Quasiturbine 
Jet-A or Diesel fuel military engine

... even more that jet or Diesel...
With a potential of 10 HP per pounds or more in pneumatic or steam mode,
the Quasiturbine is an exceptional candidate for the marine supercavitating vehicles burning metal fuels (aluminum, magnesium or lithium) 
http://www.sciam.com/2001/0501issue/0501ashley.html 
Aluminum is the most energetic of these metal fuels, producing a reaction temperature of up to 10,600 degrees Celsius. 
One can accelerate the reaction by fluidizing the metal and using water vapor. 
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 (?) that turns a propeller screw.
 This would be an extremely high power density aluminum-burning "water ramjet" system.

The Quasiturbine theory analyses and optimizes 14 different engine parameters (see the book).

For security and standardization reason, all military propulsions are moving toward Jet A fuel engine.
So far, no rotary engine can properly 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 of 4, 
and the noise by a factor 20,
low air flow almost insensitive to air dusts,
continuous combustion increases reliability,
while the Quasiturbine produces less detectable heat !
Possible zero EMF (Electro-Magnetic Field) engine operation.

Furthermore, the Quasiturbine runs 
at a very low 200 to 3000 RPM (meaning a very long engine live 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 applications.
Submersible without crankcase nor electrical circuit.

Hybrid Quasiturbine-Fan (or Quasiturbine-Jet) 
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 an airplane engine:
1) Quasiturbine-Fan 
in which the Fan would be driven by a Quasiturbine,
rather that by a conventional power turbine. 
2) 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.
3) 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 efficiency. 
This airplane engine would operate in the same mode as the rocket engines!

For still a higher power density, 
the Quasiturbine could be fueled in pneumatic mode in hydrogen peroxide. 
Those concepts would also permit to construct much less complicated airplane engines 
and at a much lower cost than conventional turbines.

Various military applications

In a 30 tons tank, space saving allows for more munitions and soldiers,
noise reduction and absence of vibration permits better observations and less fatigue,
low air flow almost insensitive to air dusts,
and absence of gearbox increases reliability.

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 flight comfort,
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 altitude.
The hybrid Quasiturbine-Fan (or Quasiturbine- Jet) engine would be more powerful and efficient.
        See: http://quasiturbine.promci.qc.ca/QTULM.html 

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 make it more suitable for helicopter transportation.

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 habitacle: 
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 respirated by the crew!

In a nuclear sub-marine, a steam Quasiturbine
http://quasiturbine.promci.qc.ca/QTVapeur.html 
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 quite 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 turbine can not allows).

In terrestrial multi-wheels drive vehicles, independent pneumatic or hydraulic Quasiturbines 
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 plan, 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 range.

For zero EMF (Electro-Magnetic Field) engine operation, 
the Quasiturbine offers 5 modes: pneumatic, steam, 
continuous combustion, diesel and photo-detonation.

For stealth operation, a plastic made Quasiturbine is radar undetected 
with a noise 20 time less than the conventional engine, 
and in pneumatic mode,  the exhaust can be near ambient temperature, with zero EMF.

Under development, 
only RESEARCH APPLICATION PROTOTYPES
are custom made available at this time.
