if the thickness(diameter) of A is same to B while they work, double-loop B is stronger than A . as long as you analyse the force that each rope section bear.
As for double times, I do n't think it is definite. We should consider the friction,and others factors.
Recently I think we can simplify the engine, the compressor will be cancelled, replaced with a fan or a pipe. The inlet gas pressure before combustion will decrease a lot and the total efficiency will be smaller definitely.
After studying the principle and designing the structure carefully...
Thank for your reply.
Though there is a little words in your reply which I can’t understand, I try to explain as possible as I can.
If I design the engine with one pair combustion chambers, one pair outlet pipe, the problem you worried will happen probably. But I design it with several pairs...
I have stated the functions of the branch pipes for the output gas,A reader ever mentioned the front door of the chambers is a importent one. Turly!
I summarized the three main functions of the front door. They must be realized.
1, As the passage for the input gas which let the streams of...
I always think of how to expand the use of the engine,recently I think over if it can be used as the jet engine on the rocket flying in atmosphere.Because in this field engines usually are used once, the engine neednt those reinforcement parts, the engine will be much lighter.
Compared with...
For years I always hope to find a way to estimate the time spent for each work course: combustion, spouting out off the chambers, exchange gases by suction (fresh gas and burnt gas) in chambers.
According to the data from some manuals about the internal combustion engine, I know the combustion...
I have to compensate a little.
There is a sentence in the upper derivation "I set the pressure before turbine same as it after compressor. You can the same description appear in #9 floor. You can refer to it.
I try to calculate the temperature before the turbine:
Pls see below figure 4: the figure show how I find their relationship of the main parameters in different course. (Sometimes I call constant-volume combustion type as closed combustion type)
Normally the pressure after compression is...
Zoraxdoom：
“Thus, Thrust can be taken as proportional to (Pressure/Temperature) * (Square root of Temperature) * (Square root of Temperature).”
Personally I think the conclusion is not very proper, because "Speed of Airflow through the engine is proportional to the square root of temperature."...
Continue to discuss the feasibillity,
Now I discuss the the structure and function of exhaust system, that including the branch pipes, general pipe and turbine.
The branch pipe, general pipe,the turbine install behind the chambers.
The function of branch pipes behind the chambers:
because I...
Thank you for the concerns. I try to answer your questions:
“How do you plan on injecting the fuel and air in the rotating chambers? Moreover how do you plan to make it so that it can be considered pre-mixed?”-----Do you know the old type internal combustion engine on gasline? I plan to use...
Hi,oatlids
when I published the idea including the structure of the engine on other website. Somebody ever reminded me it is like wave rotor engine. I search the wave rotor engine from internet. I think they are different.
the structure are similar, part of principle are same. but the input...
StorminMatt, you also mentioned the heat and cool solution, here I just explain a little of the solutions.
In this engine the flow is more easy to control precise than the current engine because of the doule walls and branch pipes system. We can release a little air from the front door to form a...
As to the seal on the flat surface, I know it is difficult. I make the seal a little flexible and with proper contact surface so that it can adjust itself with chambers deformation.
Even though there is a little gas leak, as long as the composition is not serious, this part of gas will not...
As you mentioned "fatigue damage". I also noticed it and try to decrease the risk. I adopt proper structure to improve their force condition.
for example, I arrange these chambers on a circle position. thus the force on one chamber can be borne by all chambers. the deformation will become...
