Honeywell Aerospace

Supercritical fluids were identified in early 1989 as a possible CFC replacement for certain niche applications at Honeywell Space Systems. At that time there was very limited data on either the application of supercritical fluids for precision cleaning or compatibility studies with materials common to the aerospace industry. 

Continued demonstration of a modified turboeompressor with increased turbine inlet temperature (315°C) capability and aerospace quality variable speed brassboard motor controller in the 50-kW DOE/Honeywell fuel cell brassboard system. 

To support the DOE/Honeywell fuel cell brassboard system testing, the turbocompressor was modified to handle increased turbine inlet temperatures. In addition, a modified aerospace quality motor/controller was assembled and used in the DOE/Honeywell fuel cell brassboard system, replacing a previously used motor/controller commercial unit. Testing of the DOE/Honeywell fuel cell brassboard system was initiated in late 2000 and is expected to be completed in mid 2002. 

LMA designed and developed the flight control software, while Honeywell was responsible for the Inertial Measurement System (IMS) software. This separation of control, combined with poor coordination, accounts for some of the problems that occurred. Analex was the independent verification and validation (IV V) contractor, while Aerospace Corporation provided independent monitoring and evaluation. Ground launch operations at Cape Canaveral Air Station (CCAS) were managed by the Third Space Launch Squadron (3SLS).
