5/24/93: NASA SYSTEM RESEARCH AIRCRAFT MAKES FIRST TEST FLIGHT

RELEASE: 93-95
A NASA F/A-18, specially modified to test the newest and most advanced
system technologies, made its first research flight on May 21 at NASA's
Ames-Dryden Flight Research Facility, Edwards, Calif. The Systems Research
Aircraft (SRA) is evaluating technologies that will benefit both civilian and
military aircraft.
"The SRA systems testbed aircraft is a faster, better and cheaper
approach that lowers systems development cost and cuts the time needed to
develop new technologies," said Denis Bessette, Project Manager at Dryden.
"This project will help ensure that new aerospace concepts are transferred to
U.S. industry to accelerate transition of those advanced technologies."
The plane's first mission involved tests of an electric actuator that
has two small computers to monitor the position and control of one of the
aircraftUs ailerons. An actuator takes signals from the aircraft's flight
control computer and translates them into mechanical actions that move control
surfaces such as flaps, ailerons and rudders. The "smart" actuator being
tested needs less wiring and should have better performance and reliability
than the mechanical actuators now in general use.
The second program scheduled for the aircraft will investigate the use
of optical systems on future aircraft. Fiber optic cable is lighter, carries
more signals and is resistant to interference from strong radio signals and
lightning.
NASA and industry are working on fiber optic sensors to measure the
position of aircraft control surfaces, pilot input to the controls, engine
temperatures and other aircraft and engine functions. The measurements from
these optical sensors will be compared to the standard aircraft sensors to
obtain information on how well the optical systems perform.
A third program will develop a new way to measure an aircraft's speed,
altitude and other air data parameters. The method to be tested has no moving
parts which will increase accuracy and reliability. Unlike traditional air
data sensors which protrude into the airstream and produce drag, the new system
uses several flush ports arranged around the tip of the planeUs nose.
The advanced actuator program is a joint effort by Ames-Dryden, the
U.S. Air Force and the U.S. Navy. The fiber optic research program is a joint
program by Ames- Dryden and the Lewis and Langley Research Centers. The air
data system studies are a NASA-industry cooperative program with Honeywell and
McDonnell Douglas Corp.

NASA managers have set June 3, 1993, as the target date for the upcoming STS-57
mission. Endeavour and her six person crew will conduct a mission highlighted
by the retrieval of the European observation satellite EURECA. This mission
will also be the first flight of the commercial spacelab facility, Spacehab.
The mission is planned for 7 days and 23 hours with the possibility of a 1 day
extension immediately after launch if projections calculated at that time for
electrical power consumption permit an extra day in space. If the extra day is
permitted, crew members will have the opportunity to perform an extravehicular
activity (EVA), or spacwalk. The launch window extends from 6:17 to 7:28 p.m.
EDT with launch scheduled for 6:17 p.m.
Technicians at the Kennedy Space Center plan to purge the external tank,
conduct a helium signature test and do hypergolic purges to continue to prepare
the Space Shuttle Endeavour for the mission.

NASA will exhibit at the 40th Paris Air Show a 50- monitor videowall June 10 -
20. This year's theme, "A New Age of Exploration--Expanding the Frontiers of
Air and Space for the Benefit of All," will acknowledge the many contributions
of NASA's international partners in human and robotic spaceflight and the
importance of continued international cooperation to meet the upcoming
challenges.
The video presentation features participants discussing space station, space
technology, space science, space exploration and aeronautics. Besides the
videowall, NASA will exhibit a new 10-foot High Speed Civil Transport aircraft
model, a Pratt and Whitney mixer- ejector nozzle, and a high altitude Perseus
model. The exhibit also will present NASA's work to develop technology for a
new generation of supersonic airliner.

NASA officials will conduct a press briefing Wednesday, May 26 at 1:00 p.m.
EDT to discuss the Magellan spacecraft's aerobraking maneuver and recent
gravity findings at Venus.
The press briefing will include a status update on the aerobraking experiment
and a release of photos and a video from Magellan's gravity studies during its
fourth orbital cycle.
NASA TV will broadcast the briefing live and two-way question-and-answer
capability will be available at JPL and other NASA centers.
