Question

Which of the following is correct?

(a) Wake of a canard can stall the engine

(b) Wake will increase engine efficiency

(c) Wake will increase engine thrust

(d) Wake will increase engine performance

I have been asked this question in my homework.

My doubt stems from Configuration Layout topic in division Configuration Layout Considerations of Aircraft Design

Answer 1

The correct choice is (a) Wake of a canard can stall the engine

For explanation I would say: While designing an aircraft, designer should not forget about aerodynamic interaction of different components. If a canard is required then the interaction of canard with other components should be considered during layout. If canard wake enters into the engine it can stall the blades and as a result, engine performance will be reduced as well.
