Because soldiers deserve the best
and because the modern battlefield is not limited to open lands,
the high performance and stealth Quasiturbine could help freedom!
Quasiturbine and the Military
Jet-A or Diesel Fuel
With a potential of 10 HP per pound or more in pneumatic or steam mode, the
Quasiturbine is an exceptional candidate for strategic military applications. For security and standardization
reasons, all military propulsions, air, marine and land, are moving toward Jet A fuel engine.
So far, no rotary engine can satisfactory run under Jet A.
The Quasiturbine Jet A fuel is of
strategic interest, since it is a
zero vibration engine,
which reduces the weight and the volume of conventional engine by a factor 4,
and the noise by a factor 20, low air flow almost
insensitive to air dust, its continuous combustion increases reliability, while the Quasiturbine produces less detectable heat! Possible zero EMF
(Electro-Magnetic Field) engine operation is also of great interest.
Furthermore, the Quasiturbine runs at a very low 200 to
3000 RPM (meaning a very long engine life time)
with an unusually high torque,
suppressing the use of gearboxes for many applications.
Due to steep pressure rise in the Quasiturbine,
the use of synchronized conventional injectors may not be necessary for some
The Quasiturbine can be submersible, since without crankcase oil pan nor electrical circuit.
Hybrid Quasiturbine-Fan (or Quasiturbine-Jet) offers potential for no
temperature limit in the jet nozzle! Considering the high power density, the low
cross section area and the exceptional intake characteristics of the
Quasiturbine, it is reasonable to expect to conceive airplane engines:
Enhance jet efficiency by recovering the waste gate exceeding compressed air
for other applications, like driving an APU (Auxiliary Power Unit).
In a propeller airplane, weight reduction
allows a larger payload or longer autonomy,
space saving allows to reduce the aerodynamic drag,
absence of vibration increases instruments reliability, photos quality and
the noise reduction increases the discretion level,
the high torque allows the use of multi-blades propeller
and the better intake characteristic of the Quasiturbine allows higher flight
The hybrid Quasiturbine-Fan (or Quasiturbine- Jet) engine
would be more powerful and efficient. In an helicopter, a large diameter
Quasiturbine could generate enough torque
to directly drive of the rotor blades without any gearbox, while making much less noise. The weight reduction of any equipment using a Quasiturbine makes it more
suitable for helicopter transportation.
Quasiturbine-Fan in which the Fan would be driven by a Quasiturbine, rather
than by a conventional power turbine.
- Quasiturbine-Fan Hybrid in which only the compressor would be driven by a Quasiturbine,
leaving all the reactor energy available to drive a still more powerful fan. The Quasiturbine air intake could come from the compressor. The empty center of the Quasiturbine would allow the shaft to go from the
power turbine to the fan.
- Quasiturbine-Jet reactor (no hot turbine). Still more revolutionary
would be a Jet Reactor without power turbine in the hot gas flow, where
the compressor would be driven by a Quasiturbine, leaving to the Jet all
its propulsive energy. The Quasiturbine air intake could come from the
compressor. In this last case, the suppression of the conventional power
turbine would permit to operate the engine at much higher temperature
without risking to melt the non-existent power turbine, and would permit
to substantially increase the speed and the efficiency. This
airplane engine would operate in the same mode as the rocket engine!
- For still a higher power density, the Quasiturbine could be fuelled
in pneumatic mode in hydrogen peroxide.
- For stealth
operation, a plastic made Quasiturbine is radar
undetected with a noise 20 times less than the conventional engine, and in pneumatic mode, the exhaust can be near ambient temperature, with
- With a potential of 10 HP per pound or more in pneumatic or steam
mode, the Quasiturbine is an exceptional candidate for burning
metal fuels (aluminum, magnesium or lithium). Aluminum is the most
energetic of these metal fuels, producing a reaction temperature of up
to 10,600 degrees Celsius. The heat from the combustion chamber would be
used to melt stored aluminum sheets at about 675 degrees C and to
vaporize water as well. High-pressure steam from this combustion process
expands out to drive a Quasiturbine. This would be an extremely high
power density aluminum-burning system.
- In rockets, the
Quasiturbine Pumps and Turbo-pumps would permit
a good control of fuel injection while reducing the equipment weight.
The Quasiturbine is an efficient direct hydrogen
combustion engine! These concepts would also permit to construct much less
complicated airplane engines and at a much lower cost than conventional
In a 30 tons tank, space saving
allows for more munitions and soldiers,
noise reduction and absence of vibration permit better observation and less
fatigue, low air flow almost insensitive to
and absence of gearbox increases reliability.
In a fast boat, the weight reduction allows for a better
over water surfing,
water stream jet integration in the center of the submersible Quasiturbine suppresses the
shaft and alignments,
and the vibration and noise reduction increases also the discretion level.
Outboard marine submersible Quasiturbine can also be of great interest.
In a pneumatic sub-marine,
everything is outside the habitable: the air tanks are underneath as emergency lest,
the Quasiturbine submersible jet propulsion is remote behind, and the Quasiturbine air exhaust is feed inside and
inhaled by the crew!
In a nuclear sub-marine, a steam Quasiturbine would produce the necessary
torque to directly drive the propeller shaft without delay in both directions
(reversing the flow), and would allow for a complete and quiet stop.
In a torpedo, a 1000
hp hydrogen peroxide fueled Quasiturbine would be more compact and lighter,
with a larger range, and producing an efficient multi-power level output (which
conventional turbines cannot allow).
In terrestrial multi-wheels
drive vehicles, independent pneumatic or hydraulic Quasiturbine can be all
connected to one central pressure distribution point such as to generate equal torque
independently from the individual RPM.
Torque modulation can further provide the vehicle direction control.
In portable units (power plants, pumps,
ventilators...), the weight reduction help transportation (and still more by integrating the
application in the center of the Quasiturbine),
the noise reduction and absence of vibration are particularly appreciated for
hand held units,
and pollution reduction makes a better humane operating condition.
In precision guided device,
the low harmonic Quasiturbine engine permits a precise RPM, power and acceleration control over a wider
EMF (Electro-Magnetic Field) engine operation, the Quasiturbine offers 5 modes: pneumatic, steam, continuous combustion, diesel and detonation.
With a potential of 10 HP per pound or more in pneumatic or steam mode, the
Quasiturbine is an exceptional candidate for the marine super-cavitating
vehicles burning metal fuels (aluminum, magnesium or lithium). This would be an
extremely high power density aluminum-burning "water ramjet" system.
SWATH Aircraft and Cargo Carriers...
A new type of engine can power this vessel
offering some significant advantages over current power plants.
We still want the
range and power advantages of nuclear power but we should replace the steam
turbines with Quasiturbines
for tremendous reductions in maintenance and
Nuclear power uses steam to drive turbines but the temperature of the steam is
relatively low and this causes fouling problems with the turbine.
Quasiturbine is more resistant to fouling, uses fewer parts, and can have
electrical generation hardware
integrated into the engine for reductions in size
and weight as well.
The Quasiturbine could also be physically coupled to
propellers or water jets.
While Quasiturbines can be steam driven, they can also
run from fuel combustion as well and can run on virtually any fuel, just like
What this means is that the same engine can be used to
power all of our large Navy vessels and submarines
- we only need to vary the
quantity of engines used to the application. This should streamline our support
and training needs considerably...
Engine Exhaust Heat Recovery:
By placing a hot Quasiturbine into or around an engine exhaust pipe, and
injecting pressurized hot water (steam keep in the liquid state for better heat
transfer), some heat can be recovered into mechanical energy. Stirling and short
steam circuit Quasiturbine could do similarly!
A 10 second vehicle Power Booster. Originally, hybrid was intended
for efficiency increase, not for performance increase. More and more
vehicles use 2 engines not for fuel savings, but to increase acceleration
performance: As a 10 seconds Power Booster, benefiting a government grant!
In this regards, the Quasiturbine QT600SC pneumatic with an onboard air
tank and compressor could eventually provide hundreds of additional HP for 10 seconds, and make
an unbeatable acceleration Quasiturbine Hybrid vehicle... the market seem
to ask for? Many others applications require high power bursts, like in
smooth landing parachuting (with fast line-winding in less than 10
Hydrogen - Nuclear Comment
A fleet is vulnerable because of the need of
tankers for refueling.
Only the aircraft carrier and the submarines are nuclear powered and therefore
autonomous for years. Give an aircraft carrier a plutonium-fed high temperature
nuclear reactors to produce hydrogen by thermo chemical reactions, then six reactors can produce 260 metric tons of hydrogen per day. This is approximately as
much energy as 900 tons of kerosene of fuel.
If hydrogen is not suited for military aircrafts, one can chemically
produce an heavier fuel (like an alcohol)
using hydrogen and CO2 captured from atmosphere. Hydrogen-fuelled frigate may have an hybrid propulsion: Fuel cells -
FC for base load power (low speed) and turbines for high power.
The Quasiturbine has both in one. It is an efficient steam engine and
an efficient direct hydrogen
combustion engine, which could make it play an important role on this
