Developed by Dr. Goddard during the late summer and early fall of 1928,
the “Hoopskirt” rocket featured a small rocket engine mounted in the
nose and a system of tanks and alcohol burners—to maintain fuel
pressure—mounted on two legs. On December 26, 1928, the rocket flew
62.33 meters (204.5 feet) in 3.2 seconds—its most successful flight.
Like all Goddard rockets, the “Hoopskirt” burned gasoline and liquid
oxygen.
The “Hoopskirt” rocket is from Mrs. Robert H. Goddard.
