インストールする前に、エージェントに与えられる指示の中身を確認できます。
Turbojet: intake, compressor, combustor, turbine, nozzle. Turbofan: bypass flow around core, better fuel efficiency, lower noise. Bypass ratio: ratio of bypass to core flow, high BPR for subsonic transport. Turboprop: turbine drives propeller via gearbox, efficient at low speed. Compressor pressure ratio: determines thermal efficiency and specific thrust.
Ideal cycle: isentropic compression, constant pressure heat addition, isentropic expansion. Thermal efficiency: eta = 1 minus 1 over r_p to power k-1 over k. Specific fuel consumption: fuel flow per unit thrust, measure of efficiency. Component efficiencies: polytropic efficiency for compressor and turbine. Turbine inlet temperature: key design parameter, limited by material capability.
Rocket equation: delta-V = Isp times g0 times ln m0 over mf. Specific impulse: Isp = thrust over mass flow times g0, measure of propellant efficiency. Liquid propellants: RP-1/LOX, LH2/LOX, hypergolic NTO/MMH. Solid propellants: HTPB-based, simple, reliable, not throttleable. Hybrid: solid fuel with liquid or gaseous oxidizer.
Convergent-divergent nozzle: accelerates flow from subsonic to supersonic. Area ratio: determines exit Mach number and expansion ratio. Nozzle efficiency: accounts for friction and non-uniform flow losses. Thrust coefficient: CF = thrust over P_c times At, measures nozzle performance.
| Pitfall | Fix |
|---|---|
| Ignoring off-design performance | Engine must perform across full flight envelope |
| Overexpanded nozzle at sea level | Check nozzle exit pressure vs ambient |
| Underestimating turbine cooling | TIT limits require significant cooling air fraction |
| Wrong Isp units | Clarify whether Isp is in seconds or N s/kg |
