← ScienceWhich consequence results when exceeding thermal design limits within pulsed detonation cycle?
A)Reduced compressor pressure ratios achieved
B)Accelerated heat exchanger fouling rates
C)Uncontrolled self-ignition thermodynamic runaway✓
D)Diminished deflagration-to-detonation transition efficiency
💡 Explanation
Uncontrolled self-ignition results from exceeding thermal limits because compression heating spikes temperatures past the fuel's auto-ignition point, triggering Thermodynamic runaway, rather than reduced performance, therefore causing catastrophic engine failure due to thermal limits imposed exceeding material's tensile strength.
