VULCAIN FIX: Europe's big Vulcain rocket engine will be slightly modified to prevent a roll that caused the Ariane 5 launch vehicle to shut down prematurely after its first successful launch last year. Hot-fire analysis with a special roll torque measurement device attached to the test stand has pinpointed the cause of the roll as roughness on the inner surface of the engine nozzle, which imparted a slight spiral to the hot gas flow. According to the European Space Agency, the turbine exhausts will be repositioned to counter the phenomenon.
DIRECCION GENERAL DE AERONAUTICA CIVIL, Chile's air navigation service provider, the U.S. FAA and Raytheon Systems Co. will install a satellite navigation test bed reference station in Santiago and one in Balmaceda, Chile.

The Pentagon, acknowledging concern by the General Accounting Office, told the U.S. Air Force last week to convert the first two production F-22 fighters to be bought later this year to pre-production vehicles (PPVs). The GAO was worried that the production decision would be made before sufficient testing.
TRIPROPELLANT: Russia's Design Bureau of Chemical Automation (DBCA) will begin testing a tripropellant rocket engine this week that might hold promise for a single-stage-to-orbit reusable launcher. Vladimir S. Rachuk, DBCA general designer, says the engine is rated at a sea-level thrust of 120 tons, burning kerosene first and then liquid hydrogen, with liquid oxygen as the oxidizer. Based on the company's RD-0120 oxygen/hydrogen rocket, the new engine has been mounted in the test stand at Sergiev Posad, near Moscow, for its hot-fire test series.
The proposed acquisition of Northrop Grumman by Lockheed Martin will "benefit competition in military aircraft and defense electronics," not hamper it as the U.S. government has charged, the two companies argued in a joint response to the government's anti-trust complaint against the merger. In a document filed Friday in U.S. District Court for the District of Columbia, the two companies also argue their merger would "create annual savings of hundreds of millions of dollars by reducing overcapacity and increasing efficiencies of scale."
Launch of the first Earth Observing System satellite has been delayed until the end of the year because of bugs in the custom software written for the ground systems that will control, monitor and schedule science on the Earth science platforms, NASA reported Friday.
Raytheon Systems Co. has won a $17.9 million follow-on production contract from Delco Defense Systems Operations for thermal imaging and fire control systems for Canadian Army Armored Personnel Carriers. The contract brings the total number of Raytheon HIRE systems ordered for the program to 486 since the contract was awarded in October 1996.
SHORTFALL SEEN: The $20 billion in the fiscal '98 Pentagon budget for strategic nuclear forces should actually be about $22 billion, according to the Congressional Budget Office. It says the budget provides $2 billion for nuclear force modernization instead of the $4 billion the Pentagon has said it needs. The $20 billion, according to CBO, includes $8 billion for strategic offensive forces, $4 billion for Dept. of Energy programs, $6 billion for C3 and surveillance, and $2 billion for treaty verification and related items.
The first of 18 Block 52 F-16C aircraft for Singapore was delivered Thursday at ceremonies at Lockheed Martin Tactical Aircraft Systems in Fort Worth, Tex. "Today continues the long-standing relationship between our company and the Republic of Singapore Air Force," Robert T. Elrod, vice president of F-16 programs, said in a statement. "By continuing to inject modern technologies into the F-16, we have ensured that the aircraft being delivered today is the most advanced multirole fighter currently in operation."
Lockheed Martin worked closely with its Joint Air-to-Surface Standoff Missile subcontractors to reduce the cost of its winning bid, in one case cutting the price of a component used in its design and that of the losing Boeing design.
RAYTHEON SYSTEMS CO., Lexington, Mass., signed a contract with a potential value of $20 million with the Dept. of Civil Aviation, Jamaica, to provide modern radar approach control capabilities at Montego Bay and Kingston international airports. RSC also won air traffic control system contracts from the Dept. of Civil Aviation, Curacao, Netherlands Antilles and the Princess Juliana International Airport, St. Maarten, Netherlands Antilles.
KODIAK TESTS: The U.S. Air Force is said to be getting ready to present a proposal to the National Missile Defense Joint Program Office for NMD risk reduction missile tests from Alaska's Kodiak Island. NMD JPO Director Brig. Gen. Joseph Cosumano appeared disgruntled last month when Air Force Brig. Gen. James K. Beale, director of space and nuclear deterrence for the service's acquisition office, said the AF wanted to conduct tests out of Kodiak to support NMD. Cosumano said at the time that there had been no coordination with the NMD JPO.
ADVANCED TECHNICAL PRODUCTS, INC., reported that its Intellitec Div., Deland, Fla., has won a $3.6 million contract from Army Communications- Electronics Command to produce various configurations of radar-scattering camouflage systems and components. The initial production and testing is slated to start in the middle of this year, with production and deliveries to complete in 1999.
SRI LANKA placed a $150 million order with Rolls-Royce for Trent 700 engines to power six Airbus A330-200s scheduled for delivery beginning in October 1999. Air Lanka's new business partner, Emirates, also has ordered the engines for 16 of the aircraft, also due for delivery beginning in 1999, Rolls said.
The U.S. Air Force has restructured its Air Superiority Missile Technology program after funding cuts were incurred last year. The AF last year awarded Boeing - McDonnell Douglas at the time - a contract for the five-year ASMT program. But funding hits have prompted the service to break the activity into two programs and delay flight testing of a dual-range air-to-air missile by a couple of years. ASMT was to have demonstrated missile control technology on an Advanced Medium-Range Air-to- Air Missile (AMRAAM) airframe.
AlliedSignal Engines' new 131-9[A] auxiliary power unit for the Airbus A320 jetliner family has started flight tests on an A320 in Toulouse, France, AlliedSignal reports. "All major program milestones of the 24-month development schedule have been met on time and we have achieved all our intended design and performance objectives," says Tom Johnson, VP for commercial auxiliary power at AlliedSignal Engines. The -9[A] is available as an option for A319s, A320s or A321s slated for delivery after September 1998.
GLOBALSTAR LP has ordered $353 million worth of satellite telephones for initial users of the planned 48-satellite "Big LEO" low Earth orbit communications satellite system.

It's an 80-inch, aluminum-hub constant speed system designed to maximize low-speed thrust for improved acceleration and climb. Complete retrofit kits, including supplemental type certificate documentation, list for $7,195.
FAA wants operators of eight different Textron Lycoming recips - a fleet of some 19,000 engines - to remove potentially defective Superior Air Parts piston pins, following reports of pin fractures. Investigators discovered that Superior shipped pins between Aug. 24, 1993, through April 22, 1996, that "may contain subsurface manufacturing imperfections, such as higher impurity levels, retained austenite and grind burns," FAA says.
The critical Russian Service Module for the International Space Station, which has already pushed back the schedule for start of on-orbit assembly of the Station, will be another three to four months late, Russian space officials told a U.S. congressional delegation this week.
The Republic of China Air Force on April 7 accepted four search and rescue helicopters at Sikorsky Aircraft's facilities in Stratford, Conn. The new helicopters will join the ROCAF's fleet of 13 S-70C helicopters currently performing SAR missions in Taiwan.
