What are the advantages of four engined aircraft over twin engine aircraft?
Historically, the four engine design was used to ensure performance and reliability. Aircraft engines back in the early years of aviation were prone to failures and mechanical trouble, and with a four engine airplane, losing 1 engine meant the aircraft retained 3/4 of its performance, versus 1/2 with a two engine design. Additionally, engine technology at the time meant that some aircraft actually required 4 engines in order to have sufficient thrust for takeoff/climb (i.e, B-747). Today, the only real advantage a four engine aircraft enjoys is performance (as mentioned above), and an increased level of redundancy. Additionally, both of the advantages are rapidly dissolving, as no current commercial transports (other than A380 and 747) employ a four engine design.
Advantages of two stroke engine over a four stroke engine?
Explain the advantages of four-stroke engine over two-stroke engine
What is the world's largest commercial aircraft?
As of now, it's the Airbus A380, a massive wide-body, four-engine, double decker plane that seats over 500 passengers.
How did Charles Lindbergh fly over the Atlantic?
In a one-engine propeller aircraft, alone.
What is the primary advantage of rotary-winged aircraft over fixed-winged aircraft ?
Choppers can hover over a position; fixed wing cannot (other than Harrier type jets). Choppers can land anywhere and take off from anyplace; fixed wing aircraft NEED a large airstrip.
What is the main advantage of DC over AC for aircraft electrical power systems?
It doesn't have to be rectified. That's the ONLY advantage; the electrical systems in all but the smallest planes are 400Hz AC systems.
What are Straight wings and what advantage does it have over other wings?
Straight wings are basic wings that extend out of the fuselage of an aircraft with a 90 degree angle. The advantage of straight wing vs others, is that it is great on low speed aircraft due to low take off speed (because of the increase in lift).
Which engine is best for an aircraft?
It totally depends on what you are using the aircraft for. Sometimes you need power over fuel efficiency, sometimes you need fuel efficiency over power. It is dependent on the situation where the engine will be used. Some engine examples; Piston props (radial and v engine), internal combustion props, turboprops, turbofans, axial turbojets, centrifugal turbojets, ramjets and scramjets.
How do you beat the elite four in leaf green?
you need Pokemon that are strong and that an effective advantage over every elite four trainer. to beat the champion u need various Pokemon that have advantage types
Why you prefer four stroke engine over two stroke engine?
Four stroke engines are quieter than two strokes, but have less power.
How can an engine stall in an aircraft?
when you hear "stalling an aircraft", that means that they are reducing the amount of airflow over the wings, until the plane cant fly anymore. to overcome this, you push the nose forwards again.
What makes an aircraft jet engine start?
APU turns it over. These used to be on external cart on early jets but are now internal.
