Problems solved by technology

[0003] The traditional alarm design is often carried out based on the airborne equipment, and the equipment failure is used as the alarm name. There are three shortcomings in the development of the new generation of aircraft: it is not easy for the flight personnel to intuitively understand the impact of the failure; it is necessary to wait for the aircraft to basically complete the system design before launching Alarm requirements design; it is difficult to give a systematic treatment procedure

Embodiment

[0030] The first step: According to the flight ground, the aircraft sliding takes off state, the aircraft aerial flight state, the person's life security process, the task operation status, the aircraft landing and the state of the stop state, the logic of the aircraft use phase functional requirements analysis.

[0031] Step 2: Analyze the functions required for airplane air flight status, establish the function trees in this state, such as figure 1 As shown, the first-level function "Providing Flight Control" function requires two sub-function "Rudder Safety" and "Computing Control", as the alarm requirements.

[0032] Step 3: The degree of affected sub-function as a warning name, such as figure 2 As shown, the "rudder surface manipulation" function is completely lost, the alarm name is defined as "rudder field failure", "rudder" function part (also maintaining simple flight), if the influence is serious and the corresponding alarm level is 2, then The alarm name is defined as...

Abstract

The invention relates to the technical field of aircraft design, warning, process design and the like, in particular to a warning and emergency disposal program design method. The design method comprises the following steps: establishing an aircraft function tree; and defining an alarm item according to each function in the function tree. Compared with the prior art, the technical scheme defines the alarm requirement according to each function in the function tree by establishing the aircraft function tree, is beneficial to carrying out the alarm design at the initial stage of aircraft design,and is beneficial to capturing the complete alarm requirement.

Description

Technical field [0001] The invention may relate to the technical field of aircraft design, alarm, process design, and particularly to a alarm and emergency procedure design method. Background technique [0002] During the design of the fighter design, the alarm is a very important design project whether the airborne system is still a seat. The flight personnel know the alarm information that is currently affected by the alarm system, according to the alarm information given, and combines personal knowledge and experience, and tries to avoid catastrophic accidents. Therefore, the alarm name is very important, and the comprehensiveness of the emergency deal is very important. The clear alarm name is convenient for flight staff to know what happened in time. Timely understand what the consequences have, and comprehensive emergency disposal procedures make full and accurate Disposal. [0003] The traditional alarm design is often based on airborne equipment, and the equipment fault i...
