A Numbered Air Force (NAF) is a type of organization in the United States Air Force that is subordinate to a major command (MAJCOM) and has assigned to it operational units such as wings, squadrons, and groups. [1] A Component Numbered Air Force (C-NAF) has the additional role as an Air Force Component Command exercising command and control ...
A major command (MAJCOM) represents a major Air Force subdivision having a specific portion of the Air Force mission. Each MAJCOM is directly subordinate to Headquarters, Air Force. MAJCOMs are interrelated and complementary, providing offensive, defensive, and support elements. An operational command consists (in whole or in part) of strategic ...
Structure of the United States Air Force. The structure of the United States Air Force refers to the unit designators and organizational hierarchy of the United States Air Force, which starts at the most senior commands. The senior headquarters of the Department of the Air Force consists of distinct staffs in the Pentagon: the Secretariat or ...
Lanchester's laws are mathematical formulas for calculating the relative strengths of military forces. The Lanchester equations are differential equations describing the time dependence of two armies' strengths A and B as a function of time, with the function depending only on A and B. [1][2] In 1915 and 1916 during World War I, M. Osipov [3 ...
Froude number. In continuum mechanics, the Froude number (Fr, after William Froude, / ˈfruːd / [1]) is a dimensionless number defined as the ratio of the flow inertia to the external force field (the latter in many applications simply due to gravity). The Froude number is based on the speed–length ratio which he defined as: [2][3] where u ...
A: blue line = chord, green line = camber mean-line, B: leading-edge radius, C: xy coordinates for the profile geometry (chord = x axis; y axis line on that leading edge) The NACA airfoil series is a set of standardized airfoil shapes developed by this agency, which became widely used in the design of aircraft wings.
In aerodynamics, the torques or moments acting on an airfoil moving through a fluid can be accounted for by the net lift and net drag applied at some point on the airfoil, and a separate net pitching moment about that point whose magnitude varies with the choice of where the lift is chosen to be applied. The aerodynamic center is the point at ...
Flight (military unit) A flight is a small military unit within the larger structure of an air force, naval air service, or army air corps; and is usually subordinate to a larger squadron. A military aircraft flight is typically composed of four aircraft, though two to six aircraft may also form an aircraft flight; along with their aircrews and ...
