Why does lift occur?
Lift occurs when a moving flow of gas is turned by a solid object. The flow is turned in one direction, and the lift is generated in the opposite direction, according to Newton’s Third Law of action and reaction. Because air is a gas and the molecules are free to move about, any solid surface can deflect a flow.
Why is the Concorde nose bent?
During takeoff and landing, Concorde flew at a steep angle, with its front end tilted skyward and its tail pointing down. If a conventional plane were in this position, its nose would block the pilots’ view. As the plane took off, landed, and taxied, the pilots tilted its nose forward so that they could see the runway.
Why does the nose of an airplane pitch up?
To maintain the necessary lift to hold the aircraft up in the air, the nose is slightly pitched upwards. Pitching the nose upwards, increases the aircraft’s angle of attack (AoA). Since, lift is directly proportional to the AoA of the aircraft, the airplane flies at slight nose pitch up attitude, even in level flight.
Why are aircraft wings curved at the end?
A significant source of drag (air resistance) is actually caused by the high pressure under the wing, which causes air to flow up and over the wingtip before spinning off in a vortex.
Why do cruise ships have a slight nose up attitude?
In other words, that slightly nose high attitude in cruise is engineered in. As has been said elsewhere, basically, because passengers like it and it’s comfortable. You get to sit leaning slightly back which is much more comfortable than sitting bolt upright or, even worse, leaning forward.
How many nose cones did the SR-71 Blackbird have?
The SR-71 had a detachable nose (photo #2), and could change between three different nose cones depending on the mission. I haven’t found a lot of information on the three, other than what this site and this site mentions:
