8/13/93: NASA TESTS HELICOPTER MODEL IN ICING CONDITIONS
Drucella Andersen
Headquarters, Washington, D.C. August 13, 1993

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.

% 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.

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.

SAREX CONFIGURATION C - BACKGROUND
SAREX configuration C consists of the handheld transceiver, I/F module, PGSC,
spare battery set, window antenna, packet module, SAREX headset assembly,
personal recorder, and the required cable assemblies. 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:

Magellan Significant Events for Week Ending 8/13/93
1. 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.
Magellan Significant Events for Next Week
1. Circular orbit operations will officially begin on August 16th.
