A Snapshot of the Kazan Ansat
Design work on the Ansat helicopter began at Kazan in 1993, with structural strength and aerodynamic calculations subcontracted to Kazan State Technical University, production of the rotor to Aviation Scientific Co. and transmission to Aeromechanica Co.
The first Ansat flight was on Aug. 17, 1999. On 14 September 2001, Ansat became the winner of a competition to supply 100 training helicopters to Russian armed forces by 2015. “Ansat” name in Tatar language can be translated as “easy or light”.
Design Features:
Optimized for aerodynamic efficiency and survivability in case of emergency landing (1m/s power-off touchdown speed) and with off-base routine maintenance. Ansat features traditional metal structure for simplicity and reliability. Meets FAR PT. 29 Category A and Russian AP-29 requirements
Equipped with shock absorbing seats for passengers. Conventional configuration high mounted tail boom carrying fixed horizontal stabilizer and two fins, two turbo-shaft power plants above the cabin
