What kind of engines does the airplane have?!
Turbo jet engines (oil, but high speed thrust), turbofan engines (integrated turboprop, low speed fuel and high speed turbojet thrust), use the culvert to solve the cusp supersonic problem.
The piston engine (generally used for small aircraft, such as aircraft movement, can be used in low speed, high shock resistance to real-time propeller tip) turboprop engine (fuel, but can only be used for low speed (and piston like) are generally used for short-range airliner)
