To calculate the specific impulse for the Rolls-Royce Gnome engine, we need specific information about the engine’s thrust, burn time, and mass of propellant.
It is defined as the thrust generated per unit of propellant expended and is expressed in seconds.
where,
- is the specific impulse of the rocket engine (in seconds, s)
- F is the Thrust Produced
- ṁ is the mass flow rate of propellant in KG/Sec
- g0 is the acceleration due to gravity
