Embodiment Construction

[0039] The following description provides many different embodiments, or examples, for implementing various features of the invention. The elements and arrangements described in the following specific examples are only used to express the present invention in a concise manner, and are only used as examples rather than limiting the present invention.

[0040] An engine intake guard with deicing capability, such as figure 1 As shown, it includes a supporting framework 1 and a protective net 2; the protective net 2 is fixed on the supporting framework 1, preferably, the edge of the protective net 2 is screwed to the supporting framework 1 to realize the fixing of the protective net.

[0041] The protective net 2 includes a protective base 21, and a through hole 22 is provided on the protective base 21, such as figure 2 shown.

[0042] It is worth noting that the shape of the through hole 22 in this embodiment is circular, but those skilled in the art can understand that the pr...

Abstract

The invention is applicable to the technical field of aircraft anti-icing, and provides an engine intake protection device with deicing capability, including a support frame and a protective net; the protective net includes a protective base, and the protective base is provided with through holes; An installation groove is opened on the support frame, and an exciter is fixedly installed between the protective base and the installation slot, and there is a gap between the exciter and the protective base of the protective net; the exciter includes a pulse coil. The protective device of the present invention can simultaneously solve the problem of foreign matter being sucked into the engine and the protective net freezing to reduce the air intake of the engine; the deicing efficiency of the present invention is high, and it can also avoid the accident that the removed crushed ice is sucked into the engine and causes damage to the engine blades; The exciter of the present invention is controlled separately, and the exciter is started or works with high power for the icing area or the area with serious icing, and the exciter in the other areas does not work or works with low power, thereby reducing energy consumption.

Description

technical field [0001] The invention relates to the technical field of aircraft anti-icing, in particular to an engine intake protection device with deicing capability. Background technique [0002] Helicopters take off and land in a variety of environments, so that the air entering the engine contains dust, sand and weeds and other debris, and there is a danger of birds hitting the engine during flight. Therefore, it is necessary to install protective devices at the engine intake to prevent Prevent debris and birds from being sucked into the engine. When the aircraft is flying in the air, if it encounters icing weather conditions, icing will occur on the engine protection device, which will seriously affect the engine intake air field and threaten flight safety. [0003] Patent CN110107405A discloses an engine air intake protection grid, which consists of heating components arranged horizontally and vertically to form a protection grid. The protection grid can prevent larg...
