The first ramjet, a 20" diameter model, was constructed almost entirely by hand, with the sheet-metal housing hammered out over the curvature of the curbstone of a nearby street. It was delivered to the Navy in 1945. The newly created

In order to reduce drag and increase lift, the engines were mounted in the trailing edge of the wing, and the craft used "pusher" propellers. Doing so created a problem of removing heat from the engines in flight. Roy and his team solved the cooling problem, and in the process he discovered that the

After completing high school, Roy attended the
Burlington Junior College and taught an aeronautics course while he continued to run a model airplane business to raise money to pay for school. At the age of 20 he dominated the Mississippi Valley model contest, winning the event with an 8-hour 50-mile

As a young boy, Roy was fascinated with flight and designed and flew model airplanes powered by rubber bands. At the age of 12, he was teaching model building at the
Burlington YMCA. Before he was 14 years old, he had designed an airplane that won the St. Lous Model Airplane Meet by flying for over

In 1964, Weldon Worth, Chief
Scientist of the U. S. Air Force Aero Propulsion Laboratory noted "I've always felt that the Air Force got it's dollars worth from Marquardt. There's a company which had a low overhead and an ingenious and resourceful test group. There was lack of friction there, and
