Helicopter Control Seminar Report

1. Introduction and Background on Helicopter Control

Helicopters are classified by their rotary wing aircraft which is the main rotor. Helicopters a capable of directing the altitude system, which is their vertical takeoff or lending. The first helicopter was but a guy called Igor Sikorsky in 1909[7]. The Helicopter’s power comes from a piston engine or a gas turbine which moves the rotor shaft and causing the rotor to turn and then the helicopter rotor achieves the lift by pushing the air beneath it downwards as it spins [ 7].

HOW THE ALTITUDE SYSTEM WORKS

Firstly an altitude is the distance measurement in a vertical up direction between the reference and the object. In aviation altitude is measured using either Mean sea level (MSL) or logical

The helicopter needs to be controlled also to avoid or reduce steady state errors that take place after the transient response has decayed. To ensure that the helicopter moves in a deliberate way we need to control it. The altitude is controlled to ensure a desired taking off or lending rate.

THE INPUTS AND THE OUTPUT

The input of the helicopter control system is the voltage to angle the system, which in essence include the three flight inputs, the collective lever, the cyclic stick and the anti-torque pedals because voltage is then applied to the pedals (the controls of the

The output of the system is the position (m) above the ground/ the altitude which is shown in Figure 2 above. Photo taken by Namhla Mabombo

THE REQUIREMENTS THAT THE PASSANGERS HAVE ON ITS PERFOMANCE

One requirement of the most requirement that the passenger have on the performance of the helicopter is that for it to rise gradually and for the altitude to not change drastically meaning for the helicopter to not bounce in the air making them uncomfortable.

User requirements of the helicopter include safety, which perhaps can be accomplished by having an Amsafe airbag seatbelts and according to Robison R44 Raven which is safer helicopter the helicopter should be less squirrelly in gusty winds and also near obstacles.

THE ENVIRONMENTAL CONCERNS

The environmental concerns on the helicopter control include the gravitational force that is always acting on any particle that has weight hence the pilot must determine the proper loading weight because improper loading can cause the loss of control or less than an optimal maneuverability of the aircraft. The wind and the air density also influences the helicopter’s takeoff and landing. Temperature is also of concern because too much heat will cause the metals inside the engine to wrap or even
