Assuming you are referring to the electrical power system:
Weight
Light weight inductor cores on alternators, solenoids, Transformers etc. The compromise is 400c/s AC 3phase.
Low weight conductors, minimal volts drop over distance, compromise 115volts
Stability
115v 400c/s within mechanical feasibility of reliable constant speed drives for alternators. 12pole/6000rpm.
Versatility
For DC systems 24v is the minimum for acceptable volts drop over wiring distances encountered. Batteries can be small and light. Some compatibility and backup capability with the 26v 400c/s instrument systems.
Safety
Voltages within safety capability of insulation exposed to a wide environmental range of temperature, humidity, vibration, and aircraft fluids. All safety systems able to detect and trip 'out of range' voltage, current, frequency, and earth faults.
Terminations, plugs and sockets have to be selected for the aircraft environment and to consider security and corrosion.
It is a system that has evolved from years of learning from experience.
What else can I help you with?
What happens if reactive power enters the system?
Reactive power entering the system will increase the system voltage.
What is the eligible eye power to study Aeronautical Engineering?
There is no eye power necessary to study Aeronautical Engineering, or Aerospace. Engineering is the design of the aircraft, so it is independent of eye power.
What is the life expectancy of a nuclear power plant?
Design Basis Life Expectancy of a Nuclear Power Plant is 40 years.
Instead of aircraft battery is 24 volt dc why aircraft use 28 volt dc?
An aircraft battery is usually 28 volts DC because the need for power is greater in an aircraft than in a diesel truck. Having the 4 extra volts is a type of insurance policy so that the battery does not go dead while the plane is in the air.
Why is 400 Hz used as an aircraft power supply?
Although most all utility power in the world use either 50 Hz or 60 Hz, 400 Hz power systems are typically used in large aircraft. The reason for the higher frequency is that most of the power system parts, especially the 400 Hz alternator and 400 Hz motors are much smaller compared with similar 60 Hz equipment of the same power rating. In aircraft, every pound saved in equipment weight, equates to about a five pound savings in gross weight during flight. When equipment weight is reduced, both airframe structure and fuel load can also be reduced. As flux is inversely proportional to speed and speed is proportional to frequency Higher the frequency lesser the flux required.Lesser the flux,lesser the core size.Lesser the size means less weight.Hence the pay load can be increased. Also frequency above 400 hz not taken because the radiation takes place beyond this.

What is a power driven aircraft?
An aircraft with an engine.
What is power plant maintenance selection system mass aptitude testing?
he Power Plant Maintenance Positions Selection System (MASS) is a battery of skill and ability tests designed and validated to aid in the selection of candidates for power plant maintenance positions. This test battery measures the mental abilities found to be important for successful job performance. Reference: http://www.dom.com/jobs/tests.jsp
UAV Propulsion System Market?
A UAV (Unmanned Aerial Vehicle) propulsion system refers to the combination of components that power and control the movement of an unmanned aircraft. The propulsion system typically includes an engine or motor, a propeller or rotor, and a control system that regulates the speed and direction of the aircraft.
What power systems are comparable in design to aircraft power systems?
there are many power systems But one power system could Be POWER:High voltage Battery But very powerful AND THE DESIGN OR MANUFACTURER OF THE SYSTEM IS NOT RELEASED TO THE PUBLIC IN THE US FOR CERTAIN SECURITY ISSUES
What are some highly complex technological systems?
An aircraft carrier would be an example of a technologicaly complex system. As would be a railway system, or a national electric power grid.
What is a catapult launch lift and how does it work?
Do you mean the launcher used on aircraft carriers? This is operated by steam power, the aircraft is hooked to it, the pilot runs up engines to full power, does final checks on aircraft systems, then signals GO and the catapult is fired. Aircraft can reach 150 mph in 2 seconds, gaining enough lift to clear the deck.
What is thrust in an aircraft?
Thrust is the power made by a jet engine to propel an aircraft.
How much minimum engine can work for an aircraft?
It depends on the size of the aircraft and the power of the engine
What type of information should be stored in a non volatile memory during a power failure in a system designed to control the navigation in an aircraft?
eltrouo or true
