Philtec Provides Solutions for Outer Space Applications
Aerospace sensor applications are among the most demanding in the world. Philtec sensor systems have been successfully engineered into these extreme environments:
- Pressurized Cryogenic Fluids – LOX, LN2, CH4
- Extreme Temperatures – down to 4°K and up to +400°C
- Ultra-High Vacuum
- Strong Vibrations
The wide range of applications using Philtec’s sensors include:
- James Webb Space Telescope — Philtec sensors & vacuum passthru hardware were used to measure displacements of critical components of this telescope as they were brought down to the cold temperatures of outer space.
- Rocket Turbopumps — Propulsion engineers are using Philtec Fiber optic sensors to measure radial and axial rotor displacements and rotational speed of rocket turbopumps using new fuels such as methane, propane and kerosene. Long fiber optic cables (45 – 60 ft.) keep the electronics away from the heat and vibration at the engine test stands.
- Space Shuttle — In the wake of the Challenger disaster, Thiokol engineers used Philtec sensors installed between the joints of rocket sections to determine how much separation occurred during firing, to help solve the O-ring leak problems.
- Space Shuttle — NASA’s MSFC used Philtec probes in a LOX pressurized cryogenic environment to monitor bearing deflections in the Space Shuttle Main Engine.
- Flight Tests — Philtec 90° tip sensors were used for Airbus 380 flight tests to measure displacement of thrust reversors.
- Turbine Applications — Philtec sensors have been used for various measurements such as speed of 1,000,000 rpm micro-turbines; shaft displacements, time-of-arrival and flutter in gas turbine and turboshaft engines. Wireless sensors have been used to measure cold clearance in large power gas turbines.
