A quasiturbine is a type of rotary engine that operates using a unique and innovative mechanism. Unlike traditional engines, which rely on reciprocating pistons or rotating disks, the quasiturbine uses a rotating annular chamber to generate power. This makes it a potentially more efficient and compact alternative to traditional engines, with applications in a wide range of fields including automotive, aerospace, and marine industries.
One of the main advantages of the quasiturbine is its ability to operate smoothly at a wide range of speeds. This is due to its unique mechanism, which uses a series of vanes that move within an annular chamber to create rotational motion. As the vanes move around the chamber, they compress and expand gases, which drives the rotation of the engine. This continuous motion is more efficient and produces less vibration compared to the stop-start motion of traditional engines.
In addition to its smooth operation, the quasiturbine also has a high power-to-weight ratio, making it suitable for use in lightweight vehicles such as aircraft and drones. It is also highly efficient, with some designs able to reach thermal efficiencies of up to 50%.
Another potential advantage of the quasiturbine is its versatility. It can be designed to run on a wide range of fuels, including gasoline, diesel, and even hydrogen. It can also be used to power pumps and generators, making it a useful tool in a variety of applications.
Despite its many potential benefits, the quasiturbine is not without its challenges. One major hurdle is the high cost of production, which has limited its adoption in the automotive industry. Additionally, the design of the quasiturbine is relatively complex, which can make it more difficult to manufacture and maintain compared to traditional engines.
Overall, the quasiturbine is a promising alternative to traditional engines that offers a number of potential benefits. Its smooth operation, high efficiency, and versatility make it a potentially valuable tool in a variety of industries. However, further development and research are needed to overcome challenges such as high production costs and complex design in order to fully realize its potential.
What does Quasiturbine mean?
. However, to produce the power necessary for the propulsion of a vehicle with reasonable Quasiturbine size QT75SC , a differential of pressure from 50 to 100 psi is enough. The main frame is built. Souvent, l'optimum est d'utiliser les thermies basses températures comme préchauffe d'un cycle à plus haute température, au quel cas l'efficacité différentielle du carburant utiliser pour la haute température est bonifiée. QUASITURBINE HYDRAULIC PUMP Double reversible circuits and self-priming demonstration QUASITURBINE INTERNAL COMBUSTION produit not offered Test bench made by a group of volunteers at from an internal combustion engine block loaned par Quasiturbine. Only by all of us working as aware crewmembers of spaceship Earth - for the benefit of every crewmember, instead of selfishly for ourselves can we ever hope to escape the slavery that we are in right now. It goes without saying that acknowledging its existence may fall into the realm of a social obligation.
The motionless rim design makes thevehicleunique where the tire travels around the rim by utilizing maglev train like magnets that controls all propulsion and braking functions. Because the exhaust and the intake chambers stay at the same pressure during the transfer, that pressure would not be a constraining back pressure to the first stage. The cooling effect must not be under-estimated. At the very least, it will have to use extremely clean fuel because of junk acumulating on moving parts. This high performance cycle is specially simple to built, non polluant, and appear well suitable for mobile units. Nothing prevents from juxtaposing 3 Quasiturbines of different dimensions to do still better! A Thermo-Pneumatic Quasiturbine Locomotive with addendum on subway operation A demonstration liquid nitrogen motorcycle Concours Force Avenir Why is the Quasiturbine revolutionizing the use of steam and solar energy? This heterogeneous mixture is then compressed, which causes the temperature to rise until self-ignition takes place.
Assuming that an ambient temperature heat source is always available for free, a gallon of liquid nitrogen contains only 10 to 15 times less mechanical energy than a gallon of gasoline used at 10% efficiency in today's vehicles, and it creates zero pollution! The two-seater ZIV or Zero Impact Vehicleconcept has been designed to offer a greener life style for busy urban environment by using recycled or reclaimed materials only. Large utility plants convert energy more efficiently than small distributed units and should be favored when possible, but on the long term, the Quasiturbine detonation engine is one of the very few means to match utility efficiency the distributed way, while being as chemically clean as possible. In fact, in all expansion thermal machine the Quasiturbine being one of the most efficient , increase in thermal efficiency is always linked to steam overheating without having to increase the pressure , since then one gets the same pressure effect with less molecules, wherein making a substantial reduction in the quantity of water needed to be vaporized. The wheels of these four carriages, making twelve wheels in total, ran around the periphery of the engine chamber. For example, one port can serve as an intake from a conventional How the various ports are used depends on whether the automotive engineer wants a traditional internal combustion engine or one that delivers the super-high compression required of photo-detonation. The valves are closed during the combustion process and not in motion.
Because conventional turbines can not be widely modulated in rpm and load, they are not suitable for gas flow and pressure control, while the Quasiturbine is essentially a closed valve at zero rpm, and has high efficiency at all torque and all flow rpm. Quasiturbine publishes « efficiency data » while vane motor manufacturers don't. Quasiturbine is a uniflow engine, with the further advantage of not recompressing any residual steam, resulting in superior energy efficiency. Energy being proportional to the pressure time the volume, energy is weak after each relaxation even if there is pressure, because volume is contracted and weak, and it is the heating which gives again the volume, and thus of energy These multiple relaxations are profitable in the case of systems of several megawatts with high and constant initial pressure having important operating time ratios, but are more difficult to justify in the case of small vehicles asking for a few tens of kW only, where the operating time ratio is half an hour per day, and of which high pressure of the tanks is not constant! For optimum performance, the feed line must be well balanced between the two intake ports, which must be done by ending the line passed the 2 T by an accumulator buffer tank, on which the pressure gage can be located. Instead of using a conventional pressure regulator an energy dissipative device , a pneumatic Quasiturbine will rotate under the pressure differential and the flow will be controlled by the rpm, i. . Premium on « efficient equipment » is rapidely recovered in operational cost.
The wheels of these four carriages, making twelve wheels in total, ran around the periphery of the engine chamber. . First, let's look at the components of simpler Quasiturbine model -- the version without carriages. QUASITURBINE Hand Rotation Test QT5LSC 5 litres Expander up to 12 kW under 4 bar 60 psi The Quasiturbine is a pistonless Rotary Machine using a deformable rotor whose blades sides are hinged at the vertices. This is tens of giant windmills on kW-h basis!. Furthermore, the Quasiturbine recuperates mechanically the gas differential pressure energy, which can be used to run more compressors and make more cold. In the case of thermal solar systems, if the internal liquid reserve is large enough for all the sunshine period, this operation mode needs only one unique fill up at night! Even if the Quasiturbine can accept saturated steam, it is not suitable from the energy efficiency stand point, that this steam stays saturated during all the cycle.
One of these powering a generator in a hybrid may be a nice efficient cheap to run option - like in the Mini. This is the reason for Quasiturbine! If built it would not support photo-detonation. The present possibilities have not yet been tested. The reversibility of a pneumatic system storage worsens with increasing chosen pressure, unless the heat is also stored in the tank at the time of compression storage for short duration and low 10 bar — 150 psi. All experimental demonstration has to be done only by gas experts and under all current rules and regulations. La pression d'un circuit vapeur est déterminer par le point le plus froid condensation , alors que l'éfficacité est donné par la température de la vapeur les surchauffeurs font une chauffe à pression constante - celle du point froid, souvent la chaudière elle-même.
With its compact size, no moving parts and no emissions, the ZiV really is the next step in urban travel. Toroidal engine · Trochilic engine References. Co-generation Saturated Steam The Quasiturbine is an unmatched alternative to saturated steam turbine with modulated power output. Here is Staffan's message: The ONLY solution is to enforce Time is running out:-. And if better exist s, are we going to give it a try? More Technical A A project intended to make a.
Because conventional turbines can not be widely modulated in rpm and load, they are not suitable for gas flow and pressure control, while the Quasiturbine is essentially a closed valve at zero rpm, and has high efficiency at all torque and all flow rpm. The measurement of the exhaust temperature gives generally a good indication of the efficiency, since the minimum of energy lost into the environment correspond to an exhaust temperature equal neither inferior, nor superior to the ambient temperature. None of these solutions are short term stable and competitive. The Enigma looks like an excellent start on a home grown British motorcycle. The old steam engines used up to 3 machines or more stages in the case of turbines , the Titanic had steam engines using 4 stages of relaxations.
Quasiturbine Qurbine : steam engine / air motor / gas expander
Another object is to provide an engine, which has a short pressure peak, cold intake area characteristics, so that it is suitable for photo detonation mode pure hydrogen fuel combustion. . . Steam Quasiturbine could not be at a better time. .
