66 -- FLIGHT CONTROL ACTUATOR TEST STATION (FCATS) SOL N00421-96-R-1089 POC Anne C. Brown, Contract Specialist, (301) 342-1825 Ext. 118. This is a SOURCE SEEKING SYNOPSIS for the design, fabrication, delivery, and integration of a Flight Control Actuator Test Station (FCATS). THIS IS NOT A FORMAL PROCUREMENT AND THEREFORE THERE IS NO SOLICITATION. NOTE: THIS IS NOT A REQUEST FOR PROPOSALS. This sources sought is published as a market search for FCATS. FCATS is to support the Naval Air Warfare Center, Aircraft Division's (NAWCAD) Air Combat Environmental Test & Evaluation Facility's (ACETEF) Manned Flight Simulator's (MFS) Flight Control Branch in performing the testing of any actuator (electromechanical or electrohydraulic) in the USN aircraft (fixed and rotary wing) inventory. FCATS shall be designed with emphases on ease of use, modularity, and versatility. FCATS shall have, but not be limited to, the following main parts: (a) Sound Isolated Hydraulic Pump(s); (b) Actuator Test Stand; (c) Actuator Load Fixture; (d) Computer System. The FCATS hydraulics pump shall have the following atributes: (a) up to 5000 psi operation; (b) two separate hydraulic channels (two separate sources or one source with two separate prssure regulators); (c) separate control for the return pressures; (d) high pressure, high bandwidth pressure transducers for measuring of all pressures; (e) testing at hydraulic fluid temperatures up to 250 degrees F; (f) sufficient flow rates for all actuators under test. The FCATS actuator test stand shall have the following attributes: (a) collection of hydraulic leaks; (b) protection from hydraulic leaks; (c) support actuator under test; (d) support actuator load fixture during testing. The actuator load fixture shall have the following attributes: (a) sufficient loads for testing actuator under test; (b) sufficient stiffness for testing actuator under test; (c) generation of nonlinear loads; (d) dynamic variation of loads; (e) receive a load or hinge moment from simulation and produce that load at actuator connection; (f) high bandwidth at the high forces. The computer system shall have the following attributes: (a) hardware and software required to perform functions of actuator control, monitoring, data acquisition, and data analysis; (b) 'patch panel' to allow break-out of any signal; (c) loop closure through analog or digital means - analog uses conventional loop closure methodology of analog circuitry (a standard interface to FCATS shall be implemented to allow for breadboarding of actuator drive circuitry), digital uses loop closure through a relatively high throughput computer system by algorithms designed using software such as, but not limited to, Simulink or Matrix X; (d) sufficient I/O such as analog to digital converters and digital to analog converters and digital busses (MIL-STD-1553B); (e) programmable graphical user interface; (f) data analysis capability shall include, but not be limited to, strip charts, model generation, and phase and gain plots; (g) interface for communicating with the rest of the simulation facility; (h) FCATS shall operate in two modes, Stand Alone and In-The-Loop. The FCATS design shall minimize the time and effort required to reconfigure between the two modes. During the Stand Alone Mode, FCATS shall be isolated from the rest of the MFS facility. FCATS shall provide all required stimuli and control during actuator testing. During In-The-Loop Mode, FCATS shall operate as part of the MFS hardware-in-the-loop facility. The actuators shall be directly controlled (provided with control signals) by the aircraft Flight Control Computers (FCC's). The government prefers equipment proven to be highly reliable and maintainable. All interested parties should submit comments, capability statement, time to deliver, price estimates, and any other pertinent qualifications. This is only a Sources Sought Notice and not a solicitation. NAWCAD anticipates solicitation for proposals and contract award during FY96. This request is for informational literature ONLY AT NO COST TO THE U.S. NAVY. Please provide responses detailing proposed Flight Control Actuator Test Stations (FCATS) by 15 April 1996.
