Emeraude VE121

Emeraude was a step toward larger liquid propellant launch vehicles, building on the Veronique and Vesta experience. It burned 12.8 metric tons nitric acid/turpentine pressure-fed propellants in 91 seconds. The engine was gimbaled for pitch and yaw control, with aerodynamic fins controlling roll. In anticipation of the next step, Saphir, a dummy Topaze stage topped the vehicle to confirm aerodynamic characteristics. The first three launches were failures due to propellant sloshing. This was remedied in the later tests.

Payload: 395 kg (870 lb) to a 200 km altitude.
