Kestrel \Kes"trel\ (k[e^]s"tr[e^]l), n. [See Castrel.] (Zo["o]l.) A small, slender European hawk ( Falco alaudarius), allied to the sparrow hawk. Its color is reddish fawn, streaked and spotted with white and black. Also called windhover and stannel. The name is also applied to other allied species.

Note: This word is often used in contempt, as of a mean kind of hawk. ``Kites and kestrels have a resemblance with hawks.''

Douglas Harper's Etymology Dictionary

kind of falcon, c.1600, earlier castrell (15c.), probably from Middle French cresserelle, which apparently is related to crecerelle "rattle," from Latin crepitacillium "small rattle," diminutive of crepitaculum "noisy bell, rattle," from crepitare "to crackle, rattle;" possibly from the old belief that their noise frightened away other hawks.


n. 1 Any of various small falcons of the genus ''Falco'' that hover while hunting. 2 The common kestrel, ''Falco tinnunculus''

  1. n. small North American falcon [syn: sparrow hawk, American kestrel, Falco sparverius]

  2. small Old World falcon that hovers in the air against a wind [syn: Falco tinnunculus]

Kestrel (rocket engine)

The Kestrel engine is an LOX/ RP-1 pressure-fed rocket engine. The Kestrel engine was developed in the 2000s by SpaceX for upper stage use on the Falcon 1 rocket.

Kestrel was built around the same pintle architecture as the Space X Merlin engine but does not have a turbo-pump and is fed only by tank pressure.

Kestrel is ablatively cooled in the chamber and throat and radiatively cooled in the nozzle, which is fabricated from a high strength niobium alloy. As a metal, niobium is highly resistant to cracking compared to carbon-carbon. According to SpaceX, an impact from orbital debris or during stage separation might dent the metal but have no meaningful effect on engine performance. Helium pressurant efficiency is substantially increased via a titanium heat exchanger on the ablative/niobium boundary.

Thrust vector control is provided by electro-mechanical actuators on the engine dome for pitch and yaw. Roll control (and attitude control during coast phases) is provided by helium cold gas thrusters.

A TEA- TEB pyrophoric ignition system is used to provide multiple restart capability on the upper stage. In a multi-manifested mission, this design would allow for drop off at different altitudes and inclinations.

Kestrel (disambiguation)

A kestrel is a type of bird.

  • Common kestrel, the most common species

Kestrel may also refer to:


The name kestrel (from French crécerelle, derivative from crécelle, i.e. ratchet) is given to several different members of the falcon genus, Falco. Kestrels are most easily distinguished by their typical hunting behaviour which is to hover at a height of around over open country and swoop down on prey, usually small mammals, lizards or large insects. Other falcons are more adapted to active hunting in flight. In addition, kestrels are notable for usually having a lot of brown in their plumage.

Kestrel (dinghy)

The Kestrel was the first sailing dinghy especially designed to have a fibreglass hull.

After a slow start, due to resistance to the new material, the Kestrel grew in popularity. This success led to more and more classes changing their rules to allow fibreglass construction. Today, the class is still a popular choice, particularly for 'club' racers and training schools. The design has been updated by Phil Morrison and has most recently been built by Hartley Laminates.

Kestrel (surveillance system)

Kestrel is a wide-area persistent surveillance system used on aerostats at U.S. forward operating bases in Afghanistan to monitor the surrounding areas.

The system is equipped with electro-optical and infrared cameras, providing day/night force protection and overwatch to troops.
