Building a rotary piston engine

AI Thread Summary
The project focuses on building a 6-inch rotary piston engine featuring an external combustion chamber designed to redirect heat into a rotor housing, allowing for efficient mechanical work conversion. The engine utilizes a piston and crank mechanism to compress an air-fuel mixture, with a rotor that turns 340 degrees before reaching the exhaust port, maximizing energy output. Key specifications include a rotor size of 6 inches in diameter and a housing size of 7 inches in diameter, with a total piston stroke of 20.42 cubic inches. The combustion chamber is engineered to handle pressures up to 150 psi, with a maximum heat pressure exceeding 2000 psi, aiming for a torque output of 3000 in-lb. The project is currently in the initial stages of constructing the housing and rotary assembly.

This project is a basic 6 inch rotary piston engine.

The rotary engine project is to build a external combustion chamber that will redirect the expanding heat into a rotor housing and turn a rotor with a single piston vane 340 degrees to the exhaust port.

The basic piston,rod and crank compresses air/fuel mixture into a chamber that allows the combustion heat energy to move into the rotary housing to spin the rotor.

This is the most efficiency way to convert heat energy into direct output of mechanical work.

I'm at the first stage of building the housing and rotary assy.

This is the data of the housing/rotor

Rotor size: 6"diameter x 2"width...area ((3^2*pi)*2)=56.55cu/in
Housing size: 7" inner diameter x 2" width...area ((3.5^2*pi)*2)=76.97cu/in
Piston vane: .5" x 2" or 1in/sq

The total piston stroke at 360 degrees (((3.5^2*pi)*2)-((3^2*pi)*2))=20.42cu/in or334.62cc
The piston has a 340degree power stroke before it enters the exhaust port and 20 degree after the combustion port, or a total if 320 degree of mechanical work.

(20.42/360deg)*320deg= 18.15cu/in total displacement of mechanical work in the rotary housing.

Combustion chamber is 1 cu/in in area.
Compressor pump 2.5" diameter piston x 2.25 stroke

The combustion chamber is a special design port that stores the max pressure to a limit of 150psi, after combustion of fuels the expanding port is redirected into the rotary housing, that then move the rotor forward.

This is the only engine that can can convert heat energy at TDC, into direct output of torque.


Max heat pressure 2000+psi
max output of torque (1000*3inch crank)=3000in/lb

I don't know what the true output of torque would be when this is finished.

This is what the engine will look like:

Posted June 2024 - 15 years after starting this class. I have learned a whole lot. To get to the short course on making your stock car, late model, hobby stock E-mod handle, look at the index below. Read all posts on Roll Center, Jacking effect and Why does car drive straight to the wall when I gas it? Also read You really have two race cars. This will cover 90% of problems you have. Simply put, the car pushes going in and is loose coming out. You do not have enuff downforce on the right...
I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly
Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'
Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...
