Wave drag — is an aerodynamics term that refers to a sudden and very powerful form of drag that appears on aircraft and blade tips moving at high subsonic and supersonic speeds. Overview Wave drag is caused by the formation of shock waves around the aircraft … Wikipedia
Wave making resistance — is a form of drag that affects surface watercraft, such as boats and ships, and reflects the energy required to push the water out of the way of the hull. This energy goes into creating the wake.PhysicsFor small displacement hulls, such as… … Wikipedia

Drag divergence Mach number — The drag divergence Mach number (not to be confused with critical Mach number) is the Mach number at which the aerodynamic drag on an airfoil or airframe begins to increase rapidly as the Mach number continues to increase[1]. This increase can… … Wikipedia
High explosive anti-tank warhead — High explosive anti tank (HEAT) rounds are made of an explosive shaped charge that uses the Neumann effect (a development of the Munroe effect) to create a very high velocity jet of metal in a state of superplasticity that can punch through solid … Wikipedia
High-temperature superconductivity — Unsolved problems in physics What causes superconductivity at temperatures above 50 kelvin? High temperature superconductors (abbreviated high Tc or HTS) are materials that have a superconducting transition temperature (Tc) above 30 K… … Wikipedia

High-speed flight — In high speed flight the assumptions of incompressibility of the air used in low speed aerodynamics no longer apply. In subsonic aerodynamics, the theory of lift is based upon the forces generated on a body and a moving gas (air) in which it is… … Wikipedia
Parasitic drag — (also called parasite drag) is drag caused by moving a solid object through a fluid. Parasitic drag is made up of many components, the most prominent being form drag. Skin friction and interference drag are also major components of parasitic drag … Wikipedia
