Model 400-X Feedback Control Loader System
Model 400-X Feedback Control Loader System was designed to meet the world’s highest levels of certification from the JAA, FAA, and military equivalents for rotary and fixed-wing aircraft, but can be adapted for a variety of training simulation apparatus such as steering wheels, throttles, collectives, seat shakers, and tillers. Utilizing minimal to zero-backlash gearboxes in a variety of configurations in conjunction with DC brush type motors, friction and inertia are virtually zero and are not present in the flight controls.
Our unique coupled-mass servo force-loop technology provides the technical foundation for all our systems. Combined with highly responsive electric actuators and sophisticated math software models, the 400-X Feedback Control Loader System provides the highest fidelity control loading anywhere.
The aircraft control model is based on a real aircraft data model. Any type of control system can be simulated: fully boosted, partially boosted or non-boosted. The spring rate and the damping can be varied so that the system can simulate the change in the force gradient and damping that is present with the change in dynamic pressure.
Friction, stops, breakouts, boost actuators, non-linear gearing, non-linear hinge moments and auto-pilots (simulated and real) are available with this system.
For aircraft that have separate left and right controls, separate actuators can be utilized and the controls can be linked via software.
400-X Feedback Control Loader System can be used with our 300-X Feedback Control Loader System and our full Motion Base Platform product line to make a comprehensive and cohesive system for simulation training.
All systems come with a full one year warranty and lifetime email/phone technical support. For more information on our warranty, please click here. Extended warranties are available.
Standard Specifications for 400-X Systems include:
Force at Pushrod is 1000 Lbs max, 500 Lbs continuous (other available)
Velocity at Pushrod is 25in/sec
Actuator Stroke is 5in max, 4in usable
Actuator Bandwidth is 100Hz or greater
Iteration Rate is 4000Hz or better
Latency (Ethernet) is less that 1ms
Analog to Digital Converter is 16-bit high speed
Digital to Analog Converter is 16-bit high speed
Flight Control Model:
Coupled mass system. Model includes cable spring, coupled mass, friction, damping, aero hinge moment, aero damping, boost actuators, non-linear gearing, breakout, centering spring, for and aft stops (fixed or movable), trim, autopilot engage, weight on nose wheel, nose wheel velocity and nose wheel velocity angle.
Control Parameters from Host:
Dynamic pressure, roll rate, pitch rate, yaw rate, dynamic pressure divided by velocity, boost oil pressure, autopilot command, autopilot engage, weight on nose wheel, nose wheel velocity and nose wheel angle.
Variables to Host:
Stick positions, Pedal position, Surface positions, control forces, nose wheel angle, nose wheel force, error code. Others available upon request.
Several interfaces are available: Bit 3, Ethernet, DR-11W (Concurrent), HSD (Encore), and UBC (Universal Bus Controller, Harris). Bit 3 is the easiest to use, Ethernet is the lowest cost for hardware. RS-232 can be used but is usually too slow. DR-11W, HSD, and UBC are essentially obsolete and should only be used with older host computers.
