DE3144051A1 - Vacuum lift missile - Google Patents

Abstract

The vacuum lift missile is similar to earlier airships. However, its internal space is evacuated rather than being filled with a light gas. To this end, the stabilising frame is also constructed for reversed operation (external pressure instead of internal pressure). Because of the lift principle, this missile has a greater lift than the light-gas balloon and can be used in all fields of aviation, military reconnaissance, atmospheric research, and as a lifting device, scaffold, children's toy and in other fields. The advantages over other flying machines are the good vertical manoeuvrability, which is ensured by carrying the vacuum pump on board, the small cost outlay for propulsion and production, and finally the good environmental friendliness.

Description

1. Description

1.1. Areas of application The invention has the following possible applications: As a military aircraft for reconnaissance and strategic purposes, as good radar camouflage and noise-free flying is possible, as an observation aircraft for the police, traffic watch, Meteorologists, geophysicists, oceanologists, ecologists, etc., as rescue and recovery aircraft For mountain rescue, sea rescue, fire brigade, etc., as a load lifter and transporter for the replacement of cranes, helicopters and elevators for objects that are difficult to access, as a floating assembly platform at building sites, as a carrier for scientific Probes in the high atmosphere, as children's toys, as advertising aircraft, for Renaissance of the classic airship for luxury and leisure travel, as well as Replacement for all on the principle of buoyancy by light gases (hydrogen, helium9 Hot air) previously built balloons and airships.

1 2. Purpose The purpose is to invent a new principle of buoyancy for aircraft which has the following advantages over previous designs offers: Reduction of material and energy consumption, lowering of manufacturing and operating and maintenance costs more environmentally friendly operation, quieter operation, expansion of aviation in the military sector and renaissance of classic airships for travel and Amusement industry.

Description and claims 1.3. State of the art The flying machines used so far are based on the aerodynamic lift principle and on the aerokinetic light gas lift principle. The aerodynamic principle bird flight is used in modern aircraft and the light gas principle is known from the time of the tethered balloons and the Zeppelin airships is currently still used for advertising purposes in the toy industry and for highly atmospheric Measuring probes used. The ones for vertical take-off and landing as well as for flying with so-called helicopters used at low speed are based on the aerodynamic principle.

1.4. Criticism of the state of the further or. Reuse of the light gas principle the following disadvantages stand in the way today: The filling gases are too expensive (helium) or too dangerous (hydrogen), the missiles require too large dimensions and Elaborate aids are required for take-off and landing and vertical maneuvering which in turn limit this maneuverability.

Because of this and because of the greater cruising speed, the in aviation only uses the aerodynamic principle.

Nevertheless, the aerokinetic principle has the opposite of the aerodynamic one Principle a number of advantages that are particularly important in today's time of the oil crisis and the growing environmental impact are critical. these are among other things the environmental friendliness'the lower noise pollution and the lower Energy expenditure, since no lift energy is required during the flight phase.

Description and claims 1.5. Task The The task is to provide a reuse for the aerokinetic Principle to be found under point 1.4. excludes mentioned disadvantages. the Solution is only possible if you can do without filling gas and still have the buoyancy enlarged.

1.6. Solution According to Archimedes, buoyancy is equal to weight the amount of substance surrounding the body displaced by the body this principle is applied as an aerokinetic principle in aviation in that you filled a missile (balloon or airship) with a gas which was easier than the ambient air was. The same effect can be observed after that of Archimedes also achieve the found law with an evacuated container. This container must similar to gas balloons made of a specifically light material and this The material must be stable against an external pressure of 760 Torr and relatively vacuum-tight be.

These materials are available today in the polymer plastics'in the light metal alloys and the plastic-coated light metal alloys. In addition, the static knowledge gained in lightweight construction technology can be used apply here. The following is offered as a possible solution: The external pressure is absorbed by a framework made of pipes. These consist of glass fiber reinforced plastic or light metal. Pipes are because of the cheap Suggested resistance moment in connection with the lower weight. To obtain In order to ensure that it is vacuum-tight, the missile is given an outer skin made of plastic light metal or plastic-coated light metal. Construction must be description and claims between the required lift; the size of the missile and the mass of the material be optimized.

With an optimal construction and from a certain size onwards Due to the omission of the filling gas own weight, a greater buoyancy than with the light gas principle can be achieved.

Landing, take-off and vertical maneuvers, which are better than the light gas principle is achieved by the fact that the missile is equipped with a bus inlet valve (landing, falling) and a vacuum pump (buoyancy, starting) is equipped.

1.7. Achievable advantages compared to aviation no longer applied light gas principle there are the following advantages that a reintroduction enable: smaller dimensions, better maneuverability, flawless Take-off and landing without aids, reaching greater heights, greater carrying capacity, less Expenditure of material and resources, harmlessness compared to the earlier dangerous ones Filling gases (hydrogen) lower material, operating and maintenance costs, elimination more complicated landing sites and independence from thermal changes in the atmosphere.

Compared to the aerodynamic principle of today's aircraft and Helicopters have the following advantages: Low energy consumption due to elimination the continuous consumption of buoyancy energy, environmental friendliness and low noise levels certain material use and certain flight altitude good radar camouflage in the military Area, greater safety because buoyancy is independent of the drive, greater load capacity, speedless gliding without energy consumption and with great safety, elimination of runways, lower operation and maintenance description and costs Claims and the better use as a load lifter and floating assembly platform.

1.8. Expansion possibilities The vacuum-lift missile can also deal with aircraft and helicopters based on the aerodynamic principle combine.
