                         HON. JOHN T. DOOLITTLE

                             of california

                    in the house of representatives

                         Tuesday, May 20, 2008

  Mr. DOOLITTLE. Madam Speaker, I submit the following:
  Requesting Member: Representative John T. Doolittle.
  Bill Number: H.R. 5658.
  Account: Air Force--RDT&E, AEROSPACE PROPULSION.
  Legal Name of Requesting Entity: Aerojet-General Corp.
  Address of Requesting Entity: Highway 50 & Aerojet Rd., Rancho 
Cordova, CA 95742.
  Description of Request: An increase of $3,000,000 for Air Force RDTE 
Line Aerospace Propulsion for Hydrocarbon Boost Technology 
Demonstrator. The Air Force Research Laboratory (AFRL, Edwards AFB) has 
initiated a Hydrocarbon Boost Technology Demonstrator program to 
provide the United States with a liquid hydrocarbon rocket engine to 
power the next generation of launch vehicles for assured access of 
critical national security payloads. Instead of a hydrocarbon fuel, 
most American liquid engines in large thrust

classes use liquid oxygen and hydrogen propellants. Cryogenic hydrogen 
is costly to produce. It is also difficult to work with compared to 
hydrocarbon fuels due to its extremely low storage temperature 
requirement and launch operations safety concerns. Furthermore, the 
propellant properties and very cold temperatures reduce the life of the 
materials involved and make low cost, rapid turnaround reusable 
applications nearly impossible. Hydrocarbon liquid rocket engines 
ultimately derived from the advanced technology developed and 
demonstrated in the Hydrocarbon Booster Technology Demonstrator program 
will not only provide the highest performing hydrocarbon engines ever 
developed in the United States, but also will provide higher 
operability, lower costs and greater safety with higher reliability 
than any liquid booster engine ever made in the U.S. and perhaps the 
world. The funding would be used for Ox Rich Preburner and Turbopump 
concept designs.
