Self-adapting escape slide
First Claim
1. An inflatable slide, comprising:
- a primary inflatable slide segment;
a means for supporting the primary inflatable slide segment, the support means attached to the primary slide segment and adapted to extend from the primary slide segment vertically downward to provide support when inflated, at least one additional slide segment attached to the primary slide segment such that the primary slide segment and at least one additional slide segments together define a slide length when inflated, and further wherein the additional slide segments increase the slide length when inflated;
a state sensor configured to determine an attitude slide;
an inflation gas source coupled to the primary and at least one the additional inflatable slide segments; and
, an inflation controller in communication with the inflation gas source and the state sensor to cause the gas source to inflate one or more of the at least one additional slide segments as a function of the attitude measured by the state sensor, thereby increasing the slide length.

Abstract
The present invention comprises a system for determining and adjusting the angle at which an escape slide is oriented. The system comprises an inflatable slide having a primary inflatable slide segment and at least one additional slide segments attached to the primary slide segment. Additionally, a state sensor configured to determine the attitude of the slide when inflated is attached to the slide or to structure surrounding the slide. Further, the system includes an inflation gas source coupled to the primary and at least one additional inflatable slide segments and an inflation controller in communication with the inflation gas source and the state sensor. The gas source and the state sensor operate to cause the gas source to adjust the at least one additional slide segments as a function of the attitude measured by the state sensor.

10. An aircraft escape slide, comprising:
-
a primary inflatable slide segment having a top side, a bottom side, a first end and a second end, the first end attached to an aircraft access point;
an inflatable slide support segment attached to the bottom side of the primary slide segment and adapted to extend from the bottom side of the primary side segment vertically downward to provide support when inflated;
at least one additional slide segment attached to the primary slide segment adjacent the second end of the primary slide segment, such that when inflated the primary slide segment and the at least one additional slide segments together define a slide length and further wherein the additional slide segments increase the slide length when inflated;
a state sensor configured to determine the attitude of the aircraft at the aircraft access point and the number of the additional slide segments to be pressurized in order to achieve a desired slide angle;
an inflation gas source coupled to the primary and at least one additional inflatable slide segments; and
the slide support segment and,an inflation controller in communication with the inflation gas source and the state sensor to cause the gas source to automatically pressurize the slide support segment the primary slide segment and one or more of the at least one additional slide segments as a function of the attitude measured by the state sensor, thereby increasing the slide length. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A method of deploying an aircraft escape slide, comprising:
-
deploying a slide attached to an aircraft, the slide having a primary inflatable slide segment attached to a plurality of additional slide segments permanently attached to the primary inflatable slide segment, wherein the additional slide segments increase the slide length when inflated;
activating a timing device or pressure sensor;
waiting a pre-determined time or until a pre-determined pressure is achieved;
determining a slide angle;
determining if the slide angle is within operating slide angle tolerances;
adjusting the slide angle, if necessary, via pressure control within the at least one additional slide segment in order to bring the slide angle within operating tolerances and deploying a slide support segment to provide vertical support for the primary slide segment. - View Dependent Claims (20)
