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…show more content…
Density altitude could be higher than the actual altitude and higher density altitude could have a great effect the lifting or hovering ability of the helicopter in which that could ultimately limit the engine’s power and stop speed on most helicopters. When the collective pitch control lever is raised, the blade angle of all the rotor blades increases uniformly and that creates the lift that the helicopter to take off vertically [4] WHY DOES IT TO BE CONTROLLED The helicopter flight control needs to be manipulated by the pilot in order to achieve and maintain a controlled aerodynamic flight so that we ensure that the altitude increases gradually and that it does not overshoot. 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…show more content…
Collective lever – The collective pitch control changes the pitch angle of all the rotor blades collectively [2]. If a collective input is made, all the blades change equally in which that result in a helicopter increase or decrease in its total lift. 2. Cyclic stick – is a central pillar that either pilot can manipulate, this type of input changes the pitch angle of the rotor blades cyclically. The change in cyclic pitch has effect on changing the angle of attach and this causes the blades to fly up or down in sequence.[3] 3. Anti-toque pedals – these pedals control the direction that the nose of the craft points[3] Figure 2: location of flight controls in a helicopter The helicopter flight
