OBS

Speed-attitude correction is provided by the mach trim compensation system. Mach trim compensation automatically provides forces to the control column(elevator) to compensate for nosedown pitching moments of the airplane at high Mach number.

OBS

pitch trim compensator (DC-8); PTC (DC-8).

French

Domaine(s)
  • Commandes de vol (Constructions aéronautiques)
OBS

Un «pitch trim actuator» peut parfois être un vérin compensateur de Mach, mais il existe de nombreux avions auxquels la notion de Mach ne s'applique pas, mais qui sont quand même munis d'un «pitch trim actuator». Ce serait le cas, par exemple, du très populaire Dash8. Dans ce cas, on parlerait de «vérin de compensateur de profondeur», par exemple. Sur de nombreux avions, il n'y a pas de vérin distinct pour la compensation de Mach, mais simplement un circuit qui agit sur le compensateur de profondeur quand le centre de poussée recule à mesure que la vitesse de l'écoulement sur l'aile s'approche de la vitesse du son.

CONT

The elevator feel system supplies feel forces to the control system. The feel forces developed will vary depending upon airspeed and stabilizer trim. The feel system contains two basic units : the feel and centering mechanism [and] the feel computer. The feel and centering unit consists of a cam, spring-loaded follower, two hydraulic actuators and related linkage.

OBS

The "feel" is what allows the pilot to know how much pressure is needed for system operation.

OBS

The somatosensory system consists of numerous pressure receptors contained within the muscles, tendons, joints, and skin. This system reacts to the sensations resulting from pressures or stretch on joints, muscles and skin and also from slight changes in the position of internal organs. These are the forces that act on the seated pilot in flight. It is closely associated with the vestibular system and to a lesser degree, the visual system. They allow the pilot to sense certain complex motions and forces of flight such as aircraft feel(buffet, control forces, rudder, trim force) and "G" forces.

The aileron trim control system controls the movement of the aileron trim tabs to provide lateral trim. The system is controlled mechanically by a control knob on the control pedestal in the flight compartment.... The control knob is mounted on the end of a shaft in the trim control mechanism. A drum on the opposite end of the shaft is connected by a two-way cable system to a drum on a shaft located in the right wheel well. Another drum at the base of the same shaft is connected by a second cable system routed along the rear spar of each wing to the trim tab actuators. The actuators are connected to the trim tabs by a pushrod. A trim position indicator is connected mechanically to the trim control knob.

CONT

Speed-attitude correction is provided by the Mach trim compensation system. Mach trim compensation automatically provides forces to the control column(elevator) to compensate for nosedown pitching moments of the airplane at high Mach number. Control column position is effected by the Mach trim actuator installed at the lower part of the first officer's control column control mechanism. The actuator receives command signals from the stability augmentation computer. Mach number is computed from pitot and static air pressure input changes to the air data computer(ADC-1). The air data computer shapes the information and transmits it to the stability augmentation computer where it is further shaped and then transmitted to the actuator to command control column and elevator movement.

The electrical flying control system is based on two independent systems, the Elevator Aileron Computers(ELAC) and the Spoiler Elevator Computers(SEC). The Spoiler Elevator Computer System... consists of a trio of computers, which will produce commands in the roll axis by operating the two outer spoiler panels on each wing; speed-braking in flight by operating the three inner spoiler panels; lift-dumping after landing by raising all ten spoiler panels; stand-by pitch axis control in support of the ELAC by operating the elevators and automatic trim, also as a stand-by to the ELAC, by adjusting tailplane incidence.
