Acoustics facilities in FL
4 facilities
Acoustic Test Facility
Panama City, FL
This facility consists of an oval, freshwater pond, which measures approximately 240 by 145 feet, and is 20 or 30 feet deep depending on the work area. There is a main building on land with a 100-foot covered test pier and a pontoon barge with an equipment building. Both buildings are instrumented with digital acoustic measuring systems consisting primarily of Hewlett Packard equipment. The measurement system in the main building is transitioning to a VXI data acquisition system. Rotating positioners, capable of handling 1,000 pounds, are located at both test sites, as well as 1-ton overhead hoists. Vinyl plastic liners are suspended beneath both the pier and the barge to provide clear, isothermal water in the work areas. Their dimensions are 38 feet long by 20 feet wide by 20 feet deep at the pier, and 45 feet long by 33 feet wide by 30 feet deep under the barge. Both liners extend to the mud bottom of the pond.
Physical Acoustics and Special Projects Laboratory
Panama City, FL
The tank is 10 ft long by 10 ft wide by 6.8 ft deep. Two positioning arms, located above the tank and computer controlled by stepper motors, are used to mount and provide precise location of transducers and targets in the tank. The positioning arms also allow clockwise and counterclockwise rotations. Attached to the side of the tank is heater with feed-back circuitry. This heater allows for measurements to be made as a function of water temperature in a range from ambient to over 40 degrees Centigrade. The measurement process is all digital and precise data collection can be computer controlled. A frequency range of 20 kHz to 3 MHz is available. Instrumentation for acoustic measurements includes: numerous transducers, computers, functional signal generators, waveform recorders, spectrum analyzers and filters.
RF Anechoic Chamber
Eglin AFB, FL
The J-PRIMES anechoic chamber provides a controlled, isolated environment. It can be used to simulate a variety of in-flight conditions, including electromagnetic interference / electromagnetic compatibility (EMI/EMC). The chamber can house a completely suspended and isolated F-15 aircraft, and has a direct fiber-optic link to the GWEF (Guided Weapons Evaluation Facility). Additionally, jammer signal simulation is provided.
Submarine Passive Acoustic Analysis Trainer
Orlando, FL
Depending on selected instructor setup options, the trainer shall have the capability for instructing "groups" of students utilizing the same scenario (Lockstep Mode), or for each student to be assigned a unique scenario (Independent Mode), or a combination of the two. In either case, actions performed by each student are completely independent of the other student stations.
