Zefiro 23
Part of Zefiro Family
Fiat-Avio solid rocket engine. In production. Carbon epoxy filament wound case; low density EPDM insulation; HTPB 1912 composite propellant. Used on Vega launch vehicle. Solid propellant rocket stage. The Zefiro 23 was derived from a 16-metric ton solid rocket motor development (Zefiro 16) initiated by Fiat-Avio, now Avio S.p.A., with company funding and contracted by the Italian space agency ASI.

The Zefiro 23 was derived from a 16-metric ton solid rocket motor development (Zefiro 16) initiated by Fiat-Avio, now Avio S.p.A., with company funding and contracted by the Italian space agency ASI. The Zefiro-16 motor had already completed three successful firing tests by the end of 2006. The Zefiro-23 motor features included: a 1.9 m diameter carbon epoxy filament wound case; a low density EPDM insulation; HTPB 1912 composite propellant; a nozzle based on a flexible joint technology; a consumable igniter; and an electromechanical thrust vector control system.

Chamber Pressure: 106.00 bar. Area Ratio: 25. Propellant Formulation: HTPB 1912.



Country: Italy. Launch Vehicles: Vega. Propellants: Solid. Stages: Zefiro 23. Agency: Fiat-Avio.
