MIL-STD-704 Aircraft Electrical Power Characteristics is a United States Military Standard that defines a standardized power interface between a military aircraft and its equipment and carriage stores, covering such topics as voltage, frequency, phase, power factor, ripple, maximum current, electrical noise and abnormal conditions (overvoltage and undervoltage), for both AC and DC systems.
The corners between the sections of the curve define the limits of the power factor (PF) that the generator can sustain at its nameplate capacity (the illustration has the PF ticks placed at 0.85 lagging and 0.95 leading angles). In practice, the prime mover (a power source that drives the generator) is designed for less active power than the ...
The power factor in a single-phase circuit (or balanced three-phase circuit) can be measured with the wattmeter-ammeter-voltmeter method, where the power in watts is divided by the product of measured voltage and current. The power factor of a balanced polyphase circuit is the same as that of any phase. The power factor of an unbalanced ...
Angle notation can easily describe leading and lagging current: . [1] In this equation, the value of theta is the important factor for leading and lagging current. As mentioned in the introduction above, leading or lagging current represents a time shift between the current and voltage sine curves, which is represented by the angle by which the curve is ahead or behind of where it would be ...
Modern warfare is warfare that diverges notably from previous military concepts, methods, and technology, emphasizing how combatants must modernize to preserve their battle worthiness. [1] As such, it is an evolving subject, seen differently in different times and places. In its narrowest sense, it is merely a synonym for contemporary warfare.
Combat effectiveness is the capacity or performance of a military force to succeed in undertaking an operation, mission or objective. [1] Determining optimal combat effectiveness is crucial in the armed forces, whether they are deployed on land, air or sea.
Armoured warfare or armored warfare (American English; see spelling differences), is the use of armoured fighting vehicles in modern warfare. It is a major component of modern methods of war . [ 1 ] The premise of armored warfare rests on the ability of troops to penetrate conventional defensive lines through use of manoeuvre by armoured units.
In modern warfare, to take into account that to some extent both linear and the square apply often, an exponent of 1.5 is used. [11] [12] [3]: 7-5–7-8 Lanchester's laws have also been used to model guerrilla warfare. [13] The laws have also been applied to repeat battles with a range of inter-battle reinforcement strategies.
