I'm conduction a scale model experiment of thrust production in combustion chamber by using different types of fuel source.
Comparing the thrust produced by using hydrogen gas, kerosene and petrol.
Hydrogen gas = 142 MJ/kg
Kerosene = 42.8 MJ/kg
Petrol = 46.4 MJ/kg
What are the instrument to be use for measuring thrust output of the combustion chamber through combustion of the fuels?
What values do we measure? (eg. airspeed at output of combustion chamber/ temperature/ thrust)
