The Boeing Large Core Arc Tunnel (LCAT), a provider of high-temperature testing services, is the only commercial arc-jet facility in the United States. It has a long history of designing and conducting a wide variety of tests.
The LCAT arc-jet facility supports the development of heat shield and temperature-resistant materials for spacecraft and advanced weapon systems and can accommodate wedge and stagnation test requirements.
The laboratory uses the MDC-200 Huels-type arc heater, which features a high-pressure design that provides extremely reliable service. Normal direct-current power input to the MDC-200 is variable from a few hundred kilowatts to approximately 5 megawatts. A variety of supersonic nozzles can be fitted to the MDC-200 arc heater to provide different test environments.
A secondary test site houses the T58 Hot Gas Generator, a small gas-turbine engine that provides moderate temperature flow environments for evaluating materials and thermal control schemes in a turbojet-type exhaust environment.
