Project

Project Ariane 6 EFF - Guyane

The Ariane 6 is the new European launch vehicle. In 2014, it was decided to move forward with the European launch vehicle program and bring Ariane 6 to life. The main goal of the vehicle is to provide reliable and low cost access to space for European countries without requiring public sector support. The differentiating element between Ariane 5 and 6 is the cost. Much effort has been made in vehicle studies to reduce costs so that it can be competitive against newer competitors such as Space X.

Ariane 6 will have two variants, one with two boosters and the second with four boosters (Ariane 62 and Ariane 64). When equipped with two boosters, it can develop a takeoff thrust of 800ton and with 4 boosters the thrust is 1500ton. The Ariane 6 P120C boosters are 13.5m long, 3.4m in diameter and receive 144ton of propellant mass. The thrusters are connected to the lower liquid propulsion module, which is composed of a single Vulcan 2.1 engine with a 137ton thrust, combustion liquid oxygen and liquid hydrogen. The top of the rocket has a Vinci engine with 18ton thrust and 30ton of liquid oxygen and hydrogen. At the end of its construction, the Ariane 6 will have a total height of 63 meters, 5.4 meters in diameter, a weight between 530ton and 860ton and can deliver loads between 5ton and 21ton.

The European Space Center in French Guiana, South America, which is already the Ariane 5 launch site, will also be the Ariane 6 launch site, but some changes will be needed. The new vehicle will have its launch pad and some new buildings that will support assembly and pre-takeoff inspections. There will be the new assembly facility, the new launch pad, the mobile gantry, the EFF and BSB reinforcement buildings. Slefty is working on structural analysis of the ESR Finishing Facility (EFF) and its integration with all mechanical equipment. This building will be the one where the floor finishing of each P120C booster is done.

This is a big project for Slefty and Europe that will boost the future of space in European countries.
