CSDs are mainly used on airliner and military aircraft jet engines to drive the alternating current (AC) electrical generator. In order to produce the proper voltage at a constant AC frequency, usually three-phase 115 VAC at 400 Hz, an alternator needs to spin at a constant specific speed (typically 6,000 RPM for air-cooled generators).

The Jabiru 3300 is a lightweight four-stroke, horizontally opposed "flat-six" air-cooled aircraft engine produced by Jabiru Aircraft. The engines are direct drive and fitted with alternators, silencers, vacuum pump drives and dual ignition systems as standard. The engine is used to power homebuilt and ultralight aircraft. underside of a Jabiru 3300
An alternator is an electrical generator that converts mechanical energy to electrical energy in the form of alternating current. [2] For reasons of cost and simplicity, most alternators use a rotating magnetic field with a stationary armature . [ 3 ]
The development of modern rare-earth magnets makes the simple magneto alternator a more practical proposition as a power generator, as these permit a greatly increased field strength. As the magnets are compact and of light weight, they generally form the rotor, so the output windings can be placed on the stator, avoiding the need for brushgear.
In 1994, the first Canadian-produced DA20, a Rotax 912-powered A1 aircraft, was completed; it was the first Diamond aircraft available for sale in North America. Between 1994 and 1999, in excess of C$100 million was invested in the Canadian plant.

The Rolls-Royce Olympus (originally the Bristol B.E.10 Olympus) was the world's second two-spool axial-flow turbojet aircraft engine design, first run in May 1950 and preceded only by the Pratt & Whitney J57, first-run in January 1950. [1] [2] It is best known as the powerplant of the Avro Vulcan and later models in the Concorde SST.
