Ariane 1

The Ariane 1 is the first model in the series of Ariane rockets. It emerged from the Europa 3 of the failed European project. The development costs for the Ariane 1 amounted to DM 1.7 billion (approx. € 860 million).

Technology

With a takeoff weight of up to 210 t Ariane 1 had a height of 47.4 m and a diameter of 3.8 m. According to the plan, they should have a payload capacity of max. 1.7 t reach in the GTO. However, it turned out that the specific impulse of the third stage HM -7 engine was higher than calculated, whereby the actual payload capacity max. 1.85 t in the GTO was. It was the Ariane 1 transport a large or two smaller satellites.

The Ariane 1 has three stages:

• The first stage was equipped with four Viking engines Société européenne de propulsion.
• The second stage with a Viking engine. The Viking engines of the Ariane 1 consumed the hypergolic propellant combination nitrogen tetroxide / UDMH
• The third stage had a run with the combination of hydrogen / oxygen HM -7 engine with a thrust of seven tons.

The following two models Ariane 3 and Ariane 2 were only slightly modified versions of the Ariane 1 and also the Ariane 4 built largely built on the Ariane 1. Only the Ariane 5 presented represents a genuinely new development

The overall low number of starts and the few starts from 1985 due to the advent of much more powerful Ariane 3 in 1984 and the somewhat stronger Ariane 2 in 1986.

Start list

This is a complete list of all start .. All made ​​from the launch site ELA -1 of the European spaceport in Kourou, French Guiana. For the Ariane 1, the launch pad of Europe was rebuilt 2 rocket. It was also used for the launch of the Ariane 2 3.

¹ NOT necessarily the target orbit of the payload - but the path on which the payload was suspended from the third stage.

² The payloads are listed as they were one above the other or side by side housed (in rare cases ) in the payload fairing. The top payload first, then the second highest and so on.
