NEW 'PULSER' SIGHTINGS
|
|
|
|
"Donuts-on-a-rope" contrails produced by an unknown high-speed,
|
|
high-altitude aircraft have been reported throughout the U.S.
|
|
and Europe, suggesting the classified "pulser" is no longer
|
|
confined to a test range (AW&ST May 11, p.62).In late January,
|
|
a similar contrail--described as a "coiled spring"--was seen
|
|
over Scotland behind a very fast aircraft flying east to west.
|
|
The distinctive contrails have been spotted during daylight hours
|
|
over Portland, Ore.; Washington Dulles International Airport, Va.;
|
|
Denver, Colo.; and Edwards AFB, Calif.Observers said the main
|
|
plume appeared to be connected directly to the aircraft, which
|
|
was so high its shape could not be determined.Typical jet
|
|
contrails become visible at some distance behind an aircraft as
|
|
moisture in the exhaust condenses. The pulser's rings or "donuts"
|
|
appeared to grow out of and encircle the plume a few seconds later.
|
|
Propulsion experts have suggested the "pulser" may be powered by
|
|
a ducted rocket, or a hybrid of a pulse detonation engine.

|
COMBINED CYCLE POWERPLANT
|
|
|
|
"DOUGHNUTS ON A ROPE" contrails produced by unknown high-speed,
|
|
high-altitude aircraft may be the result of a Pratt & Whitney
|
|
powerplant program aimed at developing what the company calls
|
|
an "impulse motor". The engine is believed to be a combined
|
|
cycle powerplant that integrates conventional gas turbine and
|
|
rocket technologies. Such a powerplant would be capable of
|
|
operating from a ground takeoff up to speeds approaching Mach 6.
|
|
[ and of course that is the magic "Aurora" number! :-> ]
|
|
|
|
The unusual contrail could be the result of running the powerplant
|
|
off its narrow design point, according to U.S. propulsion experts.
|
|
Officials have suggested that in the past, impulse engines have
|
|
been located at Edwards AFB, Calif., and at government facilities
|
|
at White Sands, N.M.
