a) To investigate, analyse and explain a typical Flying control System within the
rotary turbine structures and systems related to rotary aircraft flying control
systems and typical rotary flight controls of a military and or, a commercial
helicopter aircraft.
b) To understand the operation of the Rotor blades and their sub systems, defining
separate blade designs.
c) To understand the operation and function of a Rotor blade assembly and their
sub systems, components used in military helicopter aircraft.
Module learning outcomes assessed by this coursework:
On successful completion of this assignment, students will be expected, at threshold level, to be able to:
LO 4 – Classify and explain the role of components and system layouts related to Rotary Aircraft flying control
systems and illustrate this through drawings / schematics of typical rotary flight controls Landing Gear
systems.
LO 5 – Classify and explain the role of components and system layouts related to helicopter rotors and construct
simple drawings / schematics of typical helicopter rotor systems including any associated folding systems.
Task:
Write a 1000 word technical report which investigates, analyse’s and explain a typical Flying
control System within the rotary turbine structures systems related to rotary aircraft flying
control systems and typical rotary flight controls of a military and or, a commercial helicopter
aircraft.

Background:
The helicopter is a multi-use versatile aircraft that has been used in combat, search and
rescue, troop carrying, evacuation, and disaster relief purposes. Helicopters are designed and
built to be controllable. Aircraft are designed and built to be stable. Helicopters, unlike fixed
wing aircraft, obtain the required lift force to oppose weight from rotational movement of the
rotor blades.
Understanding how lift is produced by rotating blades is difficult for some, because the airflow,
which ultimately passes each rotor blade, consists of a number of seemingly conflicting
airflows, produced by rotation of the rotor blades, induced action, and airflow because of
forward or sideways flight.
Notwithstanding the difficulties, it is important that you understand the cause and the effects of
these airflows, and their interaction to the lift created. This is achieved by the Flying Control
Systems and Sub systems and associated systems to allow the Helicopter to move in all 3 axis
and paths of flight.
Equipment:
N/A
Procedure:
You are required to research, analyse, describe and discuss the areas identified below. You
are referred to the equipment and resources and to the reading/references section of this
assignment brief.
You are to write a 1000 word technical report (+/-10%) on this subject, making full use of
citations and references. You are to take into consideration the following key features:
- Research a military and commercial Helicopter of your choice, to produce
two labelled block diagrams of the operation of the Flying control Systems
and functions of its components within a helicopter.
One should be hand or computer drawn, the other can be an extract from
an Aircraft Maintenance Manual (AMM) or publication. (LO4)
To aid your research, you will find 30 separate diagrams on Moodle. - Describe the operation of Helicopter rotors and the basic function of its
associated components, used on Military Helicopters. This should include
:
One Main Rotor and One Tail Rotor design
Basic system components used to connect to the rotor
One Main and or Tail Rotor blade folding system. (LO5)
