Summary the different engines that can be found

Summary

This case analysis evaluates the placement of the different
engines that can be found in the aircraft design. As the placement of the
engines has a very big impact on the aircraft performance. Therefore, this case
analysis will evaluate how the placement of the engines will influences the
aircraft in many ways. For instance, safety, structural weight, drag, control,
maximum lift, propulsive ef?ciency, maintainability, and aircraft growth
potential.

Significance
of the Problem

Everyone’s
surely has their own view and reason on the different placement of the engines
in the aircraft design. For instance, wing-mounted engines, aft fuselage engine
placement, and three engine designs.

 

Alternative
Action 1

Wing-mounted
engines normally can seem using on larger aircraft.

 

Advantages

Such
engines placement will help to minimum the parasite drags and probably minimum
the weight. Engines are quite heavy therefore placing them in the correct
position will help to keep the balance of the aircraft, so that the aircraft
won’t tend to pitch down or up during flight. In a situation where the engine
failure, the inboard location will help to minimize the yaw moment of the
aircraft due to the asymmetric thrust.

Disadvantages

This
kind of engine placement poses as a threat to the basic wing structure because
in an event if a blade or turbine disk failure, it will result in very
difficult to maximize the inlet efficiency and making accessibility for the
engineers on the ground to perform the maintenance much more difficult. In an
event of making improvement to the existing engine design. For example,
increase engine to larger diameter in the later date, designers and engineers
will have to redesigned and rebuild the whole entire wing. The point of placing
the engine at the correct position will help to keep the balance of the
aircraft, therefore it is a challenge that the designers face during the design
phase of the aircraft to determine the position of the engine if not it will
affect the balance of the aircraft.
