Abstract
A floatation system for attachment to a helicopter landing skid includes a girt dimensioned to be attached to a landing skid and a plurality of floats attached to the elongate girt, wherein the plurality of floats are adapted to be converted from a packed configuration to an deployed configuration, and wherein at least one of the plurality of floats extends beneath the elongate girt when the plurality of floats is in the deployed configuration.
Claims23
An aircraft floatation system comprising:
- a girt;
- and
- a plurality of floats attached to the elongate girt, wherein the plurality of floats are adapted to be converted from a packed configuration to an deployed configuration;
- wherein at least one of the plurality of floats extends substantially beneath the girt when the plurality of floats is in the deployed configuration;
- wherein at least one of the plurality of floats extends substantially above the girt when the plurality of floats is in the deployed configuration;
- wherein at least two of the plurality of floats are of substantially varying sizes.
