“We Freeze to Please” throughout industry and government. Hundreds of engineers use the LEWICE ice- accretion modeling code, and the FAA now accepts it as part of their icing certification process. NASA continues to improve these codes and verify them against experimental data. Because of our close ties with the European icing community, they too are familiar with LEWICE and our other codes—a favorable situation for those U.S. airplane man- ufacturers who must certify their products in Europe. Although we developed several new ice-protection and ice-detection concepts early on, mainly through SBIR contracts, industry did not adopt any initially. But after I retired and Tom Bond became the branch chief, his team succeeded, via an SBIR con- tract, in getting a new aircraft ice-protection system approved by the FAA in 2001. It was the first new ice-protection system approved by the FAA in 40 years! The system, built by Cox & Company, Inc., New York, NY, is a hybrid that uses both thermal anti-icing and electro-mechanical expulsion de-icing. The system is adaptable and uses much less energy than other systems that provide equivalent protection. The system is in produc- tion for Raytheon Aircraft’s Premier I business jet. Another internationally recognized contribution of Tom Bond’s branch is pilot edu- cation for improved flight safety in icing conditions. NASA has made three pilot training videos and one training CD (compact disk). These widely distributed videos and CDs address the icing environment, flight preparedness and strategies for avoiding icing con- ditions, stall due to tailplane ice, and loss of control due to wing ice. According to Tom Bond, “The tail stall recovery techniques developed in the Tailplane Icing Program have resulted in averted accidents and saved lives. NASA has received numerous accounts of pilots who have used these operational procedures and successfully prevented a loss of control due to a tail stall.” For 10 years, Tom Ratvasky has been the technical program manager and lead flight research engineer on NASA’s icing flight research aircraft. The American Institute of Aeronautics and Astronautics recognized Mr. Ratvasky’s leadership in conceiving and producing these instructional materials by awarding him the prestigious 2002 Losey Atmospheric Science Award. I believe that we can say with pride that the “new” aircraft icing program at Glenn Research Center has continued the tradition of the “old” program by contributing valu- able technological and safety support to the aircraft industry. One final note: the title of this book, “We Freeze to Please,” was the brainchild of Mr. Al Dalgleish, a branch chief in the Test Installations Division. He used to answer the telephone by saying “Icing Research Tunnel, where we freeze to please.” Besides being a play on words, it was Al’s way of saying “we will cooperate with you to get your job done.” The “We Freeze to Please” logo made its way onto the IRT baseball caps. Nearly everyone who tested in the IRT went home with an IRT baseball cap. Visitors from other countries took them home. The logo sent the message far and wide that the IRT staff was viiiPDF Image | History of NASA Icing Research Tunnel
