Joining Silicon Carbide Components for Space Propulsion

Phase 1 SBIR

Agency: National Aeronautics and Space Administration
Topic: 10-1-S3.04
Budget: 01/01/11 - 12/31/11
PI: Dr. Ender Savrun

This SBIR Phase I program will identify the joining materials and demonstrate the processes that are suited for construction of advanced ceramic matrix composite (CMC) thrusters for advanced monopropellants and bipropellants for space propulsion. We will join CMCs to each other and to superalloys by brazing. In Phase I, we will experimentally ...

Aluminum Nitride Based Absorber Materials for Toom and Cryogenic Temperatures

Phase 1 SBIR

Agency: Department of Energy
Topic: 44 A-2011
Budget: 01/01/11 - 12/31/11
PI: Dr. Ender Savrun

Currently available Aluminum nitridesilicon carbide (AlNSiC) composite lossy dielectrics are not suitable as high order mode (HOM) absorbers in superconductor radio frequency (SRF) cavities in linear accelerators operating at cryogenic temperatures. Even though they have favorable dielectric properties at room temperature, AlNSiC composites beco...

A High Performance Cathode Heater for Hall Thrusters

Phase 2 SBIR

Agency: National Aeronautics and Space Administration
Topic: 09-2
Budget: 01/01/09 - 12/31/09
PI: Dr. Ender Savrun

The current state-of-the-art co-axial swaged tantalum (Ta) heaters use magnesium oxide (MgO) insulators, which limits their operation to temperatures well below 1300ýýC to prevent undesirable chemical reactions between Mg and Ta and heater failure. This program will develop a new ceramic insulator that is chemically compatibility with Ta and ...

Infrared Transparent Zero Thermal Expansion Ceramic

Phase 1 STTR

Institution: University of Washington

Agency: Navy
Topic: N08-T003
Budget: 07/14/08 - 02/14/09
PI: Ms. Stephanie Sawhill

This program will develop a single-phase cubic material with near zero thermal expansion and high (>80%-85% in-line) infrared transmission from 3 µm to 5 µm for infrared domes and windows. The low thermal expansion material will have high thermal shock resistance as well as good mechanical strength to survive harsh environments. In this Phase ...

Phase 1 SBIR

Agency: Air Force
Topic: AF081-061
Budget: 06/07/08 - 03/10/09
PI: Ms. Stephanie Sawhill

In this Small Business Innovation Research (SBIR) program, a high throughput chemical micropropulsion system for nano- and microsatellites will be developed. The microthruster will use an all-ceramic construction to withstand the high temperatures associated with the high Isp, clean burning, high-energy-density, non-toxic liquid monopropellant....

High Performance Lossy Dielectric HOM Absorbers for SRF Cavities

Phase 2 SBIR

Agency: Department of Energy
Topic: 2008
Budget: 01/01/08 - 12/31/08
PI: Dr. Ender Savrun

Recently developed high thermal conductivity aluminum nitride (AlN) based lossy dielectrics can replace the toxic beryllia (BeO) based lossy dielectrics as high order mode (HOM) absorbers in superconductor radio frequency (SRF) cavities in linear accelerators and in microwave tubes. AlN-based lossy dielectrics must be joined metallic copper memb...
