LH7 Approximately 10’ diameter, 5 hp, weighing 10 lbs when photographed
Abstract: This invention demonstrates a motorized Frisbee, where direction is forced upon the center axis running perpendicular to the earth, under a saucer shaped balloon. The aircraft uses a rotating buoyant, inflatable wing that creates stability and lift. The spinning envelope reduces forward drag when revolutions increase. This model in the above photo represents a technology at its primitive state, laying foundation for intellectual property.
Objective: Develop a tough all weather aircraft, economical to build, fly and maintain, safe and easy to fly, long flight duration and large payload capabilities.
Development: Seven working models have flown using model aircraft motors and radio control hardware. Balloons where built with polyethylene film and filled with helium. The seventh model, the LH7 uses a 30cc diesel motor, spinning a 16” three bladed prop with a helium filled polyethylene balloon. Plans for the eighth model uses hot air for buoyancy augmented with the heat generated from the turboprop motor or motors.
LH7 Characteristics: The photo was taken 11/11/07 its’ maiden flight. The aircraft is safe because the prop is housed with the exposure underneath the craft. Air flow is drawn up then out perpendicular from prop flow. Little ground disturbance occurs. LH7 flew safely around people, buildings and trees. The craft is simple to operate. Flying the LH7 is like flying a kite without a string.
Markets: As a UAV; Military, Civil, Weather/Science, Agricultural, Search and Rescue, Home Land Security, Utility Vehicle to name a few.
Goals: Break the speed record of lighter than air and buoyant aircraft. Break economy record for controlled flight.
