Capehart B housing units to close: Here's why By Capt. Stan Dou2lass NAWSCommonding c5rftcer to our Navy and our members. I want to take this opportunity to explain some very significant changes that are occurring in our housing program here at China Lake. It is an important issue, because it personally affects many ofour base residents, and because we must begin implementing this program now. These changes include the closure of Capehart B and assignment of E-5 and below military personnel to Capehart A. However, no current residents will be required to move off Station. You may ask, "Why does this need to happen now?" As many of you know, the Department of Defense budget appears to be stabilizing at about $250 billion per year, of which the Navy's share is approximately one- third this amount. This restrained budget authority has made it difficult for the Navy to sustain all its operations (including training, flying hours, at-sea exercises, etc.) while still allowing funding for research and develop- ment efforts and new weapons systems like the F/A- 18EIF and the Joint Strike Fighter. This has required the Navy to make difficult choices and to prioritize all aspects of its funding to ensure we maximize the benefit We must also, therefore, review our cost of doing business here at China Lake, including the amount we spend on married family housing. This year we are spending $7,680,000, or approximately $14,800 per base house, to support our 519 homes. By comparison, the cost in BAQ and VHA to house our married residents off-base would be approximately $3,237,000 per year, a very significant difference of over $4 million per year. When these financial aspects are related to critical Navy housing shortages that exist in some areas, such as the P lease see HOUSING, Page 8 THE ROCKETEER THURSDAY, JUNE 12, 1997 Ground broken for new mixer control room at Salt Wells plant Move allows processing to transition from 'black magic to science' By Gordon Fawkes Foctlth9$ Equipmenl ond Space Office 'This is not something we do every day," said John Robbins, head of the Airframe, Ordnance and Propulsion Division. "It's a challenge for the workers." He was referring to the con- struction of a new intermediate mixer control room at the Salt Wells Pilot Plant. The Ordnance Processing Section operates several propellant mixers and two curing ovens clustered together in the Pilot Plant. The mixers have capac- ities of one, five, 30 and 50 gallons, and the controls for the mixers are in very old, separate control rooms close by each mixer. "Process controls are outdated, unreliable and do not meet the precision or data requirement demanded by today's customers for propellant or explosives development," explained Robbins. If an explosive incident were to occur, the old control rooms would not protect operators from blast overpres- sures. "Any plan to modernize and upgrade the controls triggers current safety standards for protection of per- sonnel much like an addition to an old house must conform to current building cedes," said project manager Mike Heseman.

Some ofus even relish the prospect of a joint venture between government facilities. But an equal teaming effort between government employees and those from industry right from the start? Egads! That's about as scary as jumping into the Grand Canyon with only a bungee cord tied around your waist. A handful of our engineers, however, recently took the plunge by teaming with employees from Texas Instruments {TI), Inc., ofDallas, Texas, to pro- duce a low-cost ball- joint-gimbal infrared seeker, a planned tran- sition for the Joint Standoff Missile (JSOW) in FY 2002. China Lake's team members were Don Quist, Don Christison, Carl Zorzi, Brian Wolfe, Phil Bowen, Randy Coleman and Bill Wight, of NAW- CWPNS Signal Processing and Control Integration Section. concept feasibility, Quist assembled a crude prototype from spare parts in the lab. Quist says that to minimize costs, he fol- lowed the classic "KJSS" (keep it simple, stupid) principle. Without gyros, wires or precision parts, the ball-joint-gimbal design replaces the conventional mechanical gimbal with an electronic gimbal: motion, pitch and yaw are measured in the signal processing. Cost studies show that a high-performance infrared seeker using ball-joint-gimbal technology could be pro- duced for 50 percent less than the current seeker planned for JSOW. Mike Lloyd, a pro- gram manager for TI, says, "The arrangement KISS-Don Quist, of the NAWCWPNS Signal Processing and Control Integration Section, says he kept the new seeker's prototype design simple. The seeker's design and operation resemble an organ familiar to all of us: our eyes. A dia- mond-turned mirror "sees" the target. Its pivoting movement is aided by a mechanical ball and joint and four Kevlar lines. These lines, which function in a manner similar to the muscles that orchestrate eye movement, are attached to four separat~ motors. Conventional seekers use expensive encoders to directly measure the angle of the lens off the missile axis. Ball-joint-gimbal technology uses a dif- ferent approach. A low- cost shaft encoder is attached to each motor to measure the angle of was very unusual for our company; it involved a great deal of trust. Our teaming approach was very successful because we established a strong technical base at all levels and encouraged communication at all levels." "We were in each others' knickers constantly," China Lake's Quist says on the day-to-day teaming approach. The seeker, fLTst proposed in 1994 by Quist, got its start with $200K from the now defunct Apollo Program. To demonstrate the motor. These measurements are used by the signal-process- ing algorithms to calculate the angle of the mirror and compute the proper lengths of the Kevlar lines. Line lengths are adjusted by the four motors, which change the angle ofthe lens. The result of this unique design is a seeker with a large field of regard and a fast slew rate - 1,000 degrees per second.
