aircraft at Dryden Flight Research Center, like these pictured
on the runway, have led to major advancements in the design and
capabilities of many civilian and military aircraft. Dryden's
Technology Transfer and Commercialization Office assists in the
transfer of this cutting-edge research and technology to the
U.S. aircraft industry. |
In March 1994, Dryden Flight Research Center became a full-fledged
field center. As a result of attaining center status, Dryden's
Technology Transfer and Commercialization (T2) office was officially
created in May 1995. The T2 office is now part of the "PACE"
group, which consists of Public Affairs, Commercialization, Education,
and History.
As NASA's primary installation for flight research over the
last fifty years, Dryden projects have led to major advancements
in the design and capabilities of many civilian and military
aircraft. The T2 staff work closely with a variety of clients,
from large aircraft companies to small business owners from the
start, to ensure that the technologies tested and developed at
the center can be directly integrated by its customers.
The T2 staff developed their own guidelines and work closely
with the researchers and engineers at the center to capture Dryden's
unique innovations. Aeronautics research at the center results
in technical papers, the essence of which are captured in NASA's
TechTracS database. The T2 staff also work in tandem with the
Research Engineering, Projects and Facilities directorates to
determine which innovations should be protected by patents.
In addition, the staff work closely with contracting managers'
technical representatives to determine what technologies have
been developed as a result of contracts, grants, and Small Business
Innovation Research (SBIR) contracts. This cooperation resulted
in many new patents and a faster transfer of new technologies
to U.S. industry. To facilitate new technology reporting, the
T2 staff encourage the companies to write articles for NASA
Tech Briefs, and follow up with press releases to help launch
the companies' new innovations.
Striving to meet the aggressive goals set forth by Administrator
Dan Goldin in NASA's Strategic Vision, the following projects
and partnerships provide an overview of Dryden's role in meeting
NASA's goals. This roadmap for the future is outlined and best
illustrated by the "Aeronautics and Space Transportation
Technology: Three Pillars for Success."
Pillar One: Global Civil Aviation
To preserve the nation's economic health and the welfare of
the traveling public, the first pillar focuses on safety, environmental
compatibility, and affordable air travel. Dryden's first goal
is to reduce the aircraft accident rate by a factor of five within
ten years and by a factor of ten within twenty years. To meet
the challenge, current innovations and programs include the patented
Propulsion-Controlled Aircraft, the Structural Health Monitoring
System on Systems Research Aircraft for X-33, and the Lidar Clear
Air Turbulence Measurement, developed under an SBIR contract
by Coherent Technologies.
The innovative work of reducing emissions of future aircraft
by a factor of three within ten years, and five within twenty
years, is ongoing. In addition, a new family of remotely-piloted
vehicles (RPVs) that fly slower, higher, and longer are being
developed. These long-duration, high-altitude RPVs could be used
in upper-atmosphere science missions to help collect, identify,
and monitor environmental data to assess global change. They
could also carry telecommunications equipment to high altitudes,
serving much like satellites for a fraction of the cost of putting
traditional satellites in space.
The Environmental Research Aircraft and Sensor Technology
(ERAST) partnership has yielded significant technological advancements
to meet the second goal of the first pillar--environmental compatibility.
Besides Dryden, three other NASA research centers (Ames, Langley,
and Lewis), along with The Association for Unmanned Vehicle Systems
International, American Technology Initiatives Inc., Thermo Mechanical
Systems Inc., and several universities are included as partners.
The major industry partners are listed below in parentheses,
after the names of the unpiloted aircraft, which are products
of the ERAST partnership.
- Pathfinder (AeroVironment Inc.) is a proof-of-concept vehicle
for two more prototype solar-powered aircraft that have the ability
to study the upper atmosphere without disturbing it. Remote monitoring
of storm developments, forests, and crop damage are also benefits.
- Apex (Advanced Soaring Concepts, Inc.) is used to validate
high-altitude testbed aircraft design methodologies by measuring
airfoil characteristics at low Reynolds numbers and high subsonic
Mach numbers in a low-turbulence environment.
- Perseus B (Aurora Flight Sciences Corp.) involves test engine
concepts, lightweight structures, science payload integration,
and fault tolerant flight control systems.
- Altus (General Atomics Aeronautical System Inc.) verifies
technologies that lead to a long-duration, high-altitude vehicle
that could carry science payloads.
- Demonstrator-2 (Scaled Composites Inc.) centers on over-the-horizon
communication capabilities, lightweight structures, science payload
integration, engine development, and flight control systems.
The second goal is to reduce the perceived noise levels of
future aircraft by a factor of two from today's subsonic aircraft
within ten years, and by a factor of four within twenty years.
Dryden is currently flying the SR-71 aircraft, on loan from the
U.S. Air Force, to study sonic boom propagation. Data from the
SR-71 high speed research program will be used to aid designers
of future supersonic/hypersonic aircraft and propulsion systems,
including a high speed civil transport.
The final goal is affordable air travel. While maintaining
safety, Dryden strives to triple the aviation system throughout,
in all weather conditions within ten years. Reducing the cost
of air travel by twenty-five percent within ten years and by
fifty percent within twenty years, is being accomplished by Orbital
Sciences' patented Adaptive Performance Optimization, Electro
Hydrostatic Actuator, the Fiber Optic Position Measurement Network,
and the Smart Actuator, which reduces wire weight by sixty percent
and detects its own internal failures; thereby reducing maintenance
costs.
| Demonstrator-2, one of
the projects within the ERAST program, was built by Scaled Composites
Inc., and is testing technologies that could result in long-duration
(12 to 72 hours), high-altitude vehicles capable of carrying
science payloads. Lightweight structures, science payload integration,
engine development and flight-control systems are key technology
development areas for this project. |
Pillar Two: Revolutionary Technology Leaps
NASA's objective outlined in the second pillar is to explore
high-risk technology areas that can revolutionize air travel
and create new markets for U.S. industry. The technology challenges
for NASA include: eliminating the barriers to affordable supersonic
travel, expanding general aviation, and accelerating the application
of technology advances.
The first technology goal is to reduce the travel time to
the Far East and Europe by fifty percent within twenty years,
and to do so at today's subsonic ticket prices. To break the
barriers to high speed travel, Dryden has imitated several programs
including the TU-1 44LL Initiative.
The Russian TU-144LL supersonic transport is being used as
a flight research test vehicle to conduct experiments which will
enhance the development of advanced technology necessary to build
the next generation high speed civil transport. The purpose of
the program is threefold: develop and transfer supersonic airliner
technology directly to U.S. aircraft industry under NASA sponsorship;
establish a working relationship between U.S. and former Russian
aircraft manufacturers at programmatic and technical levels;
and acquire flight research data and existing operational experience
to narrow the margin of European supersonic transport experience
gained from the Concorde.
Dryden is also dedicated to providing next-generation design
tools and experimental aircraft to increase design confidence
and cut the development cycle in half. This goal is being accomplished
through several programs including: the Hyper-X program, which
will demonstrate hypersonic propulsion technologies; the X-36
Tailless Fighter Agility Research Aircraft, a remotely-piloted
jet designed to fly without traditional tail surfaces aimed at
improving the maneuverability and survivability of future fighter
aircraft; and the Linear Aerospike SR-71 Experiment (LASRE),
designed to gather data on the aerospike's exhaust plume as it
travels through the transonic region of flight (just below to
just above Mach 1).
| NASA, industry, and universities
are working together as Environmental Research Aircraft and Sensor
Technology (ERAST) partners to develop a new family of remotely-piloted
vehicles that will fly slower, higher, and longer than ever before. |
Pillar Three: Access to Space
Finally, low-cost space access is essential to unleashing
the commercial potential of space and greatly expanding space
research and integration. NASA's primary space transportation
technology role is to develop and demonstrate pre-competitive,
next-generation technology that will enable the commercial launch
industry to develop full-scale, highly competitive, and reliable
space launchers.
Dryden is pushing ahead with two programs with objectives
to meet the goal of this last pillar. First, in partnership with
Lockheed-Martin in the X-33 program, Dryden aims to reduce the
payload cost to low-Earth orbit by an order of magnitude, from
$10,000 per pound within ten years. Second, in partnership with
Kelly Aerospace, the Eclipse program goal is to reduce the payload
cost to low-Earth orbit by an additional order of magnitude,
from thousands to hundreds of dollars per pound, by the year
2020.
The flight research programs initiated at Dryden help move
the U.S. aircraft industry closer to achieving its goals. And
everyday the efforts of the Technology Transfer and Commercialization
office take Dryden Flight Research Center one step closer to
realizing its vision statement: "The world leader in flight
research for discovery, technology development, and technology
transfer for U.S. aeronautics and space preeminence."
