Abstract
Abstract A simulated non-compressive type fan jet airplane with a cage at the center of the fuselage and a propeller in the cage that draws air rearwardly to thrust the airplane forward. The propeller is driven by a small electric motor and rechargeable electric batteries that are located in the fuselage of the airplane.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
69 words
A free flight simulated fan jet airplane comprising: a fuselage having at least one opening located in proximity of the longitudinal center of said fuselage; a propeller rotatably mounted within said fuselage in near proximity of said opening of said fuselage; and electrical means coupled to said propeller for rotating said propeller to thereby draw air through said opening and to direct said drawn air rearwardly of said propeller.
Claim 2
Dependent Claim
69 words
A free flight simulated fan jet airplane comprising: a fuselage having at least one opening located in proximity of the longitudinal center of said fuselage; a propeller rotatably mounted within said fuselage in near proximity of said opening of said fuselage; and electrical means coupled to said propeller for rotating said propeller to thereby draw air through said opening and to direct said drawn air rearwardly of said propeller.
Claim 3
Dependent Claim
23 words
An airplane as recited in claim 1 wherein said electrical means includes an electric motor having a shaft directly coupled to said propeller.
Claim 4
Dependent Claim
25 words
An airplane as recited in claim 2 wherein said electrical means further includes at least one rechargeable electric battery electrically connected to said electric motor.
Claim 5
Dependent Claim
21 words
An airplane as recited in claim 1 wherein said opening of said fuselage lies both forwardly and rearwardly of said propeller.
Claim 6
Dependent Claim
32 words
An airplane as recited in claim 1 wherein said fuselage includes air flow control means located to the rear of said propeller for directing said rearwardly air flow downwardly of said fuselage.
Claim 7
Dependent Claim
37 words
An airplane as recited in claim 5 wherein said air flow control means of said fuselage is open on the bottom and includes side portions and a progressively downward directed portion for establishing said downward air flow.
Claim 8
Dependent Claim
65 words
An airplane as recited in claim 1 which further comprises: a cage having a forward end, a rear end, and a plurality of longitudinal ribs and associated openings extending between said forward and rear ends; means for mounting said cage in said fuselage in near proximity of said centrally located opening of said fuselage; and means for mounting said electrical means partially within said cage.
Claim 9
Dependent Claim
28 words
An airplane as recited in claim 7 wherein said propeller is located within said cage and is partially shrouded by said plurality of longitudinal ribs of said cage.
Claim 10
Dependent Claim
72 words
An airplane as recited in claim 7 wherein said fuselage includes a plurality of longitudinally extending openings located on the top surface and partially on the side surface of said fuselage in proximity of the longitudinal center of said fuselage, and said cage is mounted within said fuselage so as to align a portion of said associated openings of said cage with said respective plurality of longitudinally extending openings of said fuselage.
Claim 11
Dependent Claim
19 words
An airplane as recited in claim 9 wherein said fuselage is open on the bottom side of said cage.
Claim 12
Dependent Claim
29 words
An airplane as recited in claim 10 wherein the majority of air drawn into said cage enters via said plurality of openings located on the periphery of said cage.
Claim 13
Dependent Claim
72 words
A free flight simulated fan jet airplane comprising: a fuselage having a plurality of openings located in its approximate midsection; a non-compressive electrically powered propeller located in immediate proximity of said plurality of openings of said fuselage; and shrouded means for housing and protecting said non-compressive electrically powered propeller, said shrouded means being mounted to said fuselage and having a plurality of openings aligned with said plurality of openings of said fuselage.
Claim 14
Dependent Claim
72 words
A free flight simulated fan jet airplane comprising: a fuselage having a plurality of openings located in its approximate midsection; a non-compressive electrically powered propeller located in immediate proximity of said plurality of openings of said fuselage; and shrouded means for housing and protecting said non-compressive electrically powered propeller, said shrouded means being mounted to said fuselage and having a plurality of openings aligned with said plurality of openings of said fuselage.
Claim 15
Dependent Claim
38 words
An airplane as recited in claim 12 wherein said non-compressive electrically powered propeller is powered by an electrical motor and at least one rechargeable electrical battery mounted to said shrouded means and located in front of said propeller.
Claim 16
Dependent Claim
44 words
An airplane as recited in claim 12 wherein said propeller is rotated so as to draw air through said respective plurality of openings of said fuselage and said shrouded means and to further direct said drawn air rearward of said propeller and shrouded means.
Claim 17
Dependent Claim
40 words
An airplane as recited in claim 14 wherein said fuselage further includes a member located to the rear of said propeller, said member progressively sloping downward as it extends to rear so as to direct said rearwardly directed air downward.
