Aerospatiale is a regrouping of several French aeronautical companies like Sud-Aviation, Nord-Aviation and SEREB.

-In Chatillon-sur-Bagneux they developed ramjet and Turbo-ramjet projects and later they produced reverses, variable intakes, nozzles, noise suppressors, etc. Here we emphasize the work on the Concorde.

-They have made many agreements with other companies for manufacturing all kinds of aeronautical equipment.

-Currently it belongs to the European group EADS (European Aviation and Defense Systems).

-Aerospatiale with Eurpropulsion are the main contractors of the SRM P-80 Boosters engines. These engines are a launch aid for the Ariane 5, and are attached to each side of the main rocket. They will drop off when the solid fuel has been used entirely.

-In the picture we can see the complexity of the design and the materials involved in the final outlet nozzle of the attached auxiliary engines. In Europropulsion we find Snecma (currently named Safran), MTU, ITP and RR.

-The French aeronautical complex is vast and involves many companies at the same time. For example, for the famous Exocet missile or for studies on "Scramjets" Aerospatiale can cooperate with companies like Dassault Aviation, SEP, Snecma or ONERA. They even are collaborating with the German Daimler-Benz Aerospace.

-The ANS missile was built jointly with MBB. The four air-intakes indicate that it is a scramjet.

-When using hybrid propulsion systems such as ANS for the propulsion of anti-ship missiles the engine is made of a high-energy rocket with a scramjet around it. This system we will see below in the ANNG (Anti-Navire-Nouvelle-Generation) by Aerospatiale-DB.

-A prototype of this type of scram-jets, perhaps used for trials, we see in the MAE, in their engine stores.

-Above we had a rear view and below the front side is shown, with four sockets and the central cone removed.

-From appendix 6: With regard to missile production, Aerospatiale had the “División des Engins Tactiques” which became Euromisil/EADS, just like the helicopter division became Eurocopter.

-Their greatest success, because of the media coverage during the Falklands War, was the Exocet missile. (French for Flying-Fish).

-There were variations depending on use. There are surface-, air- and submarine-lauched versions.

-The MM-38 and MM-40 were used similarly.

-The Exocets were "Fire and Forget" and its best feature was that shortly after its launch it stabilized on its way to the goal. It went above the waves at a height between 1 and 3 meters depending on the state of the sea.

-The AM-39 could be dropped in the air from airplane or helicopter.

-Now we pass on to the Exocet engines. There have been several. The MM-38 has a SNPE booster, models Epervier and  Eole V with concentric nozzles. SNPE stands for Société nationale des poudres et des explosifs (French National Society of Gunpowder and Explosives).

-The MM-40 used the Gerfaut and Aither. The AM-39 the Helios and the SM-39 the Narval. They are all SNPE engines.

-Approaching so low it was almost undetectable. If the distance was high, due to the slight curvature of the earth, it was even more difficult.

-From appendix 9. This company that currently belongs to the EADS group manufactures aeronautical materials (Caravelle, etc), for all kind of military missiles. And in cooperation with SEP (before LRBA, SEPR, see main text) they have built rocket engines like those of the famous Exocet missiles, etc.
