|Therefore, we find that the air pressure under the wing is slightly higher than over him. As a result, the wing operates the lift. This component plays an important role in the low-speed aircraft, in particularly at the screw and an even greater role in non-motorized gliders. By the way, so the ratio of wing area to total area aircraft from the screw more than the jet, while the gliders - max. That is why doing on many planes modifiable geometry wing (so that jets could fly at low altitudes at lower speeds by increasing wing area). <br>|
Thus, effective control of the aircraft in combat and efficient maneuvering reduced in fact to the effective management and use of the "four forces", and how well they are used in the same plane and poorly in another, is dependent on dynamic characteristics of the aircraft itself, that is, from what it Designers have invested. <br>
Energetics of flight. <br>
To begin with, we say that the pilot, who was caught flying
low speed at low altitude - it's a bad driver. True, there are situation where it is simply necessary because some specific considerations. But in general, has too little capacity to fight the enemy. After a dogfight much determines the speed. And he cannot accelerate quickly (high air resistance at low altitudes) or dived, accelerated due to gravity. Note also that the thrust jet engine depends on the speed with which ejected the burned gases. And they are released at low altitudes worse, because is ambient air pressure.
