Description
Elements of system of automatic control of pressure in a cabin of plane (ACPRS) for planes of type TU-334.
The system of automatic control of pressure ACPRS is intended for maintenance in гермокабине the plane of comfortable conditions for passengers and crew of the plane at change of conditions of flight on height.
With a view of maintenance of reliability of work ACPRS, the equipment is executed in a reserved variant: the duplicated calculator and the built - in drive of management (two automatic channels and one manual emergency channel of management).
EACH AUTOMATIC CHANNEL PROVIDES PERFORMANCE OF THE FOLLOWING FUNCTIONS:
- Change of absolute pressure with the set speed on optimum trajectories at ascent and at decrease;
- Stabilization of absolute pressure at constant height of flight;
Elements systems of automatic control are executed by pressure ACPRS with application of precision gauges of measurement of pressure, a digital computer and a small-sized drive of management. ACPRS possesses the built - in control and corresponds to requirements of norms of safety АP-25 and FAR - 25. ACPRS successfully competes to similar systems of domestic and foreign manufacture.
