Abstract

A changeover module to turn ultra-light flying vehicles into road- going vehicles has glass-fibre sides (1,3) fastened to the tubular frame. There is a protective ring (5,6) surrounding the propeller. The brake system on the wheels using mechanical or hydraulic disc or drum brakes is boosted. The lighting systems on the nose and the sides are integrated. A tiller or joystick (7) for road travel is joined by a hinge to a thrust rod for the nose wheel fork. An ECU with a sensor (11) monitors the speed on the road. A special propeller with smaller diameter is used for road travel. It can be exchanged with the flying propeller. There is stowage room (10) for the necessary safety equipment.

Description

1. Application 1.1 General

The invention can be used to convert existing aircraft of the ultralight / trike type (in the following UL or ULs or trikes) to the fully compatible road vehicle according to the StVZO (Road Traffic Licensing Regulations) can be used.

1.2 State of the art / tested publications

Various registrations even from before the Second World War point to the Desires of the operators of aircraft, also on the ground the aircraft for the to make ground-based air traffic usable. There are several of them Applications (patent specification 760 791, 333884, 1016568).

Common to all, however, is the specialization in a specific component (333884) or another drivetrain. Only recently with the advent of the Ultralight aircraft have been various options for ground propulsion technology for ULs registered (e.g. DE 34 30 412). No comparable technique could be used for the research be determined according to the registration.

1.3 problems

The trike-type ultralight aircraft that are common in aviation have a load-bearing structure Elements over different pipe constructions which give the device the necessary Giving stability (framework function). Many UL operators are forced to fly their aircraft not to be kept at the landing site because the capacities in the halls are exhausted. Around However, to accommodate the ULs, many operators have to laboriously open and close their ULs dismantle and accommodate in private shelter. The respective journey to Landing site and the assembly and dismantling, as well as the subsequent loading on car trailers means for many operators a considerable amount of time, physical effort and financial type.

1.4 solution

The inventor hereby presents an unprecedented solution which the Conversion to road vehicle has the content. In this respect, execution and idea is new. With this invention, expensive renting of hall spaces and driving is avoided to the landing site can be done by means of the aircraft. Also are ground based Trips in the wider area of the target landing area possible, as well as the ground return to the starting point in bad weather.

2. Description

The invention relates to an arrangement according to the preamble of claim 3.ff. The arrangement according to Fig. 1 (drawing 95033101 consists of the following components / elements and is structured as follows:

2.1 Structure: Name of the individual components / elements

Pos .: 1 GRP outer shell on the right
Item: 2 fasteners for item 1
Pos .: 3 GRP outer shell on the left
Item: 4 fasteners for item 3
Pos .: 5 propeller protection on the right
Pos .: 6 propeller protection on the left
Pos .: 7 handlebar
Pos .: 8 brakes
Pos .: 9 lighting devices
Pos .: 10 room for safety accessories
Pos .: 11 transmitter with electronics
Pos .: 12 road propellers

2.2 Structure: Description of the structure

A conventional UL of the trike type is converted into a fully-functional road vehicle by means of the invention. The GRP shells ( 1, 3 ) are fastened to the frame construction of the trike using fastening elements ( 2 , 4 ). As an additional benefit, the aircraft also has a much better aerodynamic shape. The propeller is protected from dangerous contact by a wire cage as propeller protection ( 5 , 6 ) (only in road operation). A handlebar ( 7 ) is connected to the nose wheel fork by a pull and push rod, it is used to control the UL in road operation. The handlebar ( 7 ) is folded away during flight operation. The brake system ( 8 ) is expanded to operate the rear wheels, disc or drum brakes ensure increased braking of the UL. Lighting devices ( 9 ) on the front and rear of the vehicle make it roadworthy even in poor visibility, in addition, these can be combined with the usual lighting in aviation, which increases the degree of use. A storage space ( 10 ) for the accommodation of the prescribed emergency equipment (first aid kit, warning triangle etc.) completes the conversion module. Control electronics ( 12 ) with a transducer attached to the nose wheel monitor compliance with the permissible maximum speed in road operation. For road operations, the flight propeller is exchanged for a smaller propeller for road operations by means of a quick release hub and secured against contact by means of the propeller protection ( 5 , 6 ). The wing is removed and stored or dismantled for road operation.

2.3 Procedure: Description of the conversion

Conversion is carried out by an appropriate specialist workshop and must be carried out by the TÜV be removed (explanation required).

Claims (1)

Conversion module according to pos. 1 to 11 of Fig. 1 (drawing 95033101) for converting existing ULs of the type trike to a fully road vehicle according to StVZO, characterized in that side parts ( 1 , 3 ) molded from GRP or another suitable plastic by means of fastening elements ( 2 , 4 ) are attached to the tube construction of the trike. A propeller guard ( 5 , 6 ) covers the propeller in such a way that the moving parts of the propeller are covered. The braking system on the rear wheels ( 8 ) is reinforced by means of disc or drum brakes (mechanical or hydraulic). The lighting devices ( 9 ) on the bow and in the side parts can be integrated. A handlebar ( 7 ) for operation as a road vehicle is connected to the nose wheel fork by means of a pull and push rod. Control electronics with sensors ( 11 ) monitor the speed limit in road operation. A special propeller ( 12 ) with a smaller diameter takes over the drive of the UL in road operation and is replaced by means of a quick release hub. A storage space ( 10 ) for the safety means required in road traffic and propeller protection ( 5 , 6 ) is integrated in the outer shells ( 1 , 3 ). The propeller protection ( 5 , 6 ) can be dismantled.
