The invention relates to an aircraft back embedded type composite material integrated double-S-shaped air inlet way, belongs to the field of aircraft structure design, and relates to an improvement of an air inlet way structure. The air inlet way is a tubular S-shaped structural member consisting of an air inlet way cover 2, annular reinforcing ribs 3, a reinforcing ring 1 in cup joint with a lip port, a reinforcing ring 4 in butt joint with the back section of the air inlet way and sandwich foams 5. The air inlet way structure is integrally molded by a composite material tow laying technology, and is added with the annular reinforcing ribs for improving the strength and rigidity requirements of the air let way structure; and gaps L among the reinforcing ribs are 170-200 mm. The air inlet way is suitable for an air inlet way with small pipe diameter and difficult assembly, has the advantages of simple structure, light weight, easy assembly, high size precision, good pneumatic appearance, large improvement of structure strength and rigidity of the air inlet way, capability of bearing higher load and long service life, and can be widely applied to the technical field of structural design of medium and small-sized military unmanned aerial vehicles.
