Real Time Models

Overview

The FLIGHTLAB Development System is capable of supporting both fixed and rotary wing flight dynamics simulation but the emphasis to-date has been on supporting the more challenging area of rotorcraft simulation. Under an Army SBIR, ART combined the FLIGHTLAB environment and solution methodology with a comprehensive rotorcraft component library originally developed to support the Government’s Second Generation Comprehensive Helicopter Analysis System (2GCHAS). The resulting program, named the Rotorcraft Comprehensive Analysis System (RCAS), has become the Army’s standard for rotorcraft engineering analysis. Under a CRADA between ART and the Army’s Aeroflightdynamics Directorate (AFDD), ART has agreed to support RCAS as a nonproprietary Government tool and the Army has agreed to support ART in developing a library of Army rotorcraft models for RCAS that can also be ported to the real-time FLIGHTLAB environment, due to the commonality in the simulation language. The Aviation Engineering Division (AED) at the Army’s Redstone Arsenal has worked with ART to create a library of Army rotorcraft models for the FLIGHTLAB/RCAS environment and ART has transitioned these models into Army training simulators. Under the AVCATT program, ART is providing flight dynamics models of the UH-60A/L, AH-64A/D, and OH-58D. Other models developed jointly with AED include the RAH-66 Comanche and the CH-47D Chinook. ART has also modeled the TH-67, UH-1 and OH-6 Army
helicopters.
ART has also entered into a CRADA with the Navy’s Manned Flight Simulator (MFS) at the Naval Air Warfare Center Aircraft Division, Patuxent River , MD , to integrate FLIGHTLAB models with their CASTLE host software. Under this agreement the MFS has supported ART in developing a blade element model of the V-22 and ART is integrating it with the V-22 simulator at MFS for applications requiring comprehensive modeling, such as shipboard landing. ART has also developed SH-60 and AH-1W models for Navy applications. Under the LSHIP program, ART is integrating a UH-60L model with shipboard landing capability into the Army’s UH-60 Operational Flight Trainer (OFT) at Ft. Campbell to demonstrate the training potential.
