Projectile flier

Abstract

A projectile flier has a flying body, a propeller device mounted on the flying body and an actuator detachably combined to the flying body to rotate the propeller device. The flying body has a tube located at its gravity center to rotatably combine with an axis of the propeller device. The actuator has a handle with a pulling device that efficiently drives the axis of the propeller device to rotate. Until the propeller device rotates at high speed to provide efficient floating force, the flying body disengages from the actuator and flies into sky. By efficiently rotating the propeller device with the pulling device, rotation speed of the propeller device is significantly increased to make the flying body fly over a long period and a far distance.

1 . A projectile filer comprising:
 a flying body having a tube mounted at a gravity center of the flying body;   a propeller device rotatably mounted on the flying body and having an axis penetrating the tube of the flying body; and   an actuator detachably engaged with the axis on the flying body and driving propeller device to rotate, the actuator having:   a handle;   a chamber defined in the handle; and   a reeling assembly received inside the chamber to operationally drive the propeller device.   
   
   
       2 . The projectile flier as claimed in  claim 1 , wherein the reeling assembly comprises:
 a rewinding device received inside the handle;   a holding portion rotatably mounted on the chamber and having a recess detachably engaged the axis of the propeller device;   a reel having one end combining the holding portion and another end combining the rewinding device;   a string winding on the reel to operationally drive the reel to rotate; and   a pulling tag attached to a free end of the string.   
   
   
       3 . The projectile flier as claimed in  claim 2 , wherein the rewinding device is a rubber band connected between the reel and a bottom of the handle to provide a restitution force to the reeling assembly. 
   
   
       4 . The projectile flier as claimed in  claim 1 , wherein the propeller device comprises the axis, multiple blades radially attached to the axis and a rim connected to distal ends of the blades to perform a propeller wheel. 
   
   
       5 . The projectile flier as claimed in  claim 1 , wherein the flying body is helicopter-shaped. 
   
   
       6 . The projectile flier as claimed in  claim 1 , wherein the axis of the propeller device further has a middle portion, a neck defined at the middle portion and a fastener mounted at the neck to avoid the propeller device disengaging from the flying body.
