR PV-1 machine gun, a pair of Degtyaryov machine guns, and six RS-82 rockets or four FAB-100 bombs. World War II
A rotary-wing aircraft, rotorwing aircraft or rotorcraft is a heavier-than-air aircraft with rotary wings that spin around a vertical mast to generate lift. The assembly of several rotor blades mounted on a single mast is referred to as a rotor .
The machine features rotating VTOL engines and a cockpit that swivels along with the upper and lower guns fixed to it. The craft was flown by Tom Cruise's character Jack Harper in the sci-fi film Oblivion.

In 2013, Bell introduced the 412EPI, which includes an electronic (digital) engine control for a PT6T-9 engine upgrade and a glass cockpit display system similar to the Bell model 429. Also featured is a Garmin touchscreen navigation system, and the BLR Strake and Fast Fin upgrades for improved hover performance. [ 4 ]
The proposed mode of operation was to land and take off as a tail-sitter, using the wing as a conventional rotor. The craft would then tilt over to horizontal flight and lift would be provided by cyclic pitch variation of the rotor wings, with the wing tip ramjets now angled to provide forward thrust. [5]
