Question 3: Advantages and disadvantages of hydraulic system of aircraftHydraulic systems are used for operation of different components of small and large aircrafts, including: flight control surfaces, brakes, constant-speed propellers, landing gear, thrustreversers, spoilers and wing flaps. Some of the advantages and disadvantages of these systems are discussed below.AdvantagesUses incompressible fluid: hydraulic systems use incompressible fluids that results to greater, more efficient and consistent power output or force. This also results to minimal energy loss as all energy is transferred to the required area of the aircraft.Force multiplication: hydraulic systems use a small amount of hydraulic fluid to multiply small forces into large or unlimited forces and transmit them efficiently to remote areas of the aircraft where they are required. The pilot only requires to apply a small force that is then multiplied into a large force to perform the required function.Simple design and easy to install: hydraulic systems have a simple design comprising of few components that are very easy to install and maintain. Efficiency: precise aircraft control is very important especially during critical flight conditions. Hydraulic systems are able to respond efficiently and very quickly to control inputs[ CITATION Mac17 \l 1033 ]. Pilots rely on these systems to perform different flight control functions without any worry on whether they will respond or the time they will take.
Reliability and dependability: hydraulic systems operate on very simple mechanical principles. They have very few moving parts that significantly reduce failure risks. This increases the efficiency, reliability and dependability of hydraulic systems.Less space and easy to maintain: hydraulic systems comprise of few moving components.This reduces space requirements of these systems and also makes their maintenance to be easy. Less components also makes hydraulic systems to be cost-effective to install and maintain.Lightweight: hydraulic systems are also lighter than most of the other mechanical systems of an aircraft. Shock hazard free: hydraulic systems do not require electricity in order to function. As a result of this, hydraulic systems are not vulnerable to shock hazards and there likelihood of fire hazards are very low[ CITATION Sim12 \l 1033 ]. This makes them safer than most of other mechanical systems.DisadvantagesThe fluid used in hydraulic systems is highly pressurized thus it poses risks such as burns and bruises if the fluid leaks and gets in contact with human body.Hydraulic systems are susceptible to leaks thus require frequent checks and maintenance.Hydraulic pipes can burst resulting to series injuries to humansIf a leakage occurs in hydraulic systems particularly in hot conditions, the hydraulic fluid can catch fire.
