British sounding rocket. Petrel was a larger sounding rocket built by Bristol Aerojet using the same tube-launch technique as Skua. A total of 240 Petrels were launched from 1967-1982 from many sites around the world.

Status: Retired 1982. First Launch: 1967-06-01. Last Launch: 1982-08-11. Number: 231 . Gross mass: 200 kg (440 lb). Height: 3.30 m (10.80 ft). Diameter: 0.19 m (0.62 ft). Apogee: 140 km (80 mi).

2 stage vehicle consisting of 1 x Chick x3 + 1 x Petrel.

Subtopics

Petrel 1 British sounding rocket. Petrel was a larger sounding rocket built by Bristol Aerojet using the same launch technique as Skua. Three Chick rockets blasted the upper stage and payload out of a 10-m long launch tube. The 4.5 kN Lapwing second stage burned for 30 seconds. A unique aspect was that the Chick boosters could be recovered and reloaded with propellant.

Petrel 2 British sounding rocket. Improved Petrel using four Chick boosters and a lengthened Lapwing second stage which provide 4.5 kN thrust for 40 seconds. Petrel 2's were also fired as targets for missile tests at Woomera.
