Subj: NASA SR-71/YF-12 DATA (1/2)
|

Here is a four page fact sheet I recently picked up at the Dryden PA office.
|
||
It has a lot of interesting information about current and past Blackbird
|
||
activities at NASA Ames-Dryden...

|

|

SR-71
|
||
"The Blackbird"
|
||
|
||
Three SR-71 aircraft have been loaned to NASA by the U.S. Air Force as
|
||
testbeds for high speed, high altitude aeronautical research. The aircraft,
|
||
two SR-71A's and the only SR-71B pilot trainer aircraft in operation, are
|
||
based at NASA's Dryden Flight Research Facility, Edwards, Calif.
|
||
|
||
Developed for the U.S. Air Force as a reconnaissance aircraft more than
|
||
27 years ago, SR-71's are still the world's fastest and highest-flying
|
||
production aircraft.
|
||
|
||
The aircraft can fly more than 2200 mph (Mach 3+ or more than three times
|
||
the speed of sound) and at altitudes of over 85,000 feet. This operating
|
||
environment makes the aircraft excellent platforms to carry out research
|
||
and experiments in a variety of areas -- aerodynamics, propulsion,
|
||
structures, thermal protection materials, high-speed and high-temperature
|
||
instrumentation, and sonic boom characterization.
|
||
|
||
Data from the SR-71 high speed research program will be used to aid
|
||
designers of future supersonic/hypersonic aircraft and propulsion
|
||
systems. Beneficiaries of this data include a future high speed civil
|
||
transport and the National Aero-Space Plane (NASP) program.
|
||
|
||
|
||
Program Management
|
||
|
||
The SR-71 program at Dryden is part of NASA's overall high speed aeronautical
|
||
research program, and is expected to involve many NASA research centers, and
|
||
other government agencies.
|
||
|
||
Project manager at Dryden is David P. Lux
|
||
|
||
|
||
NASA Flight Crews
|
||
|
||
Each NASA crew consists of a pilot and a flight engineer.
|
||
|
||
Currently assigned as SR-71 project pilots at Dryden are Stephen D. Ishmael
|
||
and Roger E. Smith. Flight engineers are Robert E. Meyer and Marta Bohn-
|
||
Meyer. The Meyers are the first husband-wife team of aeronautical engineers
|
||
on flight status at Dryden.
|
||
|
||
Both pilot-engineer crews have trained for many hours in the SR-71 flight
|
||
simulator at Dryden to become thoroughly acquainted with aircraft systems
|
||
and operational procedures. The simulator is the same unit used by Air
|
||
Force personnel at Beale AFB, Calif., before the SR-71s were retired from
|
||
military service in 1990.
|
||
|
||
As military aircraft, SR-71's had a crew of two -- a pilot and a
|
||
reconnaissance systems officer.
|
||
|
||
|
||
Mach 3 at Dryden
|
||
|
||
Dryden has a decade of experience at sustained speeds above Mach 3.
|
||
Two YF-12 aircraft were flown at the facility between December 1969 and
|
||
November 1979 in a joint NASA/Air Force program to learn more about the
|
||
capabilities and limitations of high speed, high altitude flight.
|
||
|
||
The YF-12s were prototypes of a planned interceptor aircraft based on a
|
||
design that later evolved into the SR-71 reconnaissance aircraft.
|
||
|
||
Research information from the YF-12 program was used to validate analytical
|
||
theories and wind tunnel test techniques to help improve the design and
|
||
performance of future military and civil aircraft. The then-developing
|
||
American supersonic transport project would have benefited greatly from
|
||
YF-12 research data.
|
||
|
||
The aircraft were a YF-12A (serial 935) and a YF-12C (serial 937). They
|
||
logged a combined total of 242 flights during the program. A third aircraft,
|
||
a YF-12A (serial 936), was flown by Air Force crews early in the program.
|
||
It was lost because of an inflight fire in June 1971. The crew was not hurt.
|
||
|
||
The YF-12s were used for a wide range of experiments and research. Among the
|
||
areas investigated were aerodynamic loads, aerodynamic drag and skin
|
||
friction, heat transfer, thermal stresses, airframe and propulsion system
|
||
interactions, inlet control systems, high altitude turbulence, boundary layer
|
||
flow, landing gear dynamics, measurement of engine effluents for pollution
|
||
studies, noise measurements, and evaluation of a maintenance monitoring and
|
||
recording system.
|
||
|
||
On many YF-12 flights medical researchers obtained information on the
|
||
physiological and biomedical aspects of crews flying at sustained high
|
||
speeds.
|
||
|
||
From February 1972 until July 1973, the YF-12A was used for heat loads testing
|
||
in Dryden's High Temperature Loads Laboratory (now the Thermostructures
|
||
Research Facility). The data helped improve theoretical prediction methods
|
||
and computer models of that era dealing with structural loads, materials, and
|
||
heat distribution at up to 800 degrees (F), the same surface temperatures
|
||
reached during sustained speeds of Mach 3.
|
||
|
||
|
||
SR-71 Specifications & Performance
|
||
|
||
The SR-71 is a delta-wing aircraft designed and built by Lockheed. They
|
||
are powered by two Pratt and Whitney J-58 axial-flow turbojets with
|
||
afterburners, each producing 32,500 pounds of thrust.
|
||
|
||
Speed of the aircraft is announced at Mach 3.2 -- more than 2000 mph. They
|
||
have a range of more than 2000 miles and fly at altitudes of over 85,000 ft.
|
||
|
||
As research platforms, the aircraft can cruise at Mach 3 for more than one
|
||
hour. For thermal experiments, this can produce heat soak temperatures of
|
||
more than 600 degrees (F).
|
||
|
||
The aircraft are 107.4 feet long, have a wing span of 55.6 feet, and are
|
||
18.5 feet high (ground to top of rudders when parked).
|
||
|
||
Gross takeoff weight is about 140,000 pounds, including a fuel weight of
|
||
80,000 pounds.
|
||
|
||
The airframes are built almost entirely of titanium and titanium alloys to
|
||
withstand heat generated by sustained Mach 3 flight.
|
||
|
||
Aerodynamic control surfaces consist of all-moving vertical tail surfaces
|
||
above each engine nacelle, ailerons on the outer wings, and elevators on
|
||
the trailing edges between the engine exhaust nozzles.
|
||
|
||
The three SR-71's at Dryden have been assigned the following NASA tail numbers:
|
||
NASA 831 (B model), military serial 64-17956, manufactured in September 1965;
|
||
NASA 832 (A model), military serial 64-17971, manufactured in October 1966;
|
||
NASA 844 (A model), military serial 64-17980, manufactured in July 1967.
|
||
|
||
|
||
Development History
|
||
|
||
The SR-71 was designed by a team of Lockheed personnel led by Clarence
|
||
"Kelly" Johnson, at that time vice president of the company's Advanced
|
||
Development Projects. The Advanced Development Projects is commonly
|
||
referred to as the "Skunk Works".
|
||
|
||
The basic design of the SR-71 and YF-12 aircraft originated in secrecy in the
|
||
late 1950s with the aircraft designation of A-11. Its existence was publicly
|
||
announced by President Lyndon Johnson on Feb. 29, 1964, when he announced that
|
||
an A-11 had flown at sustained speeds of over 2000 mph during tests at
|
||
Edwards, Calif.
|
||
|
||
Development of the SR-71's from the A-11 design, as strategic reconnaissance
|
||
aircraft, began in February 1963. First flights of an SR-71 was on Dec. 22,
|
||
1964.
|
||
|
||
The YF-12's were experimental long-range interceptor versions of the same
|
||
airframe and were first displayed publicly at Edwards on Sept. 30, 1964.
