Embodiment Construction
[0032] The following is a detailed description of the specific implementation of the patent of the present invention, giving the design idea and the calculation method of important structural dimensions. Those skilled in the field of aero-engine main combustion chamber design can reproduce the related products of this patent according to this method.
[0033] 1 design input
[0034] The gas generator design requires the following parameters to be known:
[0035] 1) Air flow: W a
[0036] 2) Air pressure: P a
[0037] 3) Inlet temperature: T in ≈288K
[0038] 4) Outlet temperature: T out ≈1100K
[0039] 2 Aerothermal Calculation
[0040] 1) Fuel flow W f
[0041] W f = W a L 0 α ...1
[0042] Among them: L 0 =9 is the theoretical air volume
[0043] α=3 is the total residual gas c...
