Description

Fireproof control panel for airplane

Technical Field

The utility model belongs to the technical field of fire protection systems, and relates to a fire protection control panel for an airplane.

Background

Whether the aircraft is in flight or on the ground, a fire is one of the most dangerous threats to the aircraft, and if not capable of extinguishing a fire in a timely manner, can cause serious damage to the aircraft and injury to aircraft, passengers, and ground personnel.

Aircraft are typically provided with a fixed fire suppression system for engine and APU fire suppression, including a fixed fire extinguisher, a fire suppression circuit, and a fire protection control panel. The fire control panel is the interface between the aircraft fire protection system and the pilot, providing fire indication and fire suppression operations.

The 25 th standard of airworthiness of transport aircraft in civil aviation regulation of China:

the CCAR 25.777, the position of each operating device of the cockpit must ensure convenient operation and prevent confusion and malfunction; when identical power plant operating devices are used for each engine, the operating devices must be positioned so as to prevent confusion with individually controlled engines.

25.1195 th fire suppression system, there must be a fire suppression system that serves each designated fire zone. The auxiliary power unit may use a separate "one shot" fire suppression system. For a given fire zone within the engine nacelle, two injections must be provided.

The CCAR 25.1523 article must consider the following factors to specify a minimum flight crew that is sufficient to ensure safe operation: workload of each crew member; the accessibility of the crew members to the necessary operating devices and ease of operation are concerned.

CCAR 25.1555, each emergency operating device must be red.

At present, the fireproof control panel of the civil aircraft mainly has the following forms and installation positions: 1. the fire-proof control panel adopts a fire-extinguishing handle with a fire alarm indicator light; is mounted on the cockpit control console. 2. The fire-proof control panel adopts the form of a fire alarm and fire-extinguishing button switch; is arranged on a control board at the top of the cockpit.

In recent decades, with the ever-changing layout of the cockpit and the ever-introduced new technologies and functions related to the flight, the flight safety has been further enhanced while the advancement and the ease of use have been improved.

However, in the current civil aircraft cockpit, as the control of the aircraft is more and more complex, the number of switches is more and more, and the requirement of the increasingly developed system control of the aircraft is not completely met.

In addition, for an airplane provided with a plurality of engines, the number of handles or switches on the fireproof control panel is multiplied, and if the traditional form and installation position are adopted, the contradiction between the control requirement and the installation space of the fireproof control panel cannot be fundamentally solved.

Therefore, how to make the control panel interface concise and clear, convenient and fast to operate, high in safety and integration level, and small in installation space requirement is a trend of development of future fireproof control panels.
