The Ansat is a single-rotor helicopter with anti-torque rotor. Its fuselage is made of aluminium alloys and has four entrance doors.
Cargo loading/unloading can be performed through the main cabin doors or through the baggage compartment rear door. The transparent cabin windows and nose-cone are made of glass reinforced heat-hardened plastic. The fuselage nose-cone may house a radar. The fuselage has a smooth floor running through both pilots’ and main cabins. The height of the floor bay is 350 mm which permits installation of equipment. The inner area of the main cabin is 6.5 m3, which is one of the largest for a helicopter of its class (3.5 MT).
In future, this will enable development of various modifications such as: administrative, patrol, agricultural, medical, search and rescue, fire fighting, law enforcement, etc. Any of the above mentioned modifications may be equipped with an emergency flotation system. The first prototypes are powered by two Pratt & Whitney PW-206C turbine engines.
The baseline aircraft will be powered by PW-207 turbine engines with increased thermodynamic power for operation in hot environments. Air intakes may be equipped with sand-protection devices at the customer`s request. The rotorcraft flight structure consists of a four blade main rotor and a two blade anti-torque rotor. The main and anti-torque rotor hubs are hingeless with glass reinforced plastic torsion bars. The blades are multi-layered glass reinforced plastic. The Ansat houses a 16:4 reduction ratio double-reduction main gearbox in a magnesium casing equipped with internal and external oiling systems. Two hydraulic pumps, two oil cooling fans, two AC generators and a main rotor brake are mounted on the main gearbox. Mounted on the upper cover of the main gearbox are the swash plate, collective and cyclic pitch control systems and the steering gears. The supporting frame for the gearbox comprises six solid rods each of 13 mm diameter. The anti-torque gearbox is a cone type single-reduction gear unit with barbotage oiling system. The helicopter control system is electric remote control type, it is four-fold electronically reserved and two-fold hydraulically reserved. The basic helicopter is equipped with roll, pitch and yaw channel-situated angular velocity detectors. The Ansat undercarriage is skid-type with glass reinforced plastic cross carriage springs. Currently the No.1 prototype is undergoing ground testing to check the performance of all the aircraft systems. The factory certification tests followed by the certification check tests are scheduled to be completed by the year 2002.
