The Éridan is a two-stage French sounding rocket, which results from the use of the Stromboli engine (also used on the Dragon and Dauphin) for the first and second stages.[3] [4]
It belonged to a family of solid-propellant rockets that also encompasses the Belier, the Centaure, the Dragon, and the Dauphin.[5] [6] As the most powerful version of this series it could lift payloads from 100 to 420 kg to heights of 200 to a maximum of 460 km. Its ascent time is between 230 and 350 seconds.[7]
Total thrust was 90.00 kN (20,232 lbf) with a gross mass of 2,127 kg (4,689 lb). The rocket had a height of 9.92 m (32.54 ft), a diameter of 0.56 m (1.82 ft) and a span of 1.55 m (5.10 ft).
The main launch site was Kourou, but the first flight on 26 September 1968 from this site failed. Twelve additional launches took the rocket to altitudes of 196 – 420 km between 12 April 1969 and 14 November 1979. Two Éridan were launched in January and February 1975 off the Kerguelen Islands.
