Flying Toy Aircraft With a Timer Device

Abstract

A flying toy aircraft having one or more low pressure channels acting as the primary lift mechanism. Each of the low pressure channels has a bottom member, two sidewalls, and an optional top member. The interior of the channel can be fitted with an airfoil or a trailing reflexed edge. The aircraft is propelled by propulsion units, which are controlled by a timer device that enables the user to select a predetermined time period for the flight of the aircraft.

I claim: 
     
         1 . A flying toy aircraft comprising:
 one or more low pressure channels defined by a base member and a sidewall having a top, the low pressure channels having a leading section and a trailing section;   a flange member attached to the top of the sidewall and extending outwardly from the low pressure channel;   a propulsion system comprising one or more propulsion units; and   a control system comprising a timer device in operable communication with the one or more propulsion units, the timer device being configured to electrically activate and deactivate the one or more propulsion units.   
     
     
         2 . The flying toy aircraft of  claim 1 , further comprising a first set of wings and a second set of wings, the first set of wings and the second set of wings attached to the low pressure channel, and the first set of wings spaced forwardly of the second set of wings. 
     
     
         3 . The flying toy aircraft of  claim 1 , wherein at least one low pressure channel comprises an airfoil attached to the base member in proximity to the leading section, and a reflexed edge disposed in the base member in proximity to the trailing section. 
     
     
         4 . The flying toy aircraft of  claim 1 , further comprising a rudder member attached to the low pressure channel and disposed within the wake of the one or more propulsion units. 
     
     
         5 . The flying toy aircraft of  claim 2 , wherein the rudder member is the second set of wings, which are attached in adjustable relation to the low pressure channel. 
     
     
         6 . The flying toy aircraft of  claim 1 , wherein at least one propulsion unit comprises contra-rotating propellers. 
     
     
         7 . The flying toy aircraft of  claim 1 , wherein one or more components of the control system are slidably attached to the low pressure channel such that adjusting the location of said components of the control system adjusts the pitch of the aircraft during flight. 
     
     
         8 . The flying toy aircraft of  claim 1 , wherein the low pressure channel further comprises a flexible material that enables the low pressure channel to be curved such that the aircraft follows a predetermined flight pattern determined by the curve of the low pressure channel. 
     
     
         9 . The flying toy aircraft of  claim 1 , wherein the timer device further comprises a control unit, the timer device is operably connected to a selector device, and the selector device is configured to signal the control unit to activate the one or more propulsion units for a predetermined time period. 
     
     
         10 . The flying toy aircraft of  claim 9 , wherein the timer device is configured such that upon receiving a first signal from the selector device the control unit activates a propulsion unit for a first predetermined time period, and upon receiving a second signal from the selector device the control unit activates a propulsion unit for a second time period. 
     
     
         11 . The flying toy aircraft of  claim 9 , wherein the timer device is configured such that upon receiving a signal from a first selector device the control unit activates a propulsion unit for a first predetermined time period, and upon receiving a signal from a second selector device the control unit activates a propulsion unit for a second time period. 
     
     
         12 . The flying toy aircraft of  claim 9 , further comprising a rudder member attached to the low pressure channel and disposed within the wake of the one or more propulsion units. 
     
     
         13 . The flying toy aircraft of  claim 9 , wherein at least one propulsion unit comprises contra-rotating propellers. 
     
     
         14 . The flying toy aircraft of  claim 9 , wherein one or more components of the control system are slidably attached to the low pressure channel such that adjusting the location of said components of the control system adjusts the pitch of the aircraft during flight. 
     
     
         15 . The flying toy aircraft of  claim 9 , wherein the low pressure channel further comprises a flexible material that enables the low pressure channel to be curved such that the aircraft follows a predetermined flight pattern determined by the curve of the low pressure channel. 
     
     
         16 . The flying toy aircraft of  claim 10 , further comprising a rudder member attached to the low pressure channel and disposed within the wake of the one or more propulsion units. 
     
     
         17 . The flying toy aircraft of  claim 10 , wherein at least one propulsion unit comprises contra-rotating propellers. 
     
     
         18 . The flying toy aircraft of  claim 10 , wherein one or more components of the control system are slidably attached to the low pressure channel such that adjusting the location of said components of the control system adjusts the pitch of the aircraft during flight. 
     
     
         19 . The flying toy aircraft of  claim 10 , wherein the low pressure channel further comprises a flexible material that enables the low pressure channel to be curved such that the aircraft follows a predetermined flight pattern determined by the curve of the low pressure channel. 
     
     
         20 . The flying toy aircraft of  claim 11 , wherein one or more components of the control system are slidably attached to the low pressure channel such that adjusting the location of said components of the control system adjusts the pitch of the aircraft during flight.
