it was made in catia. and as far as i know, there is no way of getting the stresses in it.Unit91Actual said:It looks like you made that in Abaqus (?). If so, did you run an FE simulation to see what types of stresses are in the engine? One of the biggest concerns in efficiency is thrust to weight ratio (T/W). If you want to take this to the next step, I recommend seeing what your stresses are like, and determining if you have too much / too little material. Factors of safety are also important.
efficiency is how much of the chemical energy of the fuel is actually converted into useful work. and calculating it is different because this design will have a totally different thermodynamic cyclegmax137 said:What exactly do you mean by 'efficiency'? Can you write down what you mean in words, and then take a stab and quantifying it? Why do you think calculating it is any different then the 'efficiency' calculations described in the automotive engineering textbooks?
