Abstract
Abstract A lightweight, segmented, easily assembled aircraft having a hollow fuselage tube, upon which the cockpit, wing, empennage, landing gear, engine, and shell segments are supported and secured, is presented. The wing construction aerodynamically extends the effective wingspan of the aircraft and stabilizes flight by including an aileron slot, which rams positive pressured air from the lower surface of the wing over the upper surface of the wing to laminarize the turbulent air near the ailerons, and including an end plate, which is toed-in and canted towards the upper surface. A fore shell segment separates from and moves fowardly of a fixed, aft shell segment along a track apparatus, secured to the hollow fuselage tube, to permit access to the cockpit of the aircraft.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
119 words
A segmented, easily assembled aircraft comprising: a hollow, straight, one-piece fuselage tube extending uninterrupted the entire length of the aircraft, a cockpit and a fore shell supported by and mounted upon a fore section of said hollow fuselage tube, a main wing pylon and a main landing gear, and support means supported by and mounted upon said hollow fuselage tube, said support means surrounding said tube, extending laterally from said fuselage tube and securing said landing gear and said main wing pylon to said tube, an empennage assembly supported by and mounted upon the aft section of said hollow fuselage tube, and an engine compartment, a wing, and an aft shell supported by and mounted upon said main pylon.
Claim 2
Dependent Claim
119 words
A segmented, easily assembled aircraft comprising: a hollow, straight, one-piece fuselage tube extending uninterrupted the entire length of the aircraft, a cockpit and a fore shell supported by and mounted upon a fore section of said hollow fuselage tube, a main wing pylon and a main landing gear, and support means supported by and mounted upon said hollow fuselage tube, said support means surrounding said tube, extending laterally from said fuselage tube and securing said landing gear and said main wing pylon to said tube, an empennage assembly supported by and mounted upon the aft section of said hollow fuselage tube, and an engine compartment, a wing, and an aft shell supported by and mounted upon said main pylon.
Claim 3
Dependent Claim
90 words
An aircraft as recited in claim 1 wherein said cockpit contains a track apparatus upon which said fore shell is slidably mounted for forward movement, said track apparatus being operably supported by and mounted upon said hollow fuselage tube by means including a roller received within said tube and a link arm pivotally connected to said roller and protruding from an open front end of said tube and pivotally engaging said fore shell, and guide and limiter means for said link arm within said tube and engaging said link arm.
Claim 4
Dependent Claim
63 words
An aircraft as recited in claim 1 wherein said cockpit has a forward seat, and a rearward seat, said rearward seat being operably mounted and fixed upon said hollow fuselage tube, and said forward seat being operably mounted but slidable upon said hollow fuselage tube for stabilizing the balance of the aircraft in relation to the size of the individual operating the aircraft.
Claim 5
Dependent Claim
124 words
An aircraft as recited in claim 1 wherein the mid-section of said hollow fuselage tube, through said main pylon, supports said engine compartment, said wing and said landing gear apparatus of the aircraft for improving the stability, balance, and maneuverability of the aircraft during all stages of flight by concentrating the center of gravity on said mid-section of said hollow fuselage tube, said engine compartment, said wing, and said landing gear apparatus positioned aft of said cockpit improving visibility forward, upward, downward, and sideward during all stages of flight, and engine powering a pusher propeller, and said pusher propeller and said engine being located above said wing and said fore shell permitting greater air flow against which said pusher propeller may push the aircraft.
Claim 6
Dependent Claim
43 words
An aircraft as recited in claim 1 wherein said wing has a wing tip, an upper surface, a lower surface, an aileron, an end plate at the tip of said wing, and an aileron slot immediately forward of said aileron on said wing.
Claim 7
Dependent Claim
39 words
An aircraft as recited in claim 5 wherein said end plate is toed-in and canted toward the upper surface of said wing for improving the stability of the aircraft during flight and extending the effective wingspan of the aircraft.
Claim 8
Dependent Claim
103 words
An aircraft as recited in claim 5 wherein said aileron slot extends from the lower surface of said wing up through it to the upper surface of said wing immediately forward of said aileron, said slot having a greater sectional surface area at said lower surface of said wing and a smaller sectional surface area at said upper surface of said wing permitting positive pressured air from said lower surface to ram into said slot, and said positive pressure air laminarizing turbulent air above said upper surface of said wing, stabilizing the aircraft during flight and extending the effective wingspan of the aircraft.
Claim 9
Dependent Claim
97 words
An aircraft as recited in claim 1 wherein a track apparatus, supported by and mounted upon said fuselage tube upon which said fore shell slides forwardly from said aft shell for permitting access to said cockpit is provided, said fore shell has roller means for sliding on said track apparatus and bracket means for securing said fore shell to said roller means, said tube housing one track of said track apparatus for one of said roller means, and said tube having a stopper means therein for halting the sliding of said roller means along said one track.
Claim 10
Dependent Claim
29 words
An aircraft as recited in claim 6 wherein said toed-in angle is less than said canting angle toward said upper surface for providing stabilized course direction of the aircraft.
Claim 11
Dependent Claim
49 words
An aircraft as recited in claim 1 wherein said wing has a wing tip, an upper surface, a lower surface, an air deflector member movably positioned on said wing, an end plate at the tip of said wing, and a wing slot immediately forward of said air deflector member.
Claim 12
Dependent Claim
61 words
An aircraft as recited in claim 10 wherein said wing slot extends from the lower surface of said wing to the upper surface of said wing, and said slot having a greater sectional area at said lower surface of said wing than at said upper surface of said wing to increase the speed of movement of air flowing through said slot.
Claim 13
Dependent Claim
53 words
An aircraft as recited in claim 10 wherein said end plate is toed-in and canted toward the upper surface of said wing for improving the stability of the aircraft during flight and extending the effective wingspan of the aircraft, and said toed-in angle is less than said canting angle toward said upper surface.
Claim 14
Dependent Claim
46 words
An aircraft as recited in claim 1 wherein said cockpit area contains a track apparatus upon which said fore shell is slidably mounted for forward movement, said fore shell forms an enclosure, and said track apparatus is operably supported by and mounted upon said fuselage tube.
Claim 15
Dependent Claim
30 words
An aircraft as recited in claim 13 wherein guide and motion limiter means operably connect said fore shell to said fuselage tube to stop forward movement of said fore shell.
