Abstract
The utility model discloses a blimp power arm. The power arm comprises a support frame, a fixed circular ring and a ducted shaft, wherein the fixed circular ring is fixedly arranged on the support frame; the ducted shaft is arranged on the fixed circular ring by a bearing; an engine is arranged on the ducted shaft; a propeller is arranged on the engine; and both the support frame and the fixed circular ring are formed by connecting aluminium tubes and connection joints. The blimp power arm disclosed by the utility model has the characteristics of light weight, high intensity and good processing manufacturability. Moreover, the design scheme adopted by the utility model can be used in design of other system structures (such as a nose cone and a tail cone) connected with an airship gasbag body, and has expandability.
Description
Technical field
The utility model belongs to aerostatics structure design field, is specifically related to a kind of blimp power arm structure.
Background technology
Power propulsion system is the heart of dirigible, is one of subsystem of dirigible most critical, reaches flight function, posture changing and other operation function requirements of dirigible by power propulsion system.Good and bad maneuvering performance and the aerial mission that directly affects dirigible of power propulsion system performance completed quality.Power arm is the platform that provides support for the airscrew engine in the dirigible power propulsion system and fuel oil control unit, the parts of most critical in power propulsion system, power arm together with engine unit etc. provide dirigible upwards, downwards, to wait the thrust of all directions, the quality of power arm design directly affects the function realization of power propulsion system forward fine or not.
Prior art is due to the dirigible profile, and power propulsion system adopts abdomen to put formula more, is about to propulsion system and is connected on the gondola that belly hangs.The form that adopts the both sides power arm is also arranged on Large Airship, large-sized power arm configuration form also due to the driving engine characteristics and installation form varied, type of attachment adopts Type of Welding to be connected on the skeleton of rigid (or partly rigid) dirigible more, as Germany " Zeppelin " NT series dirigible.
The advantage that adopts the Type of Welding power arm is to connect simply, and is easy to operate, but welding after vibration performance is difficult to assurance, the stability shortcoming.For obtaining High Performance dirigible power propulsion system, assurance is arranged on the smooth operation of the screw propeller of power arm, and power arm is had very high intensity, rigidity requirement; Guarantee that power arm good suspension behavior on dirigible reaches the burden requirement requirement to airship envelope, has had again corresponding weight requirement to power arm.Because power arm has lightweight and the high double requirements of intensity, there is the technical barrier in the rational structure design of power arm.
The utility model content
The utility model is intended to overcome the deficiencies in the prior art, puts the near characteristics of formula power advance distance centre distance with respect to abdomen, and a kind of blimp power arm is provided.
In order to achieve the above object, the technical scheme that provides of the utility model is:
A kind of blimp power arm is characterized in that described power arm comprises bracing frame, is fixed in the clamping rings on bracing frame, is installed on duct axle on clamping rings by bearing; Described duct axle is provided with driving engine, and driving engine is provided with screw propeller; Support frame as described above and clamping rings are formed by connecting by aluminum pipe and jointing.
Wherein, pass through rivet between described aluminum pipe and jointing; Described power arm mirror image is installed on the left and right sides of dirigible.
Below in conjunction with principle of design, the utility model is described further:
In power arm of the present utility model, bracing frame is used for supporting clamping rings, the shape of bracing frame and dirigible balloon shapes coupling; Clamping rings mainly plays fixedly propeller system, for smooth operation, the starting characteristic of screw propeller provides good running environment; Clamping rings adopts the bearing type of attachment with being connected of duct axle, has guaranteed two degree of freedom operations of screw propeller.The power arm mirror-image arrangement is in the arranged on left and right sides of dirigible.
In addition, in the utility model, the keystone configuration of bracing frame and clamping rings all adopts for the distinctive tubular type connection structure of blimp structure form, namely, the mode that adopts aluminum pipe to be connected with adaptor union, aluminum pipe are pressed the moulding of required connection shape under certain bending curvature, designed adaptor union form can be the multidirectional jointings such as two-way, three-dimensional, four-way, flexible structure, this type of attachment have guaranteed continuity and the conformability of total.
Compared with prior art, the beneficial effects of the utility model are:
In the utility model, the mode that power arm design utilizes aluminum pipe to be connected with adaptor union has alleviated the weight of whole system, has also guaranteed simultaneously the Rigidity and strength of each parts.Owing to adopting adaptor union to connect aluminum pipe technique, saved mould, make processing technology simple, and cost.This connection mode has been passed through corresponding test examination, and intensity meets designing requirement.This structure has reliable, lightweight, the smooth characteristics without wearing and tearing of contact surface that connect.By the design of this kind structure, continuity and conformability good and the matching utricule structure and total have been guaranteed.
The utility model power arm mirror-image arrangement is in the arranged on left and right sides of dirigible.The promotion program that adopts both sides to advance, propelling unit is also far away apart from the distance of center of gravity, and larger yawing moment can be provided, and can realize that by the speed discrepancy that changes screw propeller dirigible tilts or driftage is controlled simultaneously.
In a word, the utility model is in conjunction with blimp, designs to be suitable for the power arm installed on this dirigible, reasonably selects power arm version, connection mode and rotation mode etc., accomplish lightweight, intensity is high, fabrication properties good.In addition, design plan of the present utility model can be used for having extensibility in the design of other system architectures that are connected with the dirigible utricule (as nose cone, tail bone).
