Chapter 6
Details of the engine of Palenque
First, a basic scheme on my part:
Following is the pattern of how I see this engine:
- The liquid fuel flows from the tank through the conduct L1 directly in the piston pump.
- The liquid is put under pressure in the piston pump 120 bar should suffice.
- After the fuel flows through L2 under pressure in the evaporator compartment. These are located in the lid of the combustion chamber and the fuel evaporating through the heat of the thruster.
- At the same time the evaporation cools the cover of combustion chamber!
- During the evaporation in the chambers of evaporation a pressure of gas from 8 to 10 kg/cm 2. This is not enough to "go back", but enough however to push the evaporating fuel into the combustion chamber.
- In the combustion chamber itself should develop a media and constant pressure "upwards" from 4 to 6 kg/cm 2. This is not easy, then everything is under open!
- As the gas is pushed straight through the cylinders and can not disperse all, it should be possible to develop a strong enough pressure on the lid of the combustion chamber.
A small calculation:
The opening output engine should be round and a diameter of 40 cm. From this resulting 1250 cm 2. If then developed a constant pressure of 4 kg/cm 2 in the combustion chamber resulting a total pressure of about 5000 kg! (of course only if a degree of efficiency achieved of 100%, but that is not realistic).
Formula whole: 20cm x 20cm x Pi x 4kg/cm2 = 5,000 kg
But, already with 3000 kg of thrust the little spaceship should fly up well!
In the coming days will try to solve the chemical problem. Because I not are chemist and will have to go and ask.The end and conclusions » Chapter 7 »
