Industry Related News: United States – June, 2020:

Tenacity is the first space-worthy craft in the Sierra Nevada Corporation’s Dream Chaser line of spaceplanes, and they have just announced the latest addition to its design. The team at SNC has developed Thermal Protection System (TPS) tiles in order to protect the craft on its travels, mainly during the reentry process. With the ability to protect the structure from temperatures up to 1,650°C (3,000°F), these 10 sq. inch TPS tiles are integral in Tenacity’s launch and return. The tiles are white, allowing them to reflect heat from the sun and keep the craft at a manageable temperature of 176°C (350°F). The crucial components of the Tenacity require consistent and reliable protection from the elements to ensure that all functions are executed properly, which is why the security and effectiveness of the TPS plates remain a high priority during this development.

The 2,000 tiles protecting Tenacity will be attached to the exterior using room temperature vulcanizing (RTV) silicone, which is able to withstand high temperatures while keeping the tiles secured. The RTV silicone has been tested at extreme temperatures to measure its efficacy while enduring strength tests with mechanical pulling simulations to ensure the security of these important tiles. Thermal vacuum tests are effective forms of thermal testing, especially for conditions as dangerous as the Earth’s atmosphere.

The SNC team has already introduced durable heat-proof engineering with the frame of the Tenacity, which utilizes the most advanced high-temperature composite spaceframe in the industry. The combination of the protective TPS tiles, the resilient RTV silicone, and the advanced composite frame sets the Tenacity spaceplane for a safe voyage when it launches on United Launch Alliance’s Vulcan-Centaur rocket in 2021.

RF, Microwave Thermal testing

Controlling temperature with precision at the device case is a major benefit of the Khoury Box thermal test fixture. The DUT is isolated in a localized enclosure (at temperature) with the thermal air circulated around the device under test or DUT. Tester interface utilizes impedance-matched connections to ensure true and accurate test signals between the tester, the thermal test fixture, and the DUT.
