The invention relates to the field of helicopter alarming system design, in particular to a helicopter VNE alarming method. The helicopter VNE alarming method comprises the following steps that whether a helicopter is at a powered state or not is judged; the density height at the powered state is judged; a never exceed speed at the powered state is obtained through calculation; the never exceed speed at the powered state is obtained through calculation; the density height at an unpowered state is judged; a never exceed speed at the unpowered state is obtained through calculation; the never exceed speed at the unpowered state is obtained through calculation; and the never exceed speed obtained through calculation is judged, and accordingly a first alarming signal or a second alarming signalis sent out. According to the helicopter VNE alarming method, VNE is divided into powered VNE and unpowered VNE according to whether an engine works normally in the flying process of the helicopter or not, meanwhile changes of VNE along with influences of the atmosphere and the flying weight are automatically calculated, dynamic VNE tone alarming is achieved, and a pilot is facilitated to conductsafety judgment in the high-speed flying process at different flying states.
Description
technical field [0001] The invention relates to the field of helicopter warning system design, in particular to a helicopter VNE warning method. Background technique [0002] Commonly used helicopter warning systems are more focused on warning whether each system component or equipment is faulty, and the not-to-be-exceeded speed (VNE) limit is usually placed in the flight manual, and VNE changes with changes in the atmospheric environment and flight weight , it is not convenient for pilots to judge VNE during flight. Contents of the invention [0003] The object of the invention is to design a helicopter VNE warning method, so that the pilot can judge VNE during flight. [0004] Technical scheme of the present invention is: [0005] A helicopter VNE warning method, comprising the steps of: [0006] Step 1, determine whether the helicopter in flight state is in a powered state, if so, proceed to step 2; otherwise, proceed to step 5; [0007] Step 2. Judging whether the ...
