shock conen.

Brit.

/ˈʃɒk kəʊn/, U.S.

/ˈʃɑk ˌkoʊn/

Origin: Formed within English, by compounding. Etymons: shock n.³, cone n.¹

Etymology: < shock n.³ + cone n.¹

1. Physics. A conical wave front at which there is a sudden change of pressure, such as that generated by a supersonic aircraft or a missile passing through the air. Cf. shock wave n. 1.

2. Aeronautics. A cone shaped projection fixed in front of the air inlet of a jet engine of a supersonic aircraft, designed to slow the incoming air to a relative speed which is subsonic.
