Title:
PROPELLER GUARD FOR UNMANNED MULTI-ROTOR TYPE HELICOPTER AIRFRAME
Document Type and Number:
Japanese Patent JP2016182940
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To solve problems in which a risk at the collision and the crash extremely increases more than a guarded airframe in an airframe not covered by a propeller guard in a situation where the spread of unmanned multi-rotor type helicopters advances rapidly in late years, a propeller is structured to be mounted on a pipe-shaped tip protruded from an airframe center in a current state, and therefore it is necessary to mount the propeller guard separately from the airframe, resulting in weight increase, structure complication and insufficient strength, etc.SOLUTION: A propeller guard is used as an airframe itself, and thereby structural simplification, weight reduction and safety in the collision and the crash are secured. The propeller guard is made the airframe, and thereby the weight reduction, the structural simplification and the safety are secured.SELECTED DRAWING: Figure 1
