The NTS Indianapolis test facility has been operating since the 1940’s and in its current location since 1990, becoming a division of NTS in 2010.
The Indianapolis division provides an extensive array of mechanical and pneumatic services. With more than 25 years of experience, our engineering staff has the expertise and know-how to service the needs of clients in both the Defense and Aerospace sectors.
Other test experience at NTS Indianapolis includes:
NTS Indianapolis is able to perform a variety of structural, environmental and functional testing. Test capabilities include, but are not limited to wind/hurricane simulation, rain, water and waterjet spray, cold climate start simulation, valve hunting/cycling, leakage, check valve operation in the flow and no flow directions, solenoid operation in cold and hot climates, vibration and classical shock, transportation drop shock, hydrostatic/hydraulic proof and burst pressure, and burst to failure testing.
Heat transfer testing is also known as heat rejection or thermal performance testing. Heat transfer testing involves products which transfer or dissipates heat from one source to another, such as heat exchangers, cold plates, and heat sinks.
Heat transfer testing involves the measuring the mass flow of a fluid and the change in temperature of the fluid between a designated inlet and outlet. The heat energy per a unit of time can be calculated from this information. A positive or negative change in termpareature indicates if the fluid stream is releasing or gaining energy. Typically there are at least two fluid streams involved, since heat energy must be passed from one fluid stream to another. The fluids can be either liquid (ie: oil, hydraulic fluid, water/glycol, jet fuel, etc.) or gas (ie: air, nitrogen, etc.). Temperatures of the fluids and ambient conditions can be altered to simulate operation in arctic climates (-65°F) or operation in dry, desert conditions (135°F). Gas testing can be performed up to temperatures of 1,250°F, simulating bleed air, exhaust gases, turbine output and other similar applications.
These items are used in a variety of systems and products in a wide array of market sectors, some examples are:
Pressure Drop testing typically goes hand-in-hand with Heat Transfer Testing, though there are other products and applications for this type of testing separate from Heat Transfer. Pressure Drop testing involves measuring the fluid flow through a product, the inlet/outlet temperature, and the inlet/differential pressure. In addition to the products listed above, this also includes valves, filters, regulators, and other components in a fluid flow stream. In relation to valve testing we can gather data and calculate the CV factor of a valve for various fluids. For filters, an emerging technology is efficiency testing. We are developing capability in this area and can provide this service.
Thermal cycle testing can take many different forms, depending on the product. In relation to heat exchangers we can generate changing flows and temperatures for the fluid circuits to cycle applied thermal stresses on a product. For thermostatic valves, we can alternate hot and cold fluids to cause the valves to cycle between no stroke and full stroke. These items are similar to thermostats used in automotive cooling systems.
