Definitions
- the present invention relates to a device for automatically bringing the wheels of a
- This device is called L S A P (Landing Safety by Aircooled Process)
- the inertia of the wheels causes a rough touch of the tires on the bitumen during the landing
- compressed air cylinders are taken from the high compressor draw-off valve
- the compressed air is cooled beforehand by the radiators supplied by the cold wind from the
- blower nozzles distribute the compressed air over the cells by blower nozzles.
- the wheel will reach a speed of around 300 km / hour with a
- a non-return valve will be placed at the inlet of each compressed air cylinder.
- the cylinders will be placed empty at the departure of the plane in order to secure the cruise and
- An opening solenoid valve will be mounted on the other side of the compressed air cylinder
- the automatic contact control for starting wheel rotation is
- This device is operational to obtain a rotation of the front wheels
- the operation will be done automatically by a temperature probe set at 50 ° Celsius
- This heat detecting probe can be doubled by bogie as a safety measure
- the dashboard will therefore include compressed air pressure gauges,
- This device therefore allows both, at first, the rotation of the wheels
- - fig. 1 represents a bogie beam provided with the invention
- - fig. 2 represents a detail of the bogie with the device
- - fig. 3 represents a side view of the bogie and of the device
- - fig. 4 represents a detail of the wheel fitted with the device
- connection hoses (13) we also distinguish the connection hoses (13) from the air hoses
- FIG. 2 shows a detail of the bogie beam (1) with the brass pipes (7) fixed on
- Fig. 3 shows a side view of the bogie beam (1) with the pipes (7) and their
- the three arms of the delivery spider (11) are terminated by the blower nozzles (12)
- Fig. 4 shows the wheel (4) provided with the device with on the one hand, the three arms of
- the superheat temperature sensor (22) is fixed to the fixed brake block (14).
- Fig. 5 shows an enlargement of the high concave rim of the inner rim (9) of
- the alveoli (10) are
- the rim of the inner rim is 4 cm wide and 1 cm deep at its center.
- the three brass arms of the delivery spider (11) transport the compressed air to
- This sealing shell (8) is fixed on the end of the spider's arm
- Fig. 6 shows the plan of the energy source, namely, the compressed air coming from the
