Development of multifunctional aircraft model Hiller Ten99 become conducted by American design engineers during the second half of 50-ies of the last century. Before the aircraft manufacturers was an important task to establish a multi-purpose aircraft that can be widely used both in civil and military aviation, in particular, the helicopter intended to be used to transport people and cargo transport, as well as a patrol agents and independent combat unit .
The helicopter was first developed under the requirements of the US Navy, however, since in the course of testing the aircraft was unable to meet all the requirements of the American military command, and for its commercial use because of the high cost he also did not fit, so the project and did not mass-produced.

In 1961, the helicopter model Hiller Ten99 has made its first test flight, and despite the fact that aircraft manufacturers had the intention to optimize the aircraft construction, the project was still very costly and could not fully justify the costs, in connection with which, in the early 1962 It was officially named closed.
The cabin Hiller Ten99 aircraft can accommodate up to 6 people, including one pilot and five troops, when it came to his military assignment. Among other things, the helicopter can also carry out transportation on its board of goods total weight of up to 726 kg, or else used as a combat aircraft, for which it was intended to equip a machine gun and two sets of unguided missiles to combat armored targets.
Experts note that the main competitor was the model Hiller Ten99 helicopter Bell HU-1, who turned Bole promising for use in military aviation, and therefore the military command and came to the opinion to abandon the use of the aircraft Hiller Ten99.
The power plant model helicopter Hiller Ten99, also called Hiller 1099, consists of a turboprop aircraft engine brand Pratt & Whitney Canada PT6, which is developing a thrust of 550 hp, it was also very costly in terms of its maintenance. Maximum aircraft Hiller Ten99 airspeed is 410 kilometers, while, as a matter aircraft can accelerate up to speed in 195 km \ h.
To date, there is only one aircraft model Hiller Ten99, which is part of the museum in the US dedicated to aeronautical engineering, manufactured by «Hiller Aircraft».
