Project Description

COMPLETE DESCRIPTION

Helicopter lightweight, single-engine, quadruple, very used for tourist flights as it has reduced fuel consumption, good cruising speed and performance even with 4 people on board, but excellent machine also for training.
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 hinged and uses self-lubricated bearings, the blades are solid in the flip-up and free of taper, 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 4 v-belts, with a clutch that energizes them.
The 8860cc aspirated engine is electronically fueled with a filter, with a safety valve that in case of air intake air can suck air directly (unfiltered).
It has dual power supply system, with two generators, each one providing voltage to its group of candles, plus an alternator for battery charging 28 v.
Flying controls are through rod connections, assisted by hydraulic actuators.
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, gyro-compass, hsi, turn coordinator, fuel gauge, engine gauges and warning lights.
It can also be equipped with IFR instrumentation.
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) localization transmitter.
