P80

Fiat-Avio solid rocket engine. In production. Vega's first stage, introduced advanced low-cost technologies that could be reused for future evolutions of Ariane-5 boosters. Solid propellant rocket stage. Vega's first stage, the P80 solid rocket motor, introduced advanced low-cost technologies that could be reused for future evolutions of Ariane-5 boosters.

Status: In production. Thrust: 3,040.00 kN (683,410 lbf). Gross mass: 95,000 kg (209,000 lb). Unfuelled mass: 7,000 kg (15,400 lb). Specific impulse: 280 s. Burn time: 107 s. Height: 7.50 m (24.60 ft). Diameter: 3.00 m (9.80 ft).

Vega's first stage, the P80 solid rocket motor, introduced advanced low-cost technologies that could be reused for future evolutions of Ariane-5 boosters. The new technologies mainly consist of: a 3 m diameter graphite epoxy filament wound case; low density rubber for the internal insulation; low binder content and high aluminum percentage for the propellant (HTPB 1912); simplified nozzle architecture using low-cost and lighter carbon phenolic material; consumable casing for the igniter; and an electromechanical thrust vector control using lithium ion batteries.

Chamber Pressure: 95.00 bar. Area Ratio: 16. Propellant Formulation: HTPB 1912.

Country: Italy. Launch Vehicles: Vega. Propellants: Solid. Stages: P80. Agency: Fiat-Avio.
