Abstract
Abstract Inflatable collars (32,34) are positioned on each side of a downed aircraft (10) and the collars (32,34) are connected by belly bands (80,100) to support the ends (18,20) of the aircraft (10). The bands (80,100) are positioned by positioning straps (90,90') which are attached to the aircraft (10) prior to inflation. The collars (32,34) are also attached to the aircraft (10) at intermediate locations (24,26). The collars (32,34) are divided into separate chambers (44,48,52,54,56,44',48',52', 54',56') so that after inflation the different chambers of the collars (32,34) support the different parts (18,20,22) of the aircraft (10).

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
146 words
An auxiliary flotation system for aircraft downed at sea comprising a first inflatable collar for positioning on the left side of the aircraft, a second inflatable collar for positioning on the right side of the aircraft, supporting means for connecting said first inflatable collar and said second inflatable collar to the aircraft, said supporting means including strap means extending between one end of said first inflatable collar and a corresponding end of said second inflatable collar, positioning means fastened to said strap means and having means for connection to a first end portion of the aircraft for holding said strap means in a position for supporting a predetermined part of the aircraft upon inflation of said first inflatable collar and said second inflatable collar, and means for inflating said first inflatable collar and said second inflatable collar after said positioning means is attached to the aircraft.
Claim 2
Dependent Claim
146 words
An auxiliary flotation system for aircraft downed at sea comprising a first inflatable collar for positioning on the left side of the aircraft, a second inflatable collar for positioning on the right side of the aircraft, supporting means for connecting said first inflatable collar and said second inflatable collar to the aircraft, said supporting means including strap means extending between one end of said first inflatable collar and a corresponding end of said second inflatable collar, positioning means fastened to said strap means and having means for connection to a first end portion of the aircraft for holding said strap means in a position for supporting a predetermined part of the aircraft upon inflation of said first inflatable collar and said second inflatable collar, and means for inflating said first inflatable collar and said second inflatable collar after said positioning means is attached to the aircraft.
Claim 3
Dependent Claim
92 words
The auxiliary flotation system according to claim 1 wherein said supporting means includes a second strap means extending between the other end of said first inflatable collar and a corresponding end of said second inflatable collar, a second positioning means fastened to said second strap means and having means for connecting said positioning means to a second end portion of the aircraft for locating said second strap means in a position for supporting a second predetermined part of the aircraft upon inflation of said first inflatable collar and said second inflatable collar.
Claim 4
Dependent Claim
92 words
The auxiliary flotation system according to claim 2 wherein said supporting means includes a third and fourth strap means connected to said first inflatable collar and said second inflatable collar, respectively, at positions intermediate the ends of said first inflatable collar and said second inflatable collar for supporting an intermediate part of the aircraft, said third and fourth strap means being attached to the aircraft at a position intermediate said position for supporting a first predetermined part of the aircraft and said position for supporting a second predetermined part of the aircraft.
Claim 5
Dependent Claim
47 words
The auxiliary flotation system according to claim 1 wherein said strap means is separable into a single strap connected to said first inflatable collar and a belly band engageable with the aircraft at said predetermined part connected to said second inflatable collar and to said positioning means.
Claim 6
Dependent Claim
88 words
The auxiliary flotation system according to claim 2 wherein said strap means is separable into a single strap connected to said first inflatable collar, a belly band engageable with the aircraft at said predetermined part connected to said second inflatable collar and to said positioning means, said second strap means being separable into a single strap connected to said first inflatable collar and a second belly band engageable with the aircraft at said second predetermined part connected to said second inflatable collar and to said second positioning means.
Claim 7
Dependent Claim
92 words
The auxiliary flotation system according to claim 5 wherein said supporting means includes a third and fourth strap means connected to said first inflatable collar and said second inflatable collar, respectively, at positions intermediate the ends of said first inflatable collar and said second inflatable collar for supporting an intermediate part of the aircraft, said third and fourth strap means .being attached to the aircraft at a position intermediate said position for supporting a first predetermined part of the aircraft and said position for supporting a second predetermined part of the aircraft.
Claim 8
Dependent Claim
52 words
The auxiliary flotation system according to claim 3 wherein at least one of said third or fourth strap means includes a pair of straps fastened to the corresponding inflatable collar at spaced positions and yoke means connecting said pair of straps to a single supporting strap for releasable connection to the aircraft.
Claim 9
Dependent Claim
56 words
The auxiliary flotation system according to claim 1 wherein said first inflatable collar and second inflatable collar are divided into separate chambers with an end chamber at said one end of said first inflatable collar and an end chamber at said corresponding end of said second inflatable collar for supporting said predetermined part of the aircraft.
Claim 10
Dependent Claim
45 words
The auxiliary flotation system according to claim 8 wherein said first inflatable collar and said second inflatable collar have second end chambers at the other ends of said first inflatable collar and said second inflatable collar for supporting said second predetermined part of the aircraft.
Claim 11
Dependent Claim
124 words
The auxiliary flotation system according to claim 9 wherein said first inflatable collar and said second inflatable collar have intermediate chambers between said first end chambers and said second end chambers, said supporting means including a third and fourth strap means connected to said first inflatable collar and said second inflatable collar, respectively, at positions intermediate the ends of said first inflatable collar and said second inflatable collar for supporting an intermediate part of the aircraft, said third and fourth strap means being attached at positions intermediate said end positions for supporting a first predetermined part of the aircraft and said end positions for supporting a second predetermined part of the aircraft so that said intermediate chambers support said intermediate part of the aircraft.
