AbstractThe primary work of Robert Heffley Engineering consists of support in the areas of flight simulation, modeling the pilot-in-the-loop, fixed-wing and helicopter math modeling, and handling qualities. During recent months we have supported various projects for Hoh Aeronautics, Inc., Boeing, Synetics Systems Engineering Corp, and our own internal product development.

During the past year we assisted Hoh Aeronautics, Inc. in their development of the ADS-33E Specification Application Package (ASAP). This package is intended to aid the ADS-33E user in configuring a tailored design requirement for helicopters, handling supporting test data, and performing required analysis. ASAP currently runs as a set of Matlab GUIs that will eventually be configured as a standalone application.

Another recent project consisted of supplying several RotorGen2 helicopter math models combined with inner-loop-control pilot models for use in Boeing's NetForce training simulator system. Their training system is used for examining tactical missions and flight scenarios involving multiple aircraft and pilots. NetForce users are able to execute mission task elements and maneuvers directly without concern for inner-loop control which is supplied by RHE Task-Pilot-Vehicle (TPV) models.

Both RotorGen2 and TPV models have been used by Synetics Systems Engineering Corp in their design of an autonomous unmanned helicopter system as well as in the planning and execution of flight testing with a Bell 206 helicopter.

Finally, we have continued our own in-house development of RotorGen2 and TPV models for use with Simulink and FlightGear software. We now have a standalone RotorGen2 windows application that drives FlightGear visual imaging. Additionally, the existing Simulink/FlightGear s-function capability can now control a RotorGen2 helicopter model with an RHE-developed Simulink s-function. The result is a flexible non-linear helicopter simulation capability with image-generation from the cockpit or as an outside observer.

We continue to offer a variety of engineering services along with analysis and simulation tools for supporting our diverse customers.
