They deliver more than 90 percent of the launcher’s total thrust at the start of flight and burn for 130 sec.before they are separated over a designated zone of the Atlantic Ocean.The payload fairing, mounted on the nose of the launch vehicle, protects satellites on the launch pad and during the initial trajectory through the Earth’s atmosphere.It is produced by RUAG Space, which is the world’s leading supplier of payload fairings made of composite materials.Ariane 5 utilizes two solid boosters, each standing more than 30 meters tall with 237.8 metric tons of propellant.The boosters are ignited on the launch pad once the main cryogenic stage’s Vulcain engine has stabilized its thrust output.To streamline the assembly process, Ariane 5’s vehicle equipment bay and ESC-A cryogenic upper stage are installed as a single unit atop its cryogenic core stage.

The thrust chamber is fed by two independent turbopumps using a single gas generator."It is with extraordinary sadness we can confirm the death of our friend and colleague, Anthony Bourdain," the network said in a statement."His love of great adventure, new friends, fine food, and drink and the remarkable stories of the world made him a unique storyteller.The booster stage’s solid rocket motor is made up of three segments: the 11.1-meter-long aft (lower) segment, which is loaded with 106.7 metric tons of propellant; the center segment, with a length of 10.17 meters and 107.4 metric tons of propellant; and the 3.5-meter-long forward (upper) segment, loaded with 23.4 metric tons of propellant.A propellant mix of 68 percent ammonium perchlorate (oxidizer), 18 percent aluminum (fuel), and 14 percent polybutadiene (binder) is used in the solid rocket motors.
