Abstract
The utility model relates to a helicopter flotation pontoon lobe system. Current helicopter flotation pontoon lobe is mainly forming with the metal part equipment, and there have the processing degree of difficulty to be big, big, the with high costs and interchangeability subalternation problem of weight. Design that a processing is simple, light in weight, with low costs, accord with the structural feature of the anxious system of floating and the helicopter flotation pontoon lobe device that has interchangeability, satisfy the requirement of the emergent system of floating of helicopter.
Description
Technical field
This utility model belongs to helicopter and meets an urgent need floating system, more particularly to a kind of helicopter floating drum separation system
System.
Background technology
Helicopter floating drum separation is that helicopter is met an urgent need the capital equipment used in floating system, and its function is just
Floating drum air bag is installed in face, and gas bottle device is installed at the back side, by floating drum air bag and gas cylinder integrated management, and as passing
Pass the main member of float buoyancy.Existing helicopter floating drum separation is mainly assembling with metallic element,
There is difficulty of processing big, the problems such as weight is big, cost is high and interchangeability is poor.
Summary of the invention
Install and use scheme in conjunction with what helicopter met an urgent need floating system, design a kind of processing simple, lightweight,
Low cost, meet the construction features of anxious floating system and there is the helicopter floating drum separation device of interchangeability, full
Foot helicopter is met an urgent need the requirement of floating system.
Floating drum separation installs additional based on the task of emergent floating system by certain type helicopter, meets an urgent need in conjunction with helicopter
Floating system and the handling characteristics of floating drum separation, comprehensive analysis formulation floating drum separation scheme, final design forms.
Helicopter floating drum separation, is made up of nacelle and air bottle fixing bracket, and nacelle uses the middle temperature of carbon fibre composite
Solidification is fabricated by, and air bottle fixing bracket uses stainless steel belt riveting to form, and nacelle and air bottle fixing bracket use
Straight pin is hinged and is spirally connected the connected mode combined；Nacelle passes through installing hole and the helicopter body of its surrounding
Install, there is in the outside of nacelle floating drum air bag assembling fork ear and coordinate with floating drum, having in the inner side of nacelle
Accommodate the mounting bracket of gas cylinder and coordinate with air bottle fixing bracket.One end of air bottle fixing bracket is provided with regulation bolt
It is used for the fastening force regulating air bottle fixing bracket with gas cylinder.
This helicopter floating drum separation has simple, lightweight, the low cost of processing and has the features such as interchangeability.
The development of this equipment makes the installation of the emergent floating system of certain type helicopter and application effect improve a lot,
Using effect is good.
Accompanying drawing explanation
Fig. 1 is the floating drum separation of this utility model helicopter；
Fig. 2 is the scheme of installation of this utility model helicopter floating drum separation.
