Air Ram
The air ram is a pneumatic device that catapults a stunt performer through the air. To simulate the effects of an explosion, the performer steps on a large "pedal" and using compressed air the "pedal" is released sending the performer hurtling through the air. The distance and height the performer attains is dependent upon the air pressure set. There are many different design types, but all air rams have a few design elements in common: They use compressed air and a surface area that the performer steps on—that is raised using the compressed air which then catapults the person forward. At the 1995 (65th) Academy Awards Scientific and Technical Awards presentation, stunt performer Joe Finnegan (a.k.a. Joe Yrigoyen) was the recipient of a Technical Achievement Award for "his pioneering work in developing the Air Ram for motion picture stunt effects."

Pneumatics
Pneumatics (from Greek ‘wind, breath’) is a branch of engineering that makes use of gas or pressurized air. Pneumatic systems used in industry are commonly powered by compressed air or compressed inert gases. A centrally located and electrically-powered compressor powers cylinders, air motors, pneumatic actuators, and other pneumatic devices. A pneumatic system controlled through manual or automatic solenoid valves is selected when it provides a lower cost, more flexible, or safer alternative to electric motors, and hydraulic actuators. Pneumatics also has applications in dentistry, construction, mining, and other areas. Gases used in pneumatic systems Pneumatic systems in fixed installations, such as factories, use compressed air because a sustainable supply can be made by compressing atmospheric air. The air usually has moisture removed, and a small quantity of oil is added at the compressor to prevent corrosion and lubricate mechanical components. Facto ...

Stunt Performer
A stunt performer, often called a stuntman or stuntwoman and occasionally stuntperson or stunt-person, is a trained professional who performs daring acts, often as a career. Stunt performers usually appear in films or on television, as opposed to a daredevil, who performs for a live audience. When they take the place of another actor, they are known as stunt doubles. Overview A stuntman or stuntwoman typically performs stunts intended for use in a film or dramatized television. Stunts seen in films and television include car crashes, falls from great height, drags (for example, behind a horse), and explosions. There is an inherent risk in the performance of all stunt work. There is maximum risk when the stunts are performed in front of a live audience. In filmed performances, visible safety mechanisms can be removed by editing. In live performances the audience can see more clearly if the performer is genuinely doing what they claim or appear to do. To reduce the risk of injur ...
