ACCELERATED LIFE TEST ACCELERATED LIFE TEST A test in which certain factors, such as voltage, temperature, and so forth, are increased or decreased beyond normal operating values to obtain observable deterioration in a reasonable period of time and thereby afford some measure of the probable life under normal operating condi- tions, or some measure of the durability of the equipment when exposed to the factors being aggravated. ACCELERATING POTENTIAL The potential in electron beam welding that imparts velocity to the electrons, thus giving them energy. ACCELERATION BLOWOUT Inadvertent loss of combustion in a turbojet engine incident to an attempted acceleration and over- rich fuel mixture. Also called flameout. ACCELERATION FEEDBACK A sensing system for control of a missile by elimination of body bending effects and maintenance of angles of attack at predetermined values. Accelerometers are used to sense body accelerations, which are fed into the control systems
