An aircraft having a static air inlet system. The static air inlet system comprises a static air intake, the static air intake having a through opening formed in a top structural assembly, the through opening forming an interface between a medium and an inside space of the top structural assembly. The static air inlet system has at least one separator subdividing the through opening into at least two distinct slots, the separator comprising a first portion extended by a second portion, the first portion extending inside the inside space and the second portion extending outside the inside space.

An air intake unit for an engine of an aircraft; the intake unit has: a tubular housing; a first inlet opening which is obtained through an outer wall of the tubular housing and through which external air can be taken in; an air filter which engages the first inlet opening; a second inlet opening which is obtained through the outer wall of the tubular housing and through which external air can be taken in; a shutter device which is coupled to the second inlet opening and is movable between a closed position, in which it closes the second inlet opening, and an open position, in which it sets the passage through the second inlet opening free; and an actuator, which moves the shutter device.

A system and method of an airflow control system for a vehicle is described herein. The airflow control system (100) includes an airflow housing (120) defining an airflow passageway (125) extending between a bypass opening (122) and an intake outlet (124). The airflow housing also defines a duct opening (126) positioned between the bypass opening (122) and the intake outlet (124). The intake outlet (124) may be in fluid communication with an engine intake (12) of the vehicle such that air passes from the bypass opening (122) and/or the duct opening (126) to the engine intake (12). The airflow control system (100) also includes a movable duct (160) movably connected to the airflow housing (120) to selectively allow or prevent air passage through the duct opening (126) and into the engine intake (12), and further includes a bypass door (140) movably connected to the airflow housing (120) to selectively allow or prevent air passage through the bypass opening (122) and into the engine intake (12).

An air intake system for an aircraft engine includes an air duct having an inlet port to provide fluid communication between the inlet port and the engine and a removable air filter assembly configured to interface with the inlet port of the air duct and a skin of the aircraft. The air filter assembly includes an air filter frame having an outer wall and an inner wall, the outer wall of the air filter frame forming an air filter slot. The air filter assembly also includes a bypass door forward of the air filter slot and an air filter insertable into the air filter slot. The bypass door is movable between a closed door position and an open door position, air flowing to the inlet port of the air duct via the air filter in the closed door position and bypassing the air filter in the open door position.

A vehicle provided with an engine, at least one air intake through which the engine takes in the external air needed to operate, and an air filter, which is arranged in the area of the air intake; the air filter comprises: at least one wave-shaped filtering material panel; an outer reinforcement mesh, an inner reinforcement mesh; and a heating device which is electrically connected to a group of electrified wires of the outer reinforcement mesh and is designed to cause an electric current to flow through said electrified wires, so as to generate heat, due to the Joule effect, on the inside of said outer reinforcement mesh.

A control method for controlling an air intake system for an engine of a vehicle; the intake system has a main air intake coupled to an air filter provided with a heating device. The control method comprises the steps of: determining a pressure difference between upstream and downstream of the air filter; determining a variation speed of the pressure difference between upstream and downstream of the air filter by calculating the first derivative in time of the pressure difference between upstream and downstream of the air filter; and turning on and/or turning off the heating device based on the variation speed of the pressure difference between upstream and downstream of the air filter.

An aircraft includes a fuselage, an engine exhaust port extending through the fuselage, an air intake extending through the fuselage forward from, and adjacent to, the engine exhaust port, and an air cleaning assembly positioned over the air intake. The aircraft also includes a pressure recovery device including an outer wall positioned above the air cleaning assembly. A distance from a forward edge of the outer wall to the air cleaning assembly is greater than a distance from an aft edge of the outer wall to the air cleaning assembly. An inlet flow axis is defined normal to a cross-sectional flow area of the pressure recovery device at the forward edge, and is oriented upward at an acute angle relative to a longitudinal axis of the aircraft.

A cover for an intake of an air-breathing engine in a missile is disclosed. The cover comprises a motive arrangement operable to move from a first configuration in which the cover is lockable to a missile, to a second configuration in which the cover is pushed outwardly from the missile. In the first configuration, the surface of the cover is flush with the surface of the missile and the motive arrangement is located inwardly of the cover surface. A missile provided with such a cover is also disclosed.

A modular jet trainer aircraft which can be reconfigured to provide a plurality of different handling aircraft particularly beneficial in the training of pilots. A base structure on which elements can be changed to alter the handling capabilities, maneuverability and power of the aircraft. The aircraft may have a first basic configuration which enables a pilot to learn relatively basic handling skills. The propulsions system and/or wing structures can then be changed to provide an aircraft with more sophisticated handling and greater power capabilities. The engine is located fully outside the fuselage structure whilst still being positioned on the centre-line of the fuselage and with the engine's line of thrust directed through the centre of the fuselage and close to the aircraft's centre of gravity. By achieving this, the expensive design of the fuselage as primary or airworthy-critical structure can be completed independently from the installation of the engine.
