StallBox® is an industry-proven hardware and software solution designed to provide airlines and training centers with the stall models and instructor displays necessary to conduct Upset Prevention and Recovery Training (UPRT).
The StallBox solution minimizes computational and schedule impacts on the host device by off-loading flight model execution to an external computer that communicates with the existing host simulator system.
Using a single model, one can quickly acquire the aerodynamic data necessary for calculating all the full-scale subsonic vehicle motions realized in all flight regimes, including stall and post-stall flight. Force and moment as well as pressure data can be measured in static, body-axis oscillatory, and wind-axis rotational motions at all angles of attack, sideslip, oscillatory and rotational rates theoretically attainable by a vehicle.
Bihrle Applied Research, Inc. (BAR) is a premier aerospace technology firm providing advanced data, simulation, and analytical solutions to the global civil and defense aerospace sectors. As a U.S.-owned small business headquartered in Hampton, Virginia, BAR leverages decades of technical expertise alongside its wholly owned German subsidiary, Bihrle Applied Research GmbH, which operates an advanced wind tunnel testing facility. Since 1973, BAR has delivered innovative engineering and research solutions that have advanced both manned and unmanned aviation capabilities, enhanced commercial flight safety, and contributed to the design and validation of next-generation aerospace flight systems.
Customers worldwide rely on BAR for expertise and support in three core areas:
1. Aerodynamics Data – BAR is a recognized leader in the sourcing of comprehensive aerodynamics data sets, utilizing a variety of methods, including fixed-wing and rotary-wing flight testing, wind tunnel testing, and computational software tools to quantify complex aerodynamics behaviors across the full flight envelope.
2. Modeling & Simulation – BAR delivers high-fidelity aircraft flight dynamics and subsystem models to OEMs, research institutions, and training organizations. These models support a wide range of pilot training, engineering, and analysis applications throughout the aircraft development life cycle, from concept development through operational deployment.
3. Analyses – BAR offers specialized expertise in aerodynamics, stability, and control analyses. These services support the design and evaluation of new or modified aircraft configurations, assessment of stall, spin, and departure characteristics, and validation of simulator systems.
While BAR is an AS9100-certified company recognized for its technical excellence, it also maintains the agility and responsiveness of a small business.
