storage battery

Aviation; Aeronautics

A battery composed of several secondary electrical cells. A discharged storage battery can be recharged by placing it across a source of direct current until the chemical composition of the plates ...

secondary cell

Aviation; Aeronautics

A battery which can be recharged after it has been discharged. The action in which chemical energy is changed into electrical energy is reversible. This means that electrical energy from a battery ...

radar beam

Aviation; Aeronautics

A beam of focused electromagnetic energy radiated by radar. It is similar to a flashlight or searchlight beam, except that the frequency of the electromagnetic energy is beyond the visible range.

cantilever beam

Aviation; Aeronautics

A beam with all of its support inside the beam itself. It uses no external struts, braces, or wires. A diving board is an example of a cantilever beam.
