Systems and methods including various glazing devices are provided for attaching a window structure to a frame of a vessel or vehicle to form a seal therebetween.

Systems and methods for operating an aircraft door including an airstair are disclosed. In one embodiment, the system includes a hinge configured to pivotally couple a lower portion of the door to a fuselage of an aircraft, a lift mechanism and an interlock. The lift mechanism causes a movement of the door relative to the hinge between a lowered position and a lifted position. The interlock is configurable between: a locked configuration where the movement of the door relative to the hinge is prevented; and an unlocked configuration where the movement of the door relative to the hinge is permitted.

A port-hole of an immersed structure, for seeing, from inside the structure in air, to the outside of the structure in water, level with the structure, wherein the face of the port-hole oriented toward the inside of the structure includes at least one flat section forming an angle of 20 to 40° with respect to the face of the port-hole oriented toward the outside of the structure.

A passive generator system for a marine vessel using an intake manifold having an opening at the bottom of the hull of the vessel. The intake manifold tapers to a point at the rear of the opening and extends upward to an intake funnel that reduces down to a conduit. The conduit has a first portion angled relative to the opening which joins to a second portion at an elbow. The second portion of the conduit extends horizontally to a rear of the vessel, to a conduit exit where water can exit the conduit. An impeller is location in the first portion of the conduit that drives a generator through a shaft between the impeller and the generator, the shaft passing through a top of the first portion of the conduit.
