Question 1
In a scenario where a jet engine operates at a flow condition with a Mach number of 2.5, calculate the stagnation properties, assuming air behaves as an ideal gas with a specific heat ratio of 1.4 at a temperature of 300 K.
💡 Hint: Start with the stagnation temperature formula first and remember to adjust both variables.
Question 2
Discuss the implications of a normal shock occurring in the supersonic flow of a high-speed aircraft at cruise altitude. Include effects on efficiency and performance.
💡 Hint: Consider both thermodynamic effects and practical implications on aircraft design.
