August 13, 1993 Linda Ellis Lewis Research Center RELEASE: 93-147 Icing studies, that may result in major improvements in predicting helicopter rotor performance in icing conditions, were recently completed in the Icing Research Tunnel at NASA's Lewis Research Center, Cleveland. A one-sixth scale Sikorsky Black Hawk helicopter model was tested for 10 weeks over a wide range of icing conditions and critical forward flight conditions. The tests by NASA, the U.S. Army and Sikorsky Aircraft, Stratford, Conn., were focused to expand the experimental database as well as develop reliable methods to reduce the cost and time required to certify civil helicopters for flight into forecasted icing. "The new experimental database resulting from these tests will be used to further refine and validate a computer code that Sikorsky and NASA developed in earlier testing," according to Thomas H. Bond, Project Manager at Lewis. The code predicts helicopter rotor performance loss occurring when ice accumulates on the rotors during an icing encounter. "We expect this computer code can be used to predict full-scale helicopter performance in icing after the code is further validated with full- scale flight test data," Bond said. Engineers also undertook a pioneering effort to define and develop the methodology for testing simulated icing shapes on rotors. "We constructed molds of the ice buildup on the blades, then produced castings or artificial ice shapes," Bond explained. Engineers now will attach these shapes to the leading edges of the scale model rotors for testing in a conventional (dry air) wind tunnel. "We'll compare these dry air wind tunnel results for artificial ice shapes with the Icing Research Tunnel test results," said Bond. This is the first time artificial ice shapes have been seriously suggested as part of the icing certification process for rotary-wing aircraft. Results of the testing will be made available to the U.S. helicopter industry for further recommendations. "We hope that the code predictions and artificial ice shapes ultimately can be accepted as an alternative to some of the icing flight testing now required by the Federal Aviation Administration to certify a helicopter for flight into forecasted icing," said Bond.

The cause for the RSLS abort was a faulty sensor that monitors fuel flow on main engine #2. No new launch date for Discovery has been set but managers indicate the delay will be at least 3 weeks. Work this weekend will center around securing the vehicle following the abort and making preparations to remove and replace the three main engines at the pad mid-next week. IN WORK TODAY: * Post scrub turn around and securing operations * Extend rotating service structure around orbiter * Install engine service platforms under vehicle * Orbiter mid-body umbilical mate and leak checks * ACTS battery discharge WORK SCHEDULED: * Off load onboard cryogenic reactants * Open aft engine compartment and install work platforms * Open payload bay doors * Reposition main engines and aerosurfaces * Troubleshoot faulty fuel flow sensor * Disconnect ordnance * Remove engine heatshields * Remove and replace all three main engines at the pad WORK COMPLETED: * Drain and boil-off cryogenic fuels in external tank ----------------------------------------------------------------- MISSION: STS-58 -- SPACELAB LIFE SCIENCES - 2 VEHICLE: Columbia/OV-102 ORBITAL ALTITUDE: 176 miles LOCATION: VAB high bay 3 INCLINATION: 39.00 degrees MISSION DURATION: 14 days CREW SIZE: 7 TARGET LAUNCH PERIOD: TBD LAUNCH TIME: TBD LAUNCH WINDOW: 2 hours, 30 minutes LANDING LOCATION: Edwards Air Force Base, Calif.

Audio Service: 202/358-3014 % STS-51 update; % Imaging principal investigator named. NASA managers have decided that Discovery's launch scrub was due to a problem with a sensor that monitors fuel flow through main engine #2. Engine cutoff occurred at 9:12 a.m. EDT. At this time it can not be determined when Discovery will be launched. However, there will be a delay of at least three weeks. * * * * * * * * * * * * * * * * NASA recently named Peter Smith of the University of Arizona, Tucson, as the Principal Investigator for the imaging system for the MESUR Pathfinder lander. MESUR (MARS Environmental Survey) Pathfinder is a small Discovery-class mission which NASA plans to launch to Mars in 1996. This launch will place a lander and rover on the surface of Mars in 1997. The MESUR pathfinder will use a small robotic rover to explore the region within about 50 meters of the landing site. The pathfinder will be capable of imaging in a variety of spectral bands to determine mineral content within view of the lander. The mission objective is to determine and identify rocks on the landing site which may be investigated further. The spectral mapping also will study weathering processes and products in the dust, soil and rocks of Mars. The MESUR pathfinder is scheduled to study Mar's surface for one month, with a goal of 1 year of extended mission. * * * * * * * * * * * * * * * * Here's the broadcast schedule for Public Affairs events on NASA TV.

PAST FLIGHTS FOR HAM RADIO: On November 28, 1983, STS-9 was launched carrying Mission Specialist Owen Garriott, Amateur Radio call sign W5LFL, and his ham radio into orbit. For 10 days the Space Shuttle Columbia streaked through the skies, and for the last 7 of those days, hams around the world were sent emotionally into orbit when they heard Dr. Garriott's voice break their squelches calling Earth-bound stations. But it was just the beginning. Amateur Radio had moved into its newest frontier, and it was there to stay.

The packet module contains a power supply and packet TNC. The power supply provides power for the TNC and the handheld transceiver. The TNC interconnects with a radio transceiver so that data to and from the computer is transmitted to and received from other amateur radio stations. Configuration C is capable of operating in either the voice or data mode in communications with amateur stations within LOS of the Orbiter. This configuration can be operated in the attended mode for voice communication and either the attended or automatic mode for data communications. The payload control weights are as follows: Configuration C 45 lb (20.41 kg) The American Radio Relay League, Newington Conn.

A press conference on Magellan's successful aerobraking was held at JPL on Tuesday, August 10 at 10:00 A.M. and broadcast on NASA-Select. The presenters were Doug Griffith, Ann Tavormina, Gerry Keating and Steve Saunders. 2. The Magellan aerobraking experiment demonstrated a significant new maneuver technology by achieving a major orbit change with minimal propellant and enabling new scientific observations near the poles of Venus. 3. Tuesday the Project marked the third anniversary of Magellan's arrival at Venus with an evening party attended by about 90 present and former team members, science investigators and friends.
