2. DYNA-CAM ENGINE

3. The Dyna-Cam engine is a type of Reciprocating engine that replaces the common crank shaft with a circular plate.

4. An alternate design replaces the plate with a sine-shaped cam, and is thus known as a cam engine

9. CRANKSHAFT

10. WORKING Pistons press down on the plate in sequence
forcing plate to nutate around its center
This motion can be simulated by placing a disc on a ball bearing at its centre
It press down at progressive places around its circumference
The plate is typically geared to produce rotary motion

12. Macomber marketed one of the first axial internal-combustion engines.
it had seven cylinders and a variable compression ratio.
Ignition was supplied by a Bosch Magneto directly driven from the cam gears.
The engine was claimed to be able to run at 150 to 1,500 rpm. It weighed 230 pounds (100 kg) and it was 28 inches (710 mm) long by 19 inches (480 mm) in diameter.

13. Statax
Only a single prototype was produced, which is currently held in the science museum, London
In 1914 introduced series of engine, a 3 cylinder of 10 hp, a 5 cyl of 40 hp, a 7 cyl of 80 hp, and a 10 cyl of 100 hp.
Much improved versions were introduced by Statax's German division in 1929

14. Michell
Its unique feature was the means of transferring the load from the pistons to the swashplate
It is achieved using tilting slipper pads sliding on a film of oil.
mathematical analysis of the mechanical design
In 1920 established the Crankless Engines Company
produced working prototypes of pumps, compressors, car engines and aero engines, all based on the same basic design.
The largest Michell crankless engine was the XB-4070, a diesel aircraft engine Consisting of 18 pistons, it was rated at 2000 horsepower and weighed 2150 pounds.

15. J.O. Almen
Experimental barrel engines for aircraft use were built and tested
The A-4 had much smaller frontal area than water-cooled engines of comparable power output
It was rated at 425 horsepower (317 kW), and weighed only 749 pounds (340 kg),
giving a power/weight ratio of better than 1:2, a considerable design achievement at the time.

16. Heraclio Alfaro designing, building, and flying Spain's first airplane
developed a barrel engine for aircraft use which was later produced by the INDIA motorcycle company as the Alfaro
it included a sleev valve system based on a rotating cylinder head

17. Bristol it was a 7 litre, 9 cylinder, wobble-plate type engine
It was originally conceived as a power unit for buses
its compact format would allow it to be installed beneath the vehicle's floor
The engine had a single rotary valve to control induction and exhaust

18. Wooler the most refined of the designs
It was similar to the Bristol axial engine but had two wobble-plates
driven by 12 opposed pistons in 6 cylinders
The engine is often incorrectly referred to as a swashplate engine.

19. H.L.F Trebert
small barrel engines were produced for marine usage

21. Dyna-Cam
The Dyna-Cam engine originally came from a design by the Blazer brothers, who worked for Studebaker in 1916
It has 6 double-ended pistons working in 6 cylinders, and its 12 combustion chambers are fired every revolution of the drive shaft
The pistons drive a sine-shaped cam, as opposed to a swashplate or wobble-plate

22. Fairdiesel engines which use non-sinusoidal cams
industrial applications and aviation use. Their designs range from a 2-cylinder, 80mm bore engine to a 32-cylinder, 160mm bore one.

23. Applications
The most well-known application is in topedo, where the cylindrical shape is desirable. The modern mark48 torpedo is powered by a 500 hp swashplate engine geared to a pump-jet propulsor. It is fueled by otto fuel II, a monopropellant that requires no oxygen supply and can propel the torpedo at up to 65 knots (120 km/h) (74.56 mph)
Other applications include pneumatic and hydraulic motors,hydrostatic transmissons such as honda's Hondamatic cvt , and air conditioner pumps. Also, some striling engines use a swashplate arrangement, e.g. Stirling Thermal Motors' STM engine
