66 -- FLIGHT CONTROL ACTUATOR TEST STATION (FCATS) SOL N00421-96-R-1089 DUE 073196 POC Anne C. Brown, (2611AB) Contract Specialist, (301) 342-1825 ext. 118. The Naval Air Warfare Center Aircraft Division (NAWCAD) has a requirement for a Flight Control Actuator Test Station (FCATS) dedicated for flight control testing. FCATS will support NAWCAD's Air Combat Environmental Test & Evaluation Facility (ACETEF) Manned Flight Simulator (MFS) Flight Control Branch to perform the testing of any actuator (electromechanical or electrohydraulic) in the United States Navy aircraft (fixed and rotary wing) inventory. This procurement for FCATS is separated into a baseline system and options. The FCATS baseline system shall have, but not be limited to, the following main elements: (a) Hydraulic Power Source and (b) Actuator Test Stand. The FCATS baseline system shall meet the requirements stated for the baseline system and shall provide growth for all of the requirements listed in the options. The FCATS system level requirements are, but not limited to, the following: (a) FCATS shall be designed with emphasis on ease of use, modularity and versatility, (b) FCATS shall operate in two modes, Stand Alone Mode and In-The-Loop Mode, where the time and effort required to reconfigure between the two modes shall be minimized. 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 through conventional analog loop closure methodology (a standard interface shall be implemented in FCATS to allow for ease of breadboarding of actuator drive circuitry). 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 aircraft Flight Control Computers (FCC's), (c) FCATS shall provide a patch panel for the easy interruption, removal and changing of signals/equipment. The FCATS Hydraulics Power Source shall have the following attributes: (a) up to and including 5000 psi operation, (b) two separate hydraulic channels (two separate sources or one source with two separate pressure 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 controllable and measurable flow rates for all actuators under, and (g) sound isolation from the rest of the facility. 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 (as described in the options) during testing. The FCATS options shall be categorized, but not be limited to, the following main parts: (a) Hydraulics Power Source Options, (b) Actuator Load Fixture Options, and (c) Computer System Options. The Hydraulic Power Source Options shall include, but not be limited to, the following attributes: (a) Electrical Control of Pressures, (b) Electrical Control of Flow Rate, (c) Electrical Control of Hydraulic Fluid Temperature, (d) Basic Control of Hydraulic Fluid Temperature. The Actuator Load Fixture shall have the following: (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 Options are separated into a baseline option and dependent options. The Computer System Baseline Option shall have, but not be limited to, the following attributes: (a) programmable graphical user interface, (b) hardware and software required to monitor all activities with respect to the actuator under test, and (c) enough growth capability to implement the following Computer System Options. The Computer System shall have, but not be limited to, the options: (a) data analysis capability that shall include, but not be limited to, strip charts, model generation, and phase and gain plots, (b) hardware and software required to perform functions of hydraulics system monitoring and control, (c) hardware and software required to perform functions of load fixture monitoring and control, (d) hardware and software required to perform functions of actuator control. Loop closure shall be performed by digital means - where analog uses conventional loop closure methodology of analog circuitry, digital (in this case) uses loop closure through a relatively high throughput computer system and shall utilize algorithms designed using software such as, but not limited to, Simulink or Matrix X, (e) hardware and software required to interface to MIL-STD-1553B busses, (f) hardware and software required to interface to MIL-STD-1773 busses, (g) hardware and software required to interface to a Procuring Activity owned Applied Dynamics Real-Time Station (AD RTS). The government prefers equipment proven to be highly reliable and maintainable. The contract type will be firm fixed price. The FCATS shall be delivered to the Manned Flight Simulator, Building 2035, Naval Air Warfare Center, Patuxent River, MD one year after contract award. Requests for copies of the solicitation must be submitted in writing. Requests may be faxed to (301) 342-1864 to the attention of Ms. Anne C. Brown. All responsible sources may submit a proposal which shall be considered by this agency. (0177)
