Air propulsion apparatus with windmill having multiple windmill blades to enhance performance

Abstract

A vehicle driven by at least one motor driven propeller has a windmill apparatus with multiple pairs of blades to enhance power output, lift and propulsion. Several clutches are used to engage and disengage the windmill and the motor.

What is claimed is:  
     
         1 . An air propelled vehicle, comprising: 
 an air propulsion means to propel said vehicle; 
 said air propulsion means having a source of power to drive the air propulsion means;  
   a power transfer means engaging said source of power;    a first clutch means for engaging said power transfer means in a selected condition;    a windmill means to provide enhanced propulsion to said vehicle when engaging said first clutch means in said selected condition.    
     
     
         2 . The vehicle described in  claim 1  further comprising: 
 second clutch means coacting with said source of power to disengage said source of power from driving said propulsion means when said windmill means provides propulsion which exceeds that of the source of power.  
 
     
     
         3 . The vehicle as in  claim 1  further comprising multiple pairs of windmill blades mounted in said windmill means.  
     
     
         4 . The vehicle of  claim 3  wherein the multiple pairs of blades are attached to multiple hubs in said windmill means.  
     
     
         5 . The vehicle of  claim 3  wherein the blades in each pair of windmill blades are interconnected with braces.  
     
     
         6 . The vehicle of  claim 1  wherein the air propulsion means comprises a propeller.  
     
     
         7 . The vehicle of  claim 6  wherein the air propulsion means comprises two propellers.  
     
     
         8 . The vehicle of  claim 1  wherein the source of power is a motor.  
     
     
         9 . The vehicle of  claim 1  where the power transfer means is a shaft.
