The invention relates to an emergency oxygen device for passenger of an aircraft, including a chemical oxygen generator including a chemical oxygen source and an activation unit for initiating a chemical reaction of the chemical oxygen source producing oxygen, at least two oxygen masks each connected with the chemical oxygen generator for receiving an oxygen fluid flow from the chemical oxygen generator after the activation unit has initiated the chemical reaction, and a mechanical activation assembly for activating the activation unit. The activation unit is activated by a mechanical force exerted onto an activation element of the activation unit and the mechanical activation assembly includes for each of the at least two oxygen masks a first mechanical connection from the activation element to a fixation element releasably mounted to the emergency oxygen device and a second mechanical connection from the fixation element to the oxygen mask.

One embodiment of the present disclosure is a unique airborne electrical power and thermal management system. Another embodiment is a unique aircraft. Other embodiments include apparatuses, systems, devices, hardware, methods, and combinations for aircraft and electrical power and thermal management systems. Further embodiments, forms, features, aspects, benefits, and advantages of the present application will become apparent from the description and figures provided herewith.

An aircraft may include at least one secondary power system requiring secondary power, at least two main engines, and at least three non-propulsive utility power (NPUP) generation systems. The NPUP generation systems may each be configured to provide full-time secondary power during operation of the aircraft. The NPUP generation systems may be configured to provide at least a portion of the secondary power required by the secondary power system.

The present invention provides a dewatering device for an air-conditioning system of a plane, comprising: one or more filter plates disposed within a mixing cavity of an air-conditioning system of a plane, for filtering liquid-state water in mixed air in the mixing cavity, wherein the filter plates are configured to be inclinable relative to an axis of the mixing cavity, and an inclination angle thereof is adjustable so as to change a filtering amount of the mixed air.

An air gasper (air) for a vehicle includes an air inlet (26), a first housing (24) disposable through a panel in the vehicle (12), the first housing (24) being connected to the air inlet (26), a second housing (70) disposed within the first housing (24), an air outlet (72) disposed within the second housing (70), downstream of the air inlet (26), and a first mechanism (102, 70) connected between the first housing (24) and the second housing (70). The first mechanism (102, 70) permits the second housing (70) to be stowed within the first housing (24) in a stowed position and also permits the second housing (70) to extend outwardly from the first housing (24) in a deployed position.

An engine bleed control system for a gas turbine engine of an aircraft is provided. The engine bleed control system includes an engine bleed tap coupled to a fan-air source or a compressor source of a lower pressure compressor section before a highest pressure compressor section of the gas turbine engine and a turbo-compressor in fluid communication with the engine bleed tap. The engine bleed control system also includes a controller operable to selectively drive the turbo-compressor to boost a bleed air pressure as pressure augmented bleed air and control delivery of the pressure augmented bleed air to an aircraft use.
