Description

Изобретение относится к области авиации, в частности к устройствам для защиты авиационных газотурбинных двигателей. The invention relates to the field of aviation, in particular to devices for protecting aircraft gas turbine engines.

Целью изобретения является защита основной сетки от обледенения и повреждения. The aim of the invention is to protect the main grid from icing and damage.

Изобретение поясняется чертежом, где изображена схема наземного защитного устройства воздухозаборника. The invention is illustrated in the drawing, which shows a diagram of a ground protective device of the air intake.

Наземное защитное устройство (НЗУ) содержит каркас 1, прикрепленную к нему основную сетку 2, охватывающую вход воздухозаборника 3, и снабжено перегородками, выполненными в виде полосок 4 из сетки и установленными перед основной сеткой 2. Ширина полосок 4 равна расстоянию между ними, а расстояние от основной сетки 2 до полосок 4 из сетки составляет половину ширины полосок 4. Ground protective device (NZU) contains a frame 1, attached to it the main grid 2, covering the inlet of the air intake 3, and is equipped with partitions made in the form of strips 4 of the grid and installed in front of the main grid 2. The width of the strips 4 is equal to the distance between them, and the distance from the main grid 2 to the strips 4 of the grid is half the width of the strips 4.

Устройство работает следующим образом. The device operates as follows.

Перед запуском двигателя самолета на аэродроме к его воздухозаборнику 3 прикрепляется НЗУ, которое задерживает поднимающиеся с земли предметы с помощью основной сетки 2 и полосок 4 сетки. Каркас 1 служит для предотвращения прогиба сетки 2. Перед полетом НЗУ снимается с воздухозаборника 3. Before starting the aircraft engine at the aerodrome, an NZU is attached to its air intake 3, which delays objects rising from the ground using the main grid 2 and strips 4 of the grid. The frame 1 serves to prevent the deflection of the grid 2. Before the flight, the NZU is removed from the air intake 3.

При работе в условиях обледенения лед 5 покрывает полоски 4 из сетки и те части основной сетки 2, которые расположены против зазоров между полосками 4 из сетки. Те части основной сетки 2, которые расположены против полосок 4, не покрываются льдом и сюда по криволинейным линиям тока 6 движется воздух. Полоски 4 служат также для защиты основной сетки 2 от повреждения. (56) Патент США N 2846023, кл. 55-306, 1958. When working under icing conditions, ice 5 covers the strips 4 of the net and those parts of the main net 2 that are located against the gaps between the strips 4 of the net. Those parts of the main grid 2, which are located against the strips 4, are not covered with ice and air moves here along curved streamlines 6. Strips 4 also serve to protect the main mesh 2 from damage. (56) U.S. Patent No. 2,846,023, cl. 55-306, 1958.
