Thesis: The F-117A, an expensive aircraft, is constructed from
|
|
high-tech material, which results in effective, surprising attacks and a
|
|
foundation for improvement on future air technology.
|
|
|
|
I. Imagine being a foreign soldier guarding an important army depot.
|
|
Five minutes pass quietly and quickly, and then in just 30
|
|
seconds you are blown away with your army depot. How could this
|
|
have happened? Why didn't your air defense systems go off?
|
|
Well, maybe it could've been the USAF F-117A Stealth Fighter.
|
|
The F-117A, an expensive aircraft, is constructed from
|
|
high-tech material, which results in effective, surprising
|
|
attacks and a foundation for improvement on future air technology.
|
|
|
|
II. F-117A developed and unveiled by US Air Force.
|
|
A. After 10 years, the USAF has taken its covers off its top
|
|
secret stealth fighter.
|
|
B. Built by Lockheed Aeronautical Systems Co., the F-117A is
|
|
described as a fighter craft.
|
|
C. However, since it is by no means a dog fighter, the aircraft
|
|
is primarily designed for surprise, prescision attacks
|
|
on ground targets.
|
|
|
|
III. Many new and high-tech equipment is used to create the unique
|
|
aircraft.
|
|
A. The dimensions for the single seater jet are 43 feet 4
|
|
inches for the wingspan, 65 feet 11 inches for its
|
|
length, and 12 feet 5 inches for height.
|
|
B. Its maximum wright is 52,500 lbs.
|
|
C. Two General Electric F-404 turbo fan engines makeup the
|
|
plane's powerplant.
|
|
1. They are covered with a radar-absorptive composite
|
|
grid that blends into the lines of the wing.
|
|
2. Exhaust of the engines, which produce an estimated
|
|
12,000 lbs of thrust (about half of the F-15E
|
|
powerplant), is deflected upward throught the
|
|
grid, which creates a non-afterburning effect.
|
|
D. The F-117A's control feature is a digital,
|
|
quadruple redundant fly-by-wire.
|
|
1. No different from other modern fighters.
|
|
2. An onboard computer assists in flying (fly-by-wire)
|
|
3. 4 channels are programmed to perform the same
|
|
functions.
|
|
a. If 2 channels fail, the plane is still
|
|
operable.
|
|
b. It gives freedom to airframe designers to
|
|
build higher performance levels.
|
|
c. Secondly, it results in very precise control.
|
|
E. It travels at high subsonic speed.
|
|
F. The F-117A has unlimited range of operation due to air
|
|
refueling techniques.
|
|
G. The aircraft can support the most diverse weapons.
|
|
1. The bomb doors measure about 17 feet long, most likely
|
|
carrying two 2000-lb lasr-guided penetration
|
|
bombs or AGM-65 Maverick guided missles, since
|
|
they are most commonly used for ground attacks.
|
|
2. However, they can carry HARM missles, which are
|
|
enemy-radar tracking missle, or even PENGUINs,
|
|
which are designed to skim the water for attack
|
|
on missle boat.
|
|
H. The one of the most significant parts in the plane is its
|
|
materials.
|
|
1. The structure is primarily aluminum.
|
|
2. However, a skin of flat, rough Radar Absorbing
|
|
Material (RAM) tiles, made of either a ferrite
|
|
or polymer material, surrounds the aluminum.
|
|
3. The dual vertical tail fins of all the stealth
|
|
fighters are being replaced with a thermoplastic
|
|
graphite material, which provides greater
|
|
reliability and longer life.
|
|
I. The other significant part is its faceted design.
|
|
1. Any radar signals not absorbed by the craft's paint
|
|
and skin would bounce back a signal that would
|
|
appear to be unrecognizable "noise".
|
|
2. The leading edge of the wings, like every angle of
|
|
the aircraft, tapers to a knife edge instead of
|
|
the rounded form usually thought necessary to
|
|
provide lift to an airplane.
|
|
3. A sawtooth design on the borders of the cockpit
|
|
windows also is thought to scramble radar
|
|
signals.
|
|
4. As a result of such design, the fighter is said to
|
|
have a radar cross section (RCS) of about 0.01
|
|
sq meters, which is about the size of a bird.
|
|
--However compare this to the 40 sq meter RCS pf
|
|
a B-52 bomber.
|
|
J. Each plane costs $42.6 million dollars, while the whole
|
|
program spending of $6.56 billion.
|
|
|
|
IV. Recent missions prove the F-117A to be effective.
|
|
A. Due to its stealth qualities, it doesn't need to hug the
|
|
ground to avoid radar dection.
|
|
B. It can approach as high as 25,000 ft then drop down to
|
|
deliver its payload.
|
|
C. On the night of Dec. 19, 1989, six stealth fighters flew
|
|
nonstop to Panama and back to US as part of the Panama
|
|
invasion.
|
|
1. Four were committed to combat, which includes
|
|
supporting an air drop of Army rangers.
|
|
2. Also they delivered a payload of 2000-lb bombs on
|
|
Rio Hato, where an elite group of Noriega's
|
|
forces were based.
|
|
D. Also, F-117As destroyed an estimated 95% of every primary
|
|
Desert Storm target in the Iraqi capital of Baghdad,
|
|
according to American military planners.
|
|
1. They penetrated Baghdad's airspace despite the city's
|
|
heavy defenses.
|
|
2. The planes also made accurate hits.
|
|
a. One target was an Iraqi air force
|
|
headquarters.
|
|
1. The multistory building was hit by a
|
|
bomb dropped through the top of
|
|
the structure.
|
|
2. The impact point was almost dead
|
|
center in the roof.
|
|
b. The concrete Iraqi air defense HQ was also
|
|
damaged.
|
|
1. The bomb was guided through one of three
|
|
air shafts in the roof.
|
|
2. It entered the shaft, followed by an
|
|
explosion that blew out the
|
|
building's forward air lock
|
|
door.
|
|
c. Brig. Gen. Glossen, USAF target planner,
|
|
revealed that the F-117As successfully
|
|
attacked the aircraft shelters at the
|
|
Kirkuk, H2, and Talill airfields.
|
|
|
|
V. Professor Drela believes that the shape is unnecessary in future
|
|
stealth fighters.
|
|
A. The shape resulted due to the limited ability of engineers
|
|
back in the 1970s to model radar cross section.
|
|
B. This severe shape takes its toll on aerodynamics and
|
|
maneuverability.
|
|
C. With better design tools and greater computers, engineers
|
|
can now tackle the difficulty of predicting radar
|
|
signatures of curved surfaces.
|
|
-- Thus, the B-2 stealth bomber has taken on a more
|
|
rounded shape.
|
|
|
|
VI. High-Tech aircrafts are proven to have advantages over other
|
|
countries, so the USA is trying to have the largest and most
|
|
update weapons around.
|
|
|
|
A. With the creation of the F-117A and its accomplishments, the
|
|
USAF can now try and create bigger and more stealther
|
|
weapons ever before.
|
|
B. The F-117A may be the "weapon" that will separate the US
|
|
from the other countries.
|
|
|
|
Conclusion: VII. The US has now proven to be the leader of military
|
|
power. America is now stockpiling for later use of their
|
|
weapons. Also with their variety and update weapons, America
|
|
CAN be the leader for a very long time.
