5、ceptor Systems for Aircraft Flight and Engine Controls RATIONALE Active Inceptor Systems are a class of pilot cockpit controllers that include a programmable servo actuator controlled feel-force system, and are being developed and flight tested for both fixed and rotary wing aircraft, some of which
6、are entering service. This Aerospace Recommended Practice fulfills the need for a document which defines the general characteristics and requirements for these feel-force control systems. FOREWORD Advances in flight control technology have helped optimize the performance of modern aircraft, and incl
7、ude selectable changes in aircraft configuration and extensive flight control system augmentation. Pilots require uniform and predictable aircraft response during changes in the configuration and flight conditions. This requirement is being addressed by active cockpit controllers, also known as Acti
8、ve Inceptors, which function as programmable, servo actuator controlled, feel-force systems. Active cockpit controllers may include a variety of pilot controls; side sticks, center sticks, engine controls, yaw controls, and cyclic and collective controllers. TABLE OF CONTENTS 1.

SCOPE 1.1 Purpose The purpose of this document is to develop the general characteristics and requirements for feel-force control systems for active cockpit controllers, also known as Active Inceptors. The document presents
16、technical material that describes the recommended key characteristics and design considerations for these types of systems. Where appropriate, the effects of platform specific requirements (e.g., single axis/dual axis, single seat/dual seat, civil/military, rotorcraft/fixed wing aircraft, etc.) are
17、clearly identified. The material developed will serve as a reference guide for: a. Aircraft prime contractors who want to understand active cockpit controller technology and develop their own set of requirements; b. Suppliers that develop active cockpit controller equipment and; c. Regulatory Author
18、ities who will be involved in the certification of these types of systems. 2.

ASTM G85 Standard Practice for Modified Salt Spray (Fog) Testing 2.2 Definitions 2.2.1 Cockpit Controllers INCEPTOR: A device that is used to provide pilot control inputs and covers a variety
33、 of aircraft pilot controls: side sticks, center sticks, pedals, engine controls and rotorcraft cyclic and collective controls. PASSIVE INCEPTOR: A passive control inceptor uses mechanical devices such as springs and dampers, sometimes in series with low bandwidth actuation, to generate the control
34、forces felt by the pilot. ACTIVE INCEPTOR: An active control inceptor uses high bandwidth actuation to generate the primary control forces felt by the pilot and thereby provide augmented control. This augmentation may include tactile pilot cues in real-time, such as variable spring gradients, force
35、breakouts, detents, ramps, gates and soft stops, to warn of mode engagements or impending operating or envelope exceedances. Actuation backup may be provided by parallel springs and dampers in the event of a loss of active capability. 2.2.2 Specific Inceptor Terms The following terms are used to def
36、ine inceptor performance throughout this publication. Figure 1 illustrates the application of most of the terms to a two-axis inceptor. 1. Reference Plane: The plane that contains both the pitch and roll axes of a two-axis inceptor. 2. Pivot Point: The point about which the inceptor rotates, also kn
37、own as a center of rotation. For the two-axis inceptor shown in Figure 1, the pivot points for both the pitch and roll axes coincide. 3. Grip Reference Point (GRP): The point on the controller/inceptor through which the pilot inputs all forces. These force inputs are input perpendicular to a line co
38、nnecting the GRP and pivot point in the plane of motion (pivot arm). The GRP on most grips is usually taken as the center of the middle finger position when on the grip. 4. Pivot Arm: The distance between the GRP and the pivot point in the plane of motion. 5. Pitch Axis: Axis about which the incepto
39、r rotates when the grip is deflected in the pitch direction. 6. Roll Axis: Axis about which the inceptor rotates when the grip is deflected in the roll direction. SAE ARP5764 Page 6 of 52 7. Heave Axis: Axis about which the inceptor rotates when the grip is deflected in the up/down (heave) direction
40、. This is often applicable to single axis rotorcraft collective controls (collective inceptor type). 8. Plane of Motion: The plane described by the rotation of the grip about the relevant axis (i.e., Pitch Plane of Motion). A Pitch Plane of Motion would be perpendicular to the pitch axis and the ref
41、erence plane.

True Null: This is the geometric null position of the inceptor and is described by a line perpendicular to the reference plane which connects the center of the grip mounting face and the pivot point. For the two-axi
44、s inceptor shown in Figure 1, this will correspond to zero displacement in the pitch and roll axes. For the single axis heave inceptor (Figure 2) the lowest inceptor position (at the bottom of the travel) may actually be greater than 0 degrees from horizontal, dependent on the aircraft type and spec
45、ific requirements. 10. GRP Null: This is described by a line drawn between the GRP and the pivot point when the relevant axis is at True Null. 11. True Position: Rotational displacement about the relevant axis from the true null in the plane of motion. 12. Reported Position: The displacement about t
46、he relevant axis reported by the position sensors. 13. Zero Force Null Band: The range of inceptor displacement, with no applied force, over which the inceptor is statically stable. The Zero Force Null Band is typically determined by gradually releasing the inceptor without assistance from the defle
47、cted position in both directions, and determining where it comes to rest. This is defined in terms of reported position. 14. Zero Force Null: The geometric center of the Zero Force Null Band. 15. Breakout Force: The force required at the zero force null position to initiate movement away from this p
48、osition. 16. Position sensor hysteresis: The difference in reported position (position sensor output) when at the same true position when approached from opposite directions. 17. Position sensor nonlinearity: The maximum deviation between the Reported Position and the True Position. SAE ARP5764 Page
49、 8 of 52 18. Position sensor gain/sensitivity: The slope of the best fit straight line through a series of sensor outputs corresponding to known sensor positions covering the sensor range. 19. Position sensor resolution: The smallest inceptor position change that the sensor can measure. 2.2.3 Control Systems for Active Inceptors The general functional requirements for the electronic controller, servo actuation system, the passive spring assem
