A method of treating an aircraft transparency includes applying a water repellant coating composition over a surface of an aircraft transparency substrate, the water repellant coating composition includes a non-chlorinated perfluoroalkylalkylsilane and/or a non-halogenated polyorganosiloxane. The method can include applying a primer composition having an organic solvent and a silicon material over the aircraft transparency substrate to form a primed substrate surface; applying the water repellant coating composition over the primed substrate surface; and heating the water repellant coating composition to form a water repellant coating.

An aircraft fuselage body is constructed of an upper body section having a curved cross-section configuration and a lower body section having a curved cross-section configuration. The upper body section and the lower body section are joined together to form an aircraft fuselage body by splice straps that are secured, end to end along interior surfaces of the upper body section and the lower body section. The aircraft fuselage body being constructed of an upper body section and a lower body section enables installation of systems separately into the upper body section and the lower body section prior to the upper body section and lower body section being joined together.

A passenger window shade on an aircraft is provided. The passenger window shade includes a first section of the passenger window shade. The first section forms a substantially flat and thin plane. The first section has a first transparency to visible light. The passenger window shade includes a second section of the passenger window shade situated within the first section. The second section includes a second transparency to visible light that is different from the first transparency such that an image is formed inside the aircraft when visible light is aimed at the passenger window shade from outside the aircraft.

A low noise aircraft comprising a fuselage comprising a nose section, a cabin and a tail comprising an empennage, the profile of the fuselage tightening towards the tail, two wings mounted on opposite sides of the fuselage, two engines, each engine mounted on a pylon on a respective side of the fuselage, two propellers, each propeller joined to and positioned behind a respective the engine, at least one cabin door to access the cabin, and landing gear, wherein the engines are positioned above the wings, wherein the propellers are positioned at a rear end of each engine such that the propellers push the engines, and wherein the propellers are positioned behind the inhabitable zone of the cabin.

An in-flight impact protection system for aircraft. An aircraft having a panel, with a sensor disposed on the aircraft and adapted to transmit a signal and receive a reflection of the signal. A controller coupled to the sensor and adapted to receive the reflection from the sensor to determine whether an object is near the aircraft's panel. An inflation device, which includes a tube member, is coupled to the controller and positioned inside the aircraft, proximate the panel. After determining that the object is near the panel, the controller can activate the inflation device so that the tube member inflates, thereby buttressing at least a portion of the panel. The panel can be a windshield, fuselage member, or other suitable component.

Commercial supersonic aircraft and associated systems and methods. A representative commercial supersonic aircraft includes a fuselage configured to carry a crew and between 20 and 60 passengers, a delta wing mounted to the fuselage, and a propulsion system carried by at least one of the wing and the fuselage, the propulsion system including a plurality of engines, at least one variable-geometry inlet, and at least one variable-geometry nozzle.

A mold for casting a polymeric aircraft window panel includes a first mold half (12) having a first mold surface (24), and a second mold half (14) having a second mold surface (50). The first mold surface (24) and/or the second mold surface (50) have a shape conforming to a final shape for the major surfaces of the aircraft window panel. The first mold half (12) and/or the second mold half (14) can be formed of rolled, hydroformed, or stamped metal.

A network system for monitoring and storing data of aircraft intelligent windows or windshields to provide useable life of, provide real life performance of, and/or measure characteristics and/or properties of, the windshields forwards the data from sensors mounting the windshield to a window sensing hub having a microprocessor programed to receive and process the data to determine the performance of the windshield and formatting the data in accordance to a preset program, wherein the program includes providing data from the sensors that measures characteristics and properties of the windshield that are active during the period in which the data is taken. An aircraft central maintenance system connected to the window sensing hub receives the formatted information from the window sensing hub and unfiltered or unformatted information, wherein the unfiltered information from the windshield is acted on by the central maintenance system to provide an estimated useable life of the windshield.
