What is the difference between lift and drag force?
Lift is the force that acts at a right angle to the direction of motion through the air. Lift is created by differences in air pressure. Drag is the force that acts opposite to the direction of motion. Drag is caused by friction and differences in air pressure.
Does a plane have to move faster or slower to generate more lift?
The amount of lift depends on the speed of the air around the wing and the density of the air. To produce more lift, the object must speed up and/or increase the angle of attack of the wing (by pushing the aircraft’s tail downwards). Speeding up means the wings force more air downwards so lift is increased.
Does air move faster over wing?
A wing is shaped and tilted so the air moving over it moves faster than the air moving under it. As air speeds up, its pressure goes down. So the faster-moving air above exerts less pressure on the wing than the slower-moving air below. The result is an upward push on the wing—lift!
What force is going against lift?
gravity
What is a stabilizer on an airplane?
At the rear of the fuselage of most aircraft one finds a horizontal stabilizer and an elevator. The stabilizer is a fixed wing section whose job is to provide stability for the aircraft, to keep it flying straight. The horizontal stabilizer prevents up-and-down, or pitching, motion of the aircraft nose.
Can a plane fly without a stabilizer?
Conventional airliners cannot fly without the vertical stabilizer. If it is lost during flight, the airplane would most likely crash.
Where is the engine located on a plane?
Modern airliners use winglets on the tips of the wings to reduce drag. The turbine engines, which are located beneath the wings, provide the thrust to overcome drag and push the airplane forward through the air.
What is the front of an airplane called?
A cockpit or flight deck is the area, usually near the front of an aircraft or spacecraft, from which a pilot controls the aircraft.
What is the right side of an airplane called?
The part that is on your right is starboard.
Can a airplane stop in the air?
Techincally, there is only one way for the aircraft to remain hanging motionless in the air: if weight and lift cancel each other out perfectly, and at the same time thrust and drag cancel each other out too. But this is incredibly rare. To stay in the air and sustain its flight, an aircraft needs to be moving forward.
How long does an airplane engine last?
Older and smaller jet engines typically have TBOs of 5,000 hours at the most. More modern engines have about 6,000 hours or more. With most business jets accumulating less than 500 hours of flying time a year, the schedule for modern jet engine MRO operations averages about 12 years or more.
How much does a plane engine cost?
Aircraft Pricing
| Aircraft model | Engine | New Price |
|---|---|---|
| Airbus A320 | GE, International Aero Engines | $98M |
| Airbus A321 | GE, International Aero Engines | $114.9M |
| Airbus A330-200 | ROLLS-ROYCE, GE, Pratt & Whitney | $231.5M |
| Airbus A330-200F | Pratt & Whitney, ROLLS-ROYCE | $234.7M |
What type of oil do jet engines use?
Mobil Jet oils are suitable for a wide range of turbine applications in both commercial and military service. They are also suitable for aircraft-type gas turbine engines used in industrial or marine applications.
Why was the 747 discontinued?
Boeing is ending the 747 production line in 2022 while Airbus just delivered its last A380 fuselage to the assembly line in France in June. High operating costs and efficient twin-engine alternatives marred orders for both planes in the 2010s as the manufacturers promised jets that could fly further for cheaper.
Why are 777 engines so big?
The reason why: the new engines offer far greater fuel efficiency and much less noise thanks to composite 3D printed materials and larger fan blades. By reducing weight with previously unattainable materials, the engines are able to draw more air, which greatly improves the efficiency and noise part.
