Airplane engine air inlet protecting structure and jet airplane

Abstract

The invention provides an airplane engine air inlet protecting structure and a jet airplane and relates to the technical field of aviation. A technical problem that birds in the air or floating objects in the air are easily absorbed into the airplane engine to damage the engine because an engine air inlet of the jet airplane is open in the prior art is solved. The airplane engine air inlet protecting structure comprises an air inlet protecting plate; the air inlet protecting plate is fixedly arranged on an airplane engine air inlet; the air inlet protecting plate is made of a rigid material; the air inlet protecting plate is of a conical shape and the external side surface of the air inlet protecting plate forms anti-bird collision surface; vent holes are formed in the air inlet protectingplate; the vent holes are placed in the air inlet protecting plate at intervals; the vent holes face towards the airplane engine air inlet and the edges of the vent holes can stop the birds from entering into the airplane engine air inlet via the vent holes. According to the airplane engine air inlet protecting structure and the jet airplane, the birds can be stopped from entering into the airplane engine air inlet via the vent holes so that the normal working of the airplane engine device can be guaranteed.

Description

technical field [0001] The invention relates to the field of aviation technology, in particular to an aircraft engine air intake protection structure and a jet aircraft. Background technique [0002] A jet aircraft is an aircraft that uses jet engines as a source of propulsion. The used jet engine of jet aircraft makes the aircraft fly forward by the recoil effect of the gas produced when the fuel burns and ejects at high speed backwards, which can make the aircraft obtain greater thrust and fly faster. [0003] At present, the aircraft engine inlet of known jet aircraft is directly exposed outside, that is, it is exposed, and birds in the sky have become the most harmful enemy to jet aircraft. Countless small birds such as sparrows and swallows have been hit or inhaled, and it is the large birds weighing more than 1 kg that threaten the safety of aircraft. Because the jet has 1 or several huge air intakes, a lot of air has to be sucked in to work. If flying birds or floa...
