Model 300-X Feedback Control Loader System was designed for new flight control systems and to replace of spring type systems in existing systems. It has the advantage over spring type systems as it can be customized and trimmed out for each particular application and aircraft. This system is typically lower in cost than a mechanical spring type system with better fidelity. Model 300-X feedback control loader systems have a flight control model working with a Host or work in conjunction with MS Flight Simulator, Prepar3D or X-Plane.

The 300-X Feedback Control Loader system utilizes modified Helical gearboxes coupled with AC motors utilizing a closed servo loop to control the system for smooth and reliable performance. The gearbox has been modified to reduce backlash to a minimum, but some minor friction and inertia is reflected into the flight controls (see table below). This system was primarily designed for FAA Level 1 through 6 flight trainers. These systems have been certified for use in CRJ/737/A320 and Robinson R22/R-44Trainers up to FAA level 6.

Modular electronics coupled with a computer system and minimum cabling insure ease of installation, minimum maintenance and longevity. All parts are COTS and have been modified for use in this application. 300-X Feedback Control Loader System can be used with our 400-X Feedback Control Loader System and our full motion base platform product line to make a seamless, comprehensive and cohesive system for simulation training.

300-X is completely customizable for a variety of output torque requirements (refer to the table below). This allows for the same type of system to do a larger variety of controls  - all without having to rework documentation and engineering across multiple systems.

Flight Control Software Model:

The software model is based on the flight model provided with centering springs added if required. The model is designed so that it can be tuned from the Host, thus it could be used for any light aircraft or transport. Except for setting the scale factors for position and force, this model will not need to be tuned to each specific application.

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.

Safety:

The safety system in the control loader monitors the output to the DAC that drives the electronics. Monitoring the DAC allows the safety software to abort the system if the command to the electronics is excessive. In addition to the analog variables monitored by the safety software, the enable to the electronics has a one-shot that must be continuously re-triggered by the software. Should the software halt for any reason, the one-shot will time out and the loader will abort. E-Stop safety switches can be utilized for a mechanical abort.

Interfaces:

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 for some applications. Ethernet is typical.

Options:

This system can provide a nose wheel steering simulation, trim, tiller, throttle and a seat shaker option. Auto-Pilot integration is available upon request.

Power Requirements:

115 (230) volts, 7 (3.5) amps peak per axis

115 (230) volts, 1 (0.5) amps quiescent per axis

115 (230) volts, 3 (1.5) amps for the processor
