Question

Following diagram represents ______

(a) gear retraction geometry in the nacelle

(b) gear retraction in fuselage

(c) gear retraction in wing fuselage junction

(d) gear retraction at wing tip

The question was asked in an online quiz.

Origin of the question is Gear-Retraction Geometry topic in section Landing Gear and Subsystems of Aircraft Design

Answer 1

The correct answer is (a) gear retraction geometry in the nacelle

To elaborate: Typical, gear retraction inside the nacelle is shown in the diagram. This type of arrangement can be seen in early prop aircraft. Gear retraction in fuselage or wing fuselage junction are nearly similar to each other.
