Description of Operation:
Mobile of Roots blower operation of; http://www.mekanizmalar.com/roots2.html
This 'engine' consists of a power source and integral speed reduction.
It is located on the same axis as two counterrotating rotors and is positioned between the rotors. [Pinion A] drives a [Ring gear A] (not shown) that is directly attached to the lower rotor. [Pinion B] drive a [Ring gear B] (not shown) that is directly attached to the upper rotor. No additional speed reduction is required.
As an alternative, The motor could be located below the two rotors. In this arraignment the two ring gears would be attached to two masts that went up to thier respective motors.
Method A: Water <--> Steam
- High temperature water is metered into the high-pressure area, where it is immediately converted to steam. The pressure is exerted against lobes of the Roots type gears. It rotates the eight Root gears marked 'Lobe A' in a CCW direction and the eight Root gears marked 'Lobe B' in a CW direction. Lobe gear A is connected to a lower pinion gear A and lobe gear B is connected to upper pinion gear B.
- This means that all eight lower pinions rotate counter clockwise. About these eight pinions and in contact with them is an internal ring gear and it will rotate CCW, at a slower rotational speed. . The internal ring gear is directly connected to the lower rotor, which also rotates CCW. Conversely, the upper rotor is drive CW, and identically by the upper pinions and upper internal ring gear.
- The spent steam is gathered in the collector, converted to water and then re injected in a metered amount back into the high-pressure area.
- The heat required to convert the water to steam may come from any device that is capable of converting stored energy into heat.
Method B: Combustion
- Two, or more, elements are converted into a gaseous state in or before the high-pressure area. This gas drives the lobes as per method A. The gas is then exhausted to atmosphere, or alternatively, passed down and out of the blades, thereby providing some additional rotational force.
- Could the gasoline and air be combined, compressed and ignited by a chamber that works similar to a tuned exhaust or by a type of 'engine' which consists of two pistons on a common connecting rod in a common cylinder firing on a two-stroke basis.
Method C: Combined Combustion plus Water <--> Steam
- Can water be introduced into the high-pressure area wherein it is turned into steam. The combined gas and steam create the pressure, which drives the lobes. The fuel flow and the water flow are adjusted to provide the desired power while also optimizing the expansion of the combined gas and steam for the minimum expenditure of fuel and water. To reframe this; ~ the intent is to maximize the power while minimizing the heat loss.
- The final work of the expended gas and condensing steam might be that of taking the water up to a temperature just be low that of its conversion to steam.
- Another possibility is that of reintroducing condensed water back into the 'water tank'. This condensing steam may also reduce the back preasure on the lobes.
Method D: Compressed gas
- A carbon filament wound cylinder that discharges a gas or air via a regulator into the high-pressure area.
See air car on web.
Perhaps the gas that has exited the 'engine' can pass into the blade to drive a cold tip jet or root jet.
Perhaps this gas that has exited the 'engine' can be used to provide flight-control,
Supporting Information for Methods A, B and C:
Detailed Information:
(rough working notes ~ 'cause I've got a lot to learn)
A circulatory system. Consider having the following three zones.
- Expansion zone:
The liquid is injected at a controllable rate and converted to a gas by a heater. It is then ejected by driving the lobes.
- Contraction zone:
(collector) The pressure of this zone is regulated to control the rate of condensation. The liquid is injected into the Intermediate zone.
- Intermediate Zone:
The temperature and the pressure of the liquid is increased in preparation for re injection into the expansion zone. This zone is probably necessary because the boiling temperature is above the surrounding temperature. A thought ~ the more that this 'system' can be isolated from the surrounding temperature. the more ....????....
The idea (hope) is to continually convert the substance between a liquid state and a gas state, while minimizing the amount of energy required to do this. I.e. the smallest temperature differential.
Changes of State:
- Other liquid/gas substances (what is the correct word?) should be considered.
Physical properties of gases
- The surfaces of the lobes must be coated in a material that has low heat absorption. Perhaps boron might do. This is necessary so that the lobes do not cool when on the discharge side and then cause some of the gas to condense on them when on the pressure side.
- The change between the boiling temperature and the condensation temperature.
the melting point and boiling point at normal air pressure
Could an automotive injector be used to vaporizes 'the liquid' and spray it onto a heated surface, which will immediately boil the vapor?
Possible weird thought; If the 'substance' were capable of having a boiling point near room temperature then would the work to convert it to a gas and the work to convert it to a liquid be quite similar ?????
Electricity:
It would probably be ridiculous to use electricity to heat the 'substance'. Just use the electricity directly to drive an electric motor.
Sterling Engine:
- Would a Sterling Engine provide the high-pressure gas for the engine on this page? See this file; 1311.pdf From Pascal.
Potential Advantages:
- The weight should be less than that of an internal combustion engine, transmission and power train.
- ???
Potential Disadvantages:
Homologous 
. Method:
Alternative:
Mentioned by quadrirotor on Rotary Wing Forum.
The two ideas represent opposite approaches. High pressure & low velocity versos low pressure & high velocity.
The turbine will require the additional weight and moving parts of a 2 or 3 stage reducer, plus the gearing to drive the other counter-rotating rotor.
