Definitions
- the invention relates to a method for the targeted depositing or picking up of goods from aircraft according to the preamble of claim 1. It is known to load or unload goods or people from aircraft. This creates the problem that landing must be done for this purpose.
- Patent specification FR 2364 851 A from April 1978 describes a device which allows the load to be deposited via a cable truss spanned in the room.
- the problem here is the need for the aircraft to be permanently pretensioned for the cable truss.
- the permissible radius of movement of the aircraft is limited by the geometry of the cable truss and the requirement that all cables must remain pre-tensioned.
- the generation of the vertical preload by the aircraft is associated with considerable energy and design effort.
- Patent application P 19625297.0 dated June 1996 describes a method which shows and solves essential aspects which are not mentioned in the above-mentioned patent. Basically, however, the problem of pre-tensioning a spatial cable truss by the aircraft remains.
- the utility model DE 295 09 940 (November 1995) also represents a device for draining goods or people, which tensions safety ropes to the floor for better fixing of the people. A clean spatial fixation and the geometric conditions required for this are not discussed.
- the invention is therefore based on the object of specifying a device and a method by means of which a targeted setting down to the point-precise setting down or picking up of a load is made possible, even if the ambient conditions do not allow the aircraft to be held steady and a vertical preload up to Soil is not possible or undesirable for any reason or cannot be ensured during the duration of the procedure.
- the position of the intermediate platform is already largely fixed in space, without requiring that the aircraft is at rest. Inaccuracies in the position of the intermediate platform can occur during the lowering of the intermediate platform and before being fixed by the pressure supports.
- the aircraft itself is at a sensible distance above the load. The preload between the aircraft and the intermediate platform is obtained from the lift of the aircraft, which is to be kept largely constant during the landing process.
- the load is released from the intermediate platform via a cable system which permits a further increase in the positioning accuracy.
- a cable system which permits a further increase in the positioning accuracy.
- This can be, for example, vertical ropes that allow the load to be moved manually, even with large masses to be moved, or a system that is in turn connected to the ground, which enables the load to be guided to the drop point (such as guide rails, docking devices, etc. .).
- damping elements can be, for example, spring elements, hydraulic dampers or the like.
- each individual pressure support in itself also represents a damping element.
- pressure-absorbing elements can only gradually absorb increasing pressure forces after connection to the floor and rough adjustment of the intermediate platform in order to keep the impact load on the overall system low.
- This can be achieved, for example, by means of kinematic chains or mechanisms that are limited step by step in degrees of freedom on several joints that are to be chosen sensibly and thus lead to an increasing stiffening of the space structure.
- Another variant here is the use of a support to be stabilized by internal pressure, which is only stiffened by applying internal pressure and thus builds up the space structure.
- the space structure can also make sense to construct the space structure from a composite of pressure-absorbing supports and tensioning elements (e.g. ropes) that serve to fix these pressure supports.
- the structure of this support network should take into account the special requirements from the individual steps of the entire process, provided that this appears to be given and useful. This can represent, for example, a movable mounting of the pressure supports, which is only able to absorb compressive forces after the connection to the floor via the tension element bracing.
- the decoupling of the possible movements of the aircraft from the intermediate platform about the vertical axis is achieved by suitable devices which can be integrated both in the system between the aircraft and the intermediate platform, in the aircraft or in the intermediate platform.
- suitable devices which can be integrated both in the system between the aircraft and the intermediate platform, in the aircraft or in the intermediate platform.
- this can be sufficient twistability of ropes or a slewing ring.
- step 1 the aircraft is still cruising to the destination.
- step 2 the aircraft sinks to the target flight altitude, which is selected according to the local conditions and requirements.
- step 3 if necessary, the load space is opened and the load is lowered. Alternatively, the load is generally below the aircraft, so there is no need to lower it specifically. Then this step is omitted.
- step 4 the aircraft is placed at the target flight altitude and now only has to compensate for the wind and lift changes. But it does not have to be at rest, but in constant motion.
- Steps 5-8 are shown in Fig.2.
- step 5 the space structure is prepared to absorb compressive forces, if necessary. Alternatively, the structure is always in the extended state.
- step 6 the connection to the floor is made. This is one of the process steps in which spring damper elements may play a helpful role.
- step 7 the frame is clamped, if necessary, and is able to absorb compressive forces at the latest from this point in time.
- step 8 all preparations for lowering the load from the intermediate platform are completed.
- Steps 9-12 are summarized in FIG. 3.
- step 9 the load is released. Further fine adjustment is possible if the appropriate facilities are installed.
- step 10 the weight of the dropped load is neutralized by balancing ballast, if necessary.
- This balancing ballast can be taken in a variety of forms.
- Steps 11-16 are shown in Fig.4.
- step 11 the connection to the ground is released after the necessary dissolution of the pressure force association has been carried out.
- step 13 if structurally provided, the supporting structure for storing the intermediate platform is retracted.
- step 14 the frame and the ballast, if provided, are retracted.
- step 15 the transition to cruise is initiated.
- step 16 the aircraft is again in the cruise.
- the aircraft can also be a balloon or a helicopter or any other aircraft that does not require horizontal movement in order to generate lift.
- the frame shown for hanging the load can be dispensed with if the problem makes sense
