Project Description

COMPLETE DESCRIPTION

Helicopter lightweight, two-seater, two-way helicopter, used by the flying schools as it provides the student with a great sense of command, also used for aerial photography such as photography or territory monitoring, as it has reduced fuel consumption and a decent cruising speed in two.
Aluminum foil and steel tubular structure, equipped with elastic padding shoes.
The anti-clockwise rotor consists of 2 blades with symmetrical profile, steel with a honeycomb reinforcement inside. It is mounted on the shaft with a rocker hinge and uses self-lubricated bearings, the blades are solid in the flap and free in taper, they have blocks to limit the flip down. The step change hinge is oil bath.
The tail rotor, always on the rocker, uses an elastomer joint.
Transmission from the motor to the gearbox takes place with 2 v-belts, with a clutch that energizes them.
The 5800cc aspirated engine is a carburettor equipped with a filter, with a safety valve that in case of air intake air can suck air directly (unfiltered).
It has a dual power supply system, with two generators, each one providing voltage to its group of candles, plus an alternator for 12 volt battery charging.
Flight checks are direct, not servile, through auction links. A spring (trim) can be actuated to lighten the cyclic.
Equipped with a “governor” system (active over 80%) keeps the engine speeds adjusted to the required effort.
The tanks are placed at the top, so the feed is down, without the help of pumps, but with a tap on the line, for safety.
The electrical system provides a “master” switch that disconnects the battery from the system, but the tachometer remains powered in any case with a motor in motion.
The instrument panel contains: altimeter, airspeed indicator, vertical speed indicator, rotor and engine tachometer, artificial horizon, manifold pressure gauge, direct reading compass, fuel gauge, engine gauges and warning lights.
Equipped with a 118 – 136Mhz airborne radio communication radio, equipped with interphone, plus one VOR for navigation, a C mode transponder and an ELT (121.5Mhz) frequency transmitter
