For example, helicopters can ascend and descend without acceleration or deceleration, while ascent is typically coupled with acceleration for aircraft. Note that in the table, X indicates that any relationship between the two forces can possibly exist, which is aircraft type dependent. Depending upon the relative magnitude of these forces, there are several flight conditions that may exist, as listed in the table below. Lift causes the plane to gain altitude, while the vehicle’s weight-due to gravity-works to reduce altitude. Inferrable from their directions, thrust causes the plane to move forward, while drag is the resistance-principally air-to forward motion. In the figure above the four basic force vectors acting on an aircraft are shown. The Essentials of Aerodynamics and Flight Mechanicsįorces acting on an aircraft. This is primarily due to our improved understanding of essential flight mechanics, such as the impact of the boundary layer in aerodynamics activity. In this brief history of time, aircraft design and flight capabilities have increased phenomenally. It has only been a bit longer than a hundred years since we developed vehicles that could sustain flight, although this has been a goal for many millennia longer.
