Frank and Pilbeam try to help Brenda run an awning factory while the owner is away on vacation; but stumble on the principles of flight when an awning, tied to a mammoth's back, catches the wind. The Inventor teaches them how to turn this to their advantage. Topics covered: air pressure, flight, aeroplanes, wind. 14: Somewhere Over the Mammoth
Supersonic flight is flight faster than the speed of sound. Supersonic flight is associated with the formation of shock waves that form a sonic boom that can be heard from the ground, [10] and is frequently startling. The creation of this shockwave requires a significant amount of energy; because of this, supersonic flight is generally less ...
The basic principles of air navigation are identical to general navigation, which includes the process of planning, recording, and controlling the movement of a craft from one place to another. [ 1 ] Successful air navigation involves piloting an aircraft from place to place without getting lost, not breaking the laws applying to aircraft, or ...
[2] He was the first true scientific aerial investigator to publish his work, which included for the first time the underlying principles and forces of flight. [ 16 ] In 1809 he began the publication of a landmark three-part treatise titled "On Aerial Navigation" (1809–1810). [ 17 ]
The "targets" for guidance systems are one or more state vectors (position and velocity) and can be inertial or relative. During powered flight, guidance is continually calculating steering directions for flight control. For example, the Space Shuttle targets an altitude, velocity vector, and gamma to drive main engine cut off.
Forces of flight on a powered aircraft in unaccelerated level flight. Understanding the motion of air around an object (often called a flow field) enables the calculation of forces and moments acting on the object. In many aerodynamics problems, the forces of interest are the fundamental forces of flight: lift, drag, thrust, and weight. Of ...

The principles of flight dynamics are used to model a vehicle's powered flight during launch from the Earth; a spacecraft's orbital flight; maneuvers to change orbit; translunar and interplanetary flight; launch from and landing on a celestial body, with or without an atmosphere; entry through the atmosphere of the Earth or other celestial body ...
