The tankards were bottom heavy, apparently to make them stable on moving surfaces.

The ash contaminated oil systems and clogged air filters, and scratched moving surfaces.

This is achieved by passing the fibers between differentially moving surfaces covered with card clothing.

The butterfly tail consists of two all moving surfaces, with wood sandwich leading edges and fabric covering elsewhere.

Moving surfaces cause amplitude, Doppler frequency, and pulse modulation of the return.

Five computers translate a pilot's actions into electronic commands that move surfaces, changing the plane's speed and direction.

Modern models use mechanical or electronical timers to move control surfaces at preset times.

Linear relationships which describe moving surfaces across some form or forms of dimension.

Their most common purpose is to carry moving surfaces, principally ailerons.

For measuring velocity and length on moving surfaces, laser surface velocimeters are used.
