Propulsion • Inlets, Combustors & Nozzles • Subsonic & Supersonic Inlets
Pitot inlets are generally preferred over spike or ramp inlets for flight Mach numbers below:
(A) Mach 1.5
(B) Mach 3.5
(C) Mach 5.0
(D) Mach 0.3
Answer Key:
A
Step-by-Step Verified Solution
### Solution: Below Mach 1.5, the total pressure recovery across a single normal shock is very high (>93%), making the mechanical simplicity and low weight of a Pitot inlet superior to multi-ramp inlets. Correct: A.
