VEGA E: M10 Motor


The Lyra program financed by the Italian Space Agency (ASI) enabled Avio to study the potential evolution of the Vega Launcher to increase useful load by 30%, up to 3000 Kg in a LEO 1 of 700 Km.

The goal of the program was to enhance the performance of the Vega Launcher by replacing the third stage and the AVUM stage with an innovative LOX/CH 4 liquid propellant system.

This new engine is designed to provide approx. 10 tonnes of thrust through the use of an expansion-type thermodynamic cycle. During the Lyra program, a full-scale MIRA-D demonstrator was built and tested.

The program also included the development of innovative guidance, navigation and control algorithms.

The experience and results obtained with the demonstrator engine LM10-MIRA constitute a reliable starting platform for development of the motor M10 for Vega E used in flight.
