20080302908 | DETACHABLE HYDROFOIL TRIM TABS FOR USE WITH SEAPLANE FLOATS FOR ASSISTING WITH LOWER SPEED ON-PLANE CONDITION AND STABILITY DURING STEP TURNING/CHINE WALK MANUEVERS - A hydrofoil trim tab for use with each of a pair of seaplane floats, each tab including a substantially planar shaped body secured to an inside facing location of each float such that a pair of tab bodies are arrayed in opposing and inwardly directed fashion relative to the floats. Each tab is further constructed as a two piece article, a first portion being either mechanically secured or welded to the surface of the float, with a second portion being releasably/breakaway attached to the first portion, such as by frangible fasteners engaging a slidably connection location between the portions. In this fashion, inadvertent breakage of a trim tab at the frangible location will prevent damage to the float. | 12-11-2008 |
20090302155 | FLOTATION SYSTEMS - Flotation systems including separately packed floats and life rafts are disclosed. Such systems, advantageously used for helicopters or other vessels, attach rafts to exterior covers of the floats. Thus, if not needed, or if maintenance or repair is required, the rafts may be removed from the float covers quickly and easily and without unpacking the floats themselves. Likewise, removal of the rafts permits maintenance to be performed on the floats without any need to unpack the rafts. Also identified are mechanisms for indirectly connecting both floats and rafts to vessels and for independently inflating both floats and rafts using a single actuator. | 12-10-2009 |
20100032522 | Centrally motor driven seaplane thrusters - A centrally motor driven thruster apparatus mounted in to a hull of a float of a seaplane including floatplanes and amphibious aircrafts. The thrusters, either water-jet thrusters or tunnel propeller thrusters are housed within the hull of the floats of a seaplane and provide the seaplane with slow speed maneuvering capabilities while the aircraft is in the water without the use of the on board screw propeller minimizing therefore the risks of damage to properties and/or humans. The thrusters are centrally motor driven sharing a common power unit. The thrusters, either water jet-thrusters or tunnel propellers thrusters, are driven by a common centrally located motor directly or indirectly actuated by the onboard Auxiliary Power Unit. The design and structure of the water-thrusters, either tunnel propellers thrusters or water-jet thrusters encompasses the use of lightweight material such as aluminum and/or fiberglass in order to minimize the addition of weight to the aircraft with the aim of not interfering with the plane aerodynamics during flight including takeoff and landing. | 02-11-2010 |
20100314493 | WINGTIP AND SPONSON INTERACTION ON AN AMPHIBIOUS AIRCRAFT - A system for enhanced lateral stability of an amphibious aircraft includes a buoyancy system laterally displaced from opposite sides of the fuselage of the aircraft and wingtip system having a hydrodynamic planing surface associated with each wingtip. The hydrodynamic planing surface on each wingtip prevents the submersion of an associated buoyancy structure. By supplementing the lateral stability of the buoyancy structures using hydrodynamic planing surfaces, the combined lateral width of the fuselage and buoyancy structures can be reduced without detrimentally impacting operational performance. This reduced lateral width enables the amphibious aircraft to be configured for storage and transportation on a trailer or shipping container. | 12-16-2010 |

20140252165 | Crash Load Attenuator for Water Ditching and Floatation - A flotation device is described herein. The floatation device comprising an air bladder; a girt coupled to the air bladder; and a load attenuator coupled to the girt. The load attenuator is further coupled to an airframe of an aircraft. The float bag is used in water landings of the aircraft. | 09-11-2014 |

20090242697 | VEHICLE WITH BUOYANCY BODIES - According to the invention, inflatable buoyancy bodies are kept in storage housings on the outside of a vehicle. During normal use, buoyancy bodies are folded up and stored under covers. Only when the vehicle is on water do the covers open and buoyancy bodies fill with air. An on-board compressed air system supplies air for filling buoyancy bodies so that air, which is not required by a braking installation or the like of the vehicle, is used to fill the buoyancy bodies. The additional use of outside air enables more air to be supplied to the buoyancy bodies at a low pressure than the sole use of the on-board compressed air system. In order to empty the buoyancy bodies, a vacuum is generated in connection lines. When stop cocks are open, air is sucked out of the buoyancy bodies, which then fold up and the covers are closed and locked. | 10-01-2009 |
20150321757 | MULTI-HULL SEAPLANE - A multi-hull seaplane configured to eliminate most porpoising modes (only the low angle planing remains) by separating the forward and aft hulls and staggering them transversely so as the water flow from the forward hulls does not strike the rear hulls at planing speeds thereby eliminating afterbody induced porpoising. The forward and aft hulls are offset laterally with possible vertical offset and longitudinally to maintain lateral and longitudinal stability over all speed regimes. | 11-12-2015 |

20100230534 | Float pack assembly and method of use - An emergency floatation system for attachment to a helicopter that includes a support frame, a float pack assembly and an inflation system. The float pack assembly includes a float in a packed configuration, a sleeve integrated into the float and a rigid support that at least partially extends through the sleeve. The float pack assembly is configured so that it may be installed and/or removed from the support frame separate from the inflation system. | 09-16-2010 |
20110006157 | ACTUATORS PRINCIPALLY FOR INFLATABLE SYSTEMS - Actuators, principally for inflating emergency-usage objects such as floats and rafts, are detailed. Two opposite positive actions may be required to effect complete inflation of the objects, inhibiting inadvertent deployment of, particularly, the rafts while readily permitting deployment when intended. | 01-13-2011 |
