One could wish that this was further evidence that Jim Bowery actually
has a sense of humour, but it isn't. He actually seriously believes
something this silly, apparently. Then he wonders when people
question his credibility, which he himself demolishes with
lunatic-fringe statements like this.
Simple question, Jim. If you are as important as you think you are
and NASA is peopled by the arch-demons you believe it is, why are you
still alive?

Yo buddy, in case you haven't heard, the last President
appointed a guy named Dan Goldin to head NASA, and since
his first day on the job in early 1992 he has been on
a big-time campaign to reform NASA. Let's talk about Goldin's reforms
in technology development areas. Goldin has been very critical of
technology development activities that have gone on year after
year with the fine research continuing but nobody *using* the
technology that's been developed. In this era of TQM (another
Goldin reform at NASA), Goldin has the technology development
crowd defining their customers - the idea is if the development
community cannot find a user for the technology they are
developing, bye-bye funding.

First off, apparently it's obvious to you which technologies are
"of great economic and social import" and should therefore
receive generous funding, and the other technologies which the
government chooses to fund that are "incorrect technical
directions." It seems to me one person's "great economic and
social import" could very well be another person's "incorrect
technical direction." I have personally reviewed some of the
unsolicited Small Business Innovation Research proposals sent to
NASA Lewis. I assume the author of each proposal feels his/her
idea is "of great economic and social import." I have recommended
rejecting some of the proposals, as the author either didn't do
his/her homework (i.e. the author did not look into what papers
have been already published on the topic), or they want funding
to study the proverbial perpetual motion machine.
As I mentioned earlier, Goldin is trying to re-direct the
technology development program. I personally think the
development activities on the aeronautics side of NASA have been
closely coordinated with the "users" - the US aviation industry
(comments from Mary @ Dryden are welcome), while the aerospace
development activities would do well to emulate the aeronautics
activities.
Have you ever read a publication like NASA Lewis 1992 Research
and Technology report (NASA Technical Memorandum 105924)? The
document summarizes the progress made during the year in various
technology development programs. Let's look at a few of them
which the government did fund, and let the readers decide if
we're picking "incorrect technical directions" instead of the
optimum development activities of "great economic and social
import." ...

Broad-Speed-Range Engines Proposed for Advanced High-Speed Tilt
Rotor Transports
Advanced tilt rotor transports may help alleviate airport
overcrowding without building new larger airfields. This aircraft
takes off and lands vertically with the rotors in a horizontal
position.
Takeoff and landing require a high-subsonic rotor tip velocity.
However, for quiet, efficient cruise operation the sum of the
rotor tip speed due to rotation and that due to forward velocity
must remain subsonic. The rotor, now acting as a propeller, must
rotate as much as 50% slower than during takeoff and landing.
Reducing the engine rotational speed to do this would result in
18% larger engines with 20% worse specific fuel consumption.
The solution is to develop new engine systems that can run
efficiently at both high and low speeds while operating at full
power - the broad-speed-range engine. As part of the contracted
efforts Allison Gas Turbine Division of GM and General Electric
studied several concepts. Three proved most attractive - reduced-
stage-loading power turbine adds stages to the turbine, the
counterrotating turbine, and the two-speed shiftable
transmission.
------------------------------------------------
Ceramic Turbine Stage Components Tested to 2500F
In order to exploit the high-temperature performance potential of
the gas turbine engine without using strategic materials or
exotic hot-section cooling techniques, NASA Lewis is working to
develop a ceramic component technology base. As part of the US
DOE Automotive Gas Turbine Program, the Advanced Turbine
Technology Applications Project is developing structural ceramic
hot-flow-path component technology for advanced small gas turbine
engines. These engines, designed to operate at temperatures to
2500F, have the potential for significantly less fuel consumption
than either metal turbine engines or conventional piston engines.
In addition, the turbine engines operate with reduced emission
levels that meet the current and proposed Federal standards.
Technology development contracts are in place with the Allison
Gas Turbine Division of GM and with the Garrett Auxiliary Power
Division of the Allied-Signal Aerospace Company.
----------------------------------------------------
Shed-Ice Impact Energy Measurement System Developed
The NASA Lewis aircraft icing group has developed a shed-ice
impact energy measurement system to characterize the impact force
or energy associated with ice particles shed from a rotating
system, such as a propeller or a helicopter main rotor. This
system was developed in response to a stated industry need for a
data base of impact forces and energies associated with shed-ice
particles to use in predicting potential airframe damage from
shed-ice particles. The system was successfully used in a model
rotor icing test in the NASA Lewis Icing Research Tunnel where
over 300 shed-ice impacts were recorded. The proof-of-concept of
the system was developed through a grant with the University of
Toledo.
------------------------------------------------------
Novel Face Gears Proved Feasible for Advanced Rotorcraft
Transmissions
The Advanced Rotorcraft Transmission Program is an Army-funded,
joint NASA/Army program to develop and demonstrate lightweight,
quiet, and durable drivetrains for next generation rotorcraft.
One contract team participant (McDonnell Douglas Helicopter
Company / Lucas Western Incorporated) developed a novel design
with a projected weight saving of 40% over a conventional design.
The new design consisted of face gears in a split-torque
arrangement never before used in rotorcraft transmissions.
Prototype face gears were tested in the NASA Lewis Gear and
Transmission Laboratory to demonstrate their feasibility in a
high-speed, high-load application.
---------------------------------------------------------
Mixer-Ejector Nozzle Tested for Aerodynamic Performance and Noise
Suppression.
The High Speed Civil Transport is a proposed supersonic transport
capable of carrying 300 passengers on transoceanic routes. Such
an aircraft must meet Federal noise regulations to be acceptable
to communities surrounding airports. Although the only operating
supersonic transport, the Concord, has been granted an exemption
from FAA noise standards, such waivers probably will not be given
to future supersonic transports. However, the high thrust needed
to boost these aircraft to supersonic speeds implies high jet
velocities and thus high noise levels. As part of the High Speed
Research Program, NASA and Pratt & Whitney are working together
to develop technology that will reduce the noise produced by
these engines while maintaining thrust levels.
------------------------------------------------------------
F-18 Inlet Flow Calculated at Combination of High Angle of Attack
and Moderate Side Slip.
NASA Lewis is currently engaged in a research effort as a team
member of the High Alpha Technology Program within NASA. This
program utilizes a specially equipped F-18, the high alpha
research vehicle, in an ambitious effort to improve the
maneuverability of high-performance military aircraft at low-
subsonic-speed, high-angle-of-attack conditions. The overall
objective of the Lewis effort is to develop inlet technology that
will ensure efficient airflow delivery to the engine during these
maneuvers. The numerical results will be used to support wind
tunnel tests at NASA Lewis and flight tests at NASA Dryden.

Laser Light Scattering Provides a Clear Vision of the Future.
A compact fiber optic probe developed for on-orbit science
experiments has been used to detect the onset of cataracts, a
capability that could eliminate physicians' guesswork and result
in new drugs to dissolve cataracts before surgery is necessary.
This probe is a spinoff of an advanced technology development
program in laser light scattering at NASA Lewis that has reduced
a small roomfull of electronics, detectors, lasers, and
associated optics to the size of a briefcase. This progress will
permit experiments in microgravity that can quantitatively answer
basic science questions about nucleation, critical phenomena,
aggregation, diffusion, etc., in an environment unfettered by
convection and sedimentation effects. Meanwhile, ground-based
spinoffs of this work will be impacting our lives in the near
future.

Structural Health-Monitoring System Developed for Composite
Aerospace Structures.
To reduce operating expenses, airlines are now using the existing
fleets of commercial aircraft well beyond their originally
anticipated service lives. The repair and maintenance of these
"aging aircraft" has become a critical safety issue, both to the
airlines and the FAA. A measurement system is therefore required
to continuously monitor the damage and structural degradation of
aging airframes that result from the repeated takeoff/landing and
pressurization/depressurization cycles that aircraft routinely
experience.
An innovative effort has been conducted to develop such a
monitoring system. The approach is to monitor the vibration of an
in-service structural component and then use a computer-based
pattern recognition algorithm to estimate, from these
measurements, the extent of damage in the structure. Structural
Integrity Associates, Inc., of San Jose, California, recently
demonstrated the feasibility of this approach as part of a Small
Business Innovation Research contract with NASA Lewis. The
results showed that a pattern recognition algorithm could be
"trained," by using laboratory test data, to recognize certain
characteristic changes in structural frequency response and to
infer from those changes the amount of ply delamination, matrix
cracking, or both in a composite structural component.
-------------------------------------------------------------
Foil Bearing Computer Code Developed.
Foil bearings are considered to be a potential alternative to
rolling-element bearings for turbopump applications because of
their inherent operating characteristics including virtually
infinite life, tolerance of debris and misalignment, reduced
thermal distortion, and the potential for enhanced dynamic
performance. Therefore, NASA Lewis is sponsoring a grant effort
to develop predictive analysis tools for the design and
performance evaluation of foil bearings.
Funded by the grant, Penn State University developed Foil
LUBrication, a finite-element-based code capable of predicting
the steady-state performance of foil bearings. There are plans to
enhance the code's capabilities through a follow-on effort. A
three-year program to completely develop the bearing code was
jointly defined by Penn State and Akron University. Akron will
develop a thermal model and a Navier-Stokes-based fluid model,
while Penn State will develop an analytical perturbation
technique for predicting the dynamic performance of foil
bearings.
------------------------------------------------------------
Titanium Precursors Chemically Vapor Deposited
Titanium and its alloys are critical for numerous aerospace
applications because of their high specific strength at elevated
temperatures, hardness, and resistance to wear and corrosion. Of
all metal and metal alloy deposition processes, chemical vapor
deposition (CVD) is perhaps the most suitable for forming the
reliable and reproducible multilevel structures required.
The current program focuses on Low Temperature CVD of titanium
and all its alloys by using a series of novel precursors through
thermal and plasma-assisted CVD. The precursors are being
synthesized at NASA Lewis with assistance from Cleveland State
University. The State University of New York at Albany is
depositing and characterizing the films. Further characterization
using surface and analytical instrumentation and electrical and
mechanical testing of CVD-deposited films is being conducted at
IBM and Motorola. Initial results show that high-quality
conducting titanium films with low carbon and oxygen content can
be deposited from titanium sandwich compounds onto 5-in diameter
silicon wafers. The deposition process involves plasma-assisted
CVD below 400C. Current work involves the development of
alternative precursors for low temperature CVD by using only a
thermal process.
-------------------------------------------------------------
Robust, Lightweight Stirling Engine Heater Head Fabricated
A technological milestone has been achieved during 1992 by the
successful fabrication of the Starfish heater for the 12.5 kWe
component test power converter (CTPC). The objective of the work
was to develop a lightweight, strong, high-performance heat
exchanger that would be more reliable than conventional heat
exchangers. The resulting design was a sodium-vapor-to-helium-gas
heat exchanger, called Starfish, that is machined from a solid
block of Inconel 718 superalloy material by electrochemical
methods, thereby eliminating all braze joints. The name Starfish
reflects the radial configuration of the heat exchanger fins.
This work is part of an overall effort to develop all the
technology necessary to design, fabricate, and test a high-
efficiency, low-specific-mass, 12 kWe Stirling space power
converter capable (SSPC) of long-life (60,000 hr) operation. The
CTPC and SSPC will operate with the Starfish heater at 1050K and
the converter cold end at 525K. The work is being performed under
NASA contract by Mechanical Technology Inc. of Latham, New York.
-------------------------------------------------------------
Lightweight Nickel/Hydrogen Cells Developed
As part of the nickel/hydrogen (NiH2) cell technology program at
NASA Lewis an advanced NiH2 cell design was developed. A goal was
to improve the specific energy of the state-of-the-art NiH2 cell
from 50 to 100 W-hr/kg. One of the components necessary to
accomplish this goal is a lighter weight nickel electrode. The
use of light-weight nickel plaque in place of heavy sintered
nickel plaque will lessen the weight of the nickel electrode.
These plaques (fiber and felt) are fabricated into nickel
electrodes by electrochemically impregnating them with the nickel
hydroxide active material. After preliminary experiments the
Fibrex fiber plaque from National Standard, Niles, Michigan, was
selected as one of the most promising support candidates for the
active material.
The lightweight NiH2 cell program is a combined effort. A
contract with Hughes Aircraft Company to improve the capacity and
initial performance of the Fibrex nickel electrode is currently
under way. A grant with the Space Power Institute (Auburn
University) to develop high-performance electrochemical systems
utilizing composite electrode structures is in progress. These
electrodes will be tested in a NiH2 cell at Hughes and NASA
Lewis.

If you've read through all these examples, you'll hopefully
conclude that NASA isn't out in left developing technologies
nobody gives a hoot about (let alone hiring hit men to get
rid of technology developers we don't like).

Is "war" defined in the US constitution? One certainly might suggest that the
theft of large sums of money from the national treasury constituted an act of war.
(Or to put it another way, can only countries declare war on other countries?)

No. Only the method by which the country passes a declaration
of war.

Does that mean we should send tanks to texas to collect on those
failed S&Ls? if that wasn't a theft of money from the national
treasury, i don't know what was.
>(Or to put it another way, can only countries declare war on other countries?)
no, but if you aren't a country, does anyone care?
I seem to recall some canadian environmentalists declared war on the US.
something about USAF training missions in canada. even threatened to
shoot at them with his .22 rifle.
lots of little countries threaten stuff, no-one listens to them either.
I think the libyans threatened war a couple of times over the gulf
of sidra. no-one cared.
