Abstract
Abstract The aircraft has an A-frame-like strut cantilevered forward from the leading edge structure of each wing of the same. The transom of the strut is arch-like in configuration and has an engine suspended therefrom, within the inside concave recess thereof. The engine is enclosed in a cylindrical nacelle on the transom, and the strut is upwardly canted from the structure of the wing so as to elevate the transom and the nacelle to a level at which the engine exhausts over the wing.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
64 words
In combination, a winged aircraft having an A-frame-like strut cantilevered forward from the leading edge structure of each wing thereof, said strut comprising a pair of forwardly cantilevered beams and an inverted U-shaped transom interconnecting the forward end portions of the beams, and an engine for the aircraft suspended from the transom portion of the strut within the inside concave recess of the transom.
Claim 2
Dependent Claim
64 words
In combination, a winged aircraft having an A-frame-like strut cantilevered forward from the leading edge structure of each wing thereof, said strut comprising a pair of forwardly cantilevered beams and an inverted U-shaped transom interconnecting the forward end portions of the beams, and an engine for the aircraft suspended from the transom portion of the strut within the inside concave recess of the transom.
Claim 3
Dependent Claim
21 words
The combination according to claim 1 wherein the engine is enclosed in a cylindrical nacelle which is carried on the transom.
Claim 4
Dependent Claim
38 words
The combination according to claim 2 wherein the strut is upwardly canted from the structure of the wing so as to elevate the transom and the nacelle to a level at which the engine exhausts over the wing.
Claim 5
Dependent Claim
33 words
The combination according to claim 2 wherein the nacelle surrounds the transom, and the transom assumes a part cylindrical outer configuration which mates with the inner configuration of the nacelle at the top.
Claim 6
Dependent Claim
30 words
The combination according to claim 2 wherein the transom is formed by a cage-like series of arcuate ribs aligned with one another along an axis extending chordwise of the wing.
Claim 7
Dependent Claim
66 words
The combination according to claim 5 wherein the strut has an upward cant in relation to the structure of the wing so as to elevate the transom and the nacelle to a level at which the engine exhausts over the wing, and the ribs are truncated in a transverse plane angled to the axis of the series of ribs at the upward cant of the strut.
Claim 8
Dependent Claim
26 words
The combination according to claim 6, wherein the beams are cantilevered from the leading edge structure of the wing in the transverse plane of the ribs.
Claim 9
Dependent Claim
61 words
The combination according to claim 7 wherein the rearmost rib in the series of ribs, is spaced ahead of the leading edge of the wing, and the forward ends of the beams are bulkheaded into the ends of said ribs, but have portions thereof which extend forward of said rib and interconnect the series of ribs in the transverse plane thereof.
Claim 10
Dependent Claim
28 words
The combination according to claim 5 wherein the ribs are interconnected by a gantry beam at the top thereof, and the engine is suspended from the gantry beam.
Claim 11
Dependent Claim
56 words
The combination according to claim 9 wherein a portion of the engine is disposed forward of the series of ribs, the gantry beam has a jib extending forward from the forward end thereof, and the nacelle surrounds the transom and has a section at the forward end thereof which is supported on and about the jib.
Claim 12
Dependent Claim
25 words
The combination according to claim 2 wherein the nacelle has a bucket-like thrust reverser cowling member defined therewithin, adjacent the leading edge of the wing.
Claim 13
Dependent Claim
81 words
In combination, a winged aircraft having an A-frame-like strut cantilevered forward from the leading edge structure of each wing thereof, said strut comprising a pair of forwardly cantilevered beams and an inverted U-shaped transom interconnecting the forward end portions of the beams, a nacelle carried on the transom, and an engine for the aircraft enclosed within the nacelle, and suspended from the strut below the transom and the upper side of the nacelle, within the inside concave recess of the transom.
Claim 14
Dependent Claim
81 words
In combination, a winged aircraft having an A-frame-like strut cantilevered forward from the leading edge structure of each wing thereof, said strut comprising a pair of forwardly cantilevered beams and an inverted U-shaped transom interconnecting the forward end portions of the beams, a nacelle carried on the transom, and an engine for the aircraft enclosed within the nacelle, and suspended from the strut below the transom and the upper side of the nacelle, within the inside concave recess of the transom.
Claim 15
Dependent Claim
24 words
The combination according to claim 12 wherein the nacelle surrounds the transom and the engine is suspended from the strut independently of the nacelle.
