Abstract:
The invention relates to a vacuum toilet system for transporting toilet waste water and for collecting the waste water in an aircraft. The vacuum toilet system comprises a waste water transport tank and a waste water collection tank that is always subjected to a cabin pressure. In this case, the vacuum toilet system is designed in such a way that the transport of the waste water through the waste water transport tank takes place in combination with a pressure difference between the toilet and an outboard ventilation. The waste water is collected in a waste water collection tank. In this case, the waste water collection tank may be realized in the form of a conform, unpressurized waste water collection tank.
Abstract:
A cylinder head of an internal combustion engine includes at least one exhaust port, which is formed by a port liner of at least two layers cast into the cylinder head, provided with a heat-insulating layer and having a sheet metal port, the sheet metal port being surrounded by a helically wound sheet metal strip.
Abstract:
A fuel cell system for an aircraft is stated, which fuel cell system comprises a fuel cell unit and a suction module. The suction module is used to draw oxygen through the fuel cell unit. No vacuum generators are used during cruising flight.
Abstract:
In a cylinder head of an internal combustion engine having an exhaust passage, a lower cylinder head part, an upper cylinder head part, and a bolt-on surface on the exhaust side with an exhaust manifold bolted thereto, a sealing surface is arranged in a recess extending along the exhaust passage into the cylinder head and the manifold has a tube which extends into the recess in sealing engagement with the sealing surface at the bottom of the recess and which is spaced from the surrounding wall of the cylinder head recess, through which the manifold tube extends in a curved fashion.
Abstract:
In a cylinder-block for an internal combustion engine with a plurality of cylinders having longitudinal profiled sections in the form of lateral hollow reinforcement structures and vertical sections in the form of profiled reinforcement structures, in the region of a main bearing plane means are provided for supporting a lateral camshaft beneath the upper longitudinal profiled section, and, in the region of the bearing structure for the camshaft the vertical profiled section is divided in two.
Abstract:
A device for locating artillery and sniper fire with a sensor and acoustically triggered marking means. An igniter is provided with the acoustic sensor and is adjustable in terms of frequency and/or pulse pattern. A remover preventer is provided and the components are provided in a shell-proof housing whereby removal triggers the marking means.
Abstract:
Submunition is transported by a carrier to a target area and launched there, whereupon it covers a preset distance at a constant altitude at an angle to the flight axis of the carrier. The submunition has a target sensor and a payload, and is equipped with an altimeter as well as a circuit to evaluate the altimeter readings, and with at least one altitude/roll rudder controllable by this circuit.
Abstract:
An injection module for a subammunition container, of the type in which subammunitions, ejected transversely to the flight direction of the subammunition container, are situated in front of driving devices which are actuated by gas-generator-driven ejecting pistons. The ejecting pistons are arranged transversely with respect to the flight direction, and may extend along half the width or the full width of the ejecting module. The gas generator may be arranged transversely or longitudinally of the flight direction.
Abstract:
In an arrangement for handling the fuel in a common rail fuel injection system of an internal combustion engine, wherein fuel is supplied from a tank via a fuel delivery line including a first fuel filter, a low-pressure pump arranged upstream from the first fuel filter and a high pressure pump arranged downstream of the first fuel filter to a high pressure fuel rail from which the fuel is distributed to the cylinder of the engine, a bypass line extends from the high pressure fuel rail to the fuel delivery line and includes a second fuel filter and a heat exchanger which is operatively connected to a cooling circuit of an air conditioning system or to a cooling circuit of the internal combustion engine.
Abstract:
A load glider has, between the parachute surface and the load, a device in which a reversible transfer of mechanical energy from the main lines to the steering lines takes place, so that essentially only frictional forces are to be overcome during the operation of the steering lines. The device includes two differential gears, which are arranged in parallel and are accommodated in housings in which a steering line is wound up on a roller with a larger diameter and a main line is wound up on the other roller with a small diameter. Gears, which can be driven by pinions driven by electric motors, are flanged onto the larger rollers.
