Rubber Powered Free Flight

A Rubber-Powered Free Flight Airplane is a flying model powered by an elastic band. The elastic band is wound to store kinetic energy. Built carefully, some can stay aloft for forty minutes or longer and can cover hundreds of feet. Today, this activity is educator's first choice for developing appreciation for the technicalities of flight and other scientific principles. Children and teachers can discover and appreciate the usefulness of mathematical principles, scientific principles, problem solving methods and team development through competition.  



 

History of Rubber Power

The Wright Brothers received a simple free flight rubber powered aircraft when they were 8 and 12 years old. This fuelled their fascination for flight and they eventually embarked on a journey resulting in the invention of man made flight.

One of the most important inventions leading up to the invention of the airplane was the rubber-powered airplane. This may seem surprising but its true. In 1871, French scientist Alphonse Penaud astounded members of the French Academy of Sciences by flying a rubber-powered aircraft he called a planaphore for 131 feet. It was the first recorded flight of an inherently stable, heavier than air aircraft.

For the next 50 years, rubber-powered (then called torsion-powered) airplanes were a key  research tool for aerodynamic engineers. It allowed them to test numerous configurations of flying surfaces for airworthiness without having to build full-size airplanes.

Torsion-powered aircraft also became a popular toy in the late 1800s. After Penaud's demontration, toy makers immediately started to create rubber-powered flying toys. One of the most popular of these toys was a torsion-powered helicopter. In 1878, Bishop Milton Wright brought this toy home to his sons Wilbur (age 12) and Orville (age 8) and started them dreaming of flight. It soon wore out, but they made copy after copy. They were still making copies to delight their nieces and nephews in 1903 just before they made their first powered flights in a real airplane.

Amazing But True! Elastic Band Facts

A rubber band is an extremely capable engine for an aircraft, and the science of torsion motors for model airplanes has progressed at the same amazing pace as gasoline and jet engines in real airplanes.

In 1909, as Wilbur and Orville Wright were coming home from a triumphant tour of Europe, the American record for distance flown with a rubber band-powered airplane was just over 200 feet.

In 1916, as World War 1 was at its height, Thomas Hall if the Illinois Model Aero Club flew a model 5337 feet -- over a mile!

In 1924, just a few years before Lindbergh flew the Atlantic, Robert V. Jaros (also from the Illinois Model Aero Club) flew a model 7920 feet in 10 minutes and 14 seconds.

Today, model airplanes in the competitive FID class can fly for more than 40 minutes.
