Problems solved by technology

[0005] However, mechanical solutions for operating piston motors in aircraft in the event of a fault have the disadvantage that they require additional maintenance effort and are also prone to failure
Furthermore, mechanical solutions offer only conditional possibilities for correcting or adapting the corresponding interference situation

Embodiment Construction

[0030] The invention is schematically illustrated with the aid of an embodiment in the drawing and will be described in detail later with reference to the drawing.

[0031] The method according to the invention is figure 1 The sequence shown in starts with method step 1 , in which a button is pressed to activate an emergency operation mode, followed by activation of an emergency operation control device in method step 2 and usually deactivating a standard control device. In method step 3 , the emergency operation control device deactivates a corresponding sensor provided for controlling at least one piston motor of the aircraft and in method step 4 uses the corresponding setting for controlling the actuation of the at least one piston motor The device is adjusted to a fixed and defined state. Furthermore, corresponding sensor values ​​of deactivated sensors are replaced by values ​​permanently stored in the emergency operation control device.

[0032] In method step 5 the at...

Abstract

A method is provided for operating a piston engine in an airplane in an emergency operating mode, in which a minimum power output of the piston engine is ensured in that an emergency operating mode is activated that is as much as possible independent of measured values of respective sensors provided for an operation of the piston engine, in which the measured values of the sensors are substituted with firmly specified values. A corresponding airplane is provided as well as to an emergency operation control unit for carrying out the provided method.

Description

technical field [0001] The invention relates to a method for operating at least one piston motor in an aircraft in an emergency operation mode, an aircraft having at least one piston motor, and an emergency operation control device for operating a piston motor in an aircraft. Background technique [0002] Aircraft components are subjected to enormous loads during operation. In particular, the piston motors for driving the aircraft and the sensors required for controlling the piston motors are loaded, for example, by strong temperature fluctuations and three-dimensional position changes during flight. [0003] Since the failure of the aircraft drive during flight or the failure of the controls for operating the aircraft drive poses a great potential hazard, the European Aviation Safety Agency requires that due to the control of the corresponding drive, such as a piston motor The risk arising from the loss of control through an error in the corresponding control must be suffi...
