The airship consists of a structure, an energy power part, a navigation control part, a communicating part, and the like. The utility model is mainly characterized in that light-weight and high-intensity keels are arranged along the center shaft of the airship; both ends of the keel are respectively and fixedly connected with a cephalic cone and a tail cone; the upper part of the middle of the keel is connected with a bearing inhaul cable arranged on inner curtain cloth of an inflatable bag; the lower part of the middle of the keel is fixedly connected with a suspending cabin; both sides are fixedly connected with a supporting mechanism of lifting wings; and thereby, the inner frame of the airship is formed. Compared with the traditional semirigid airship, the utility model has the characteristics of simple structure, low cost and high loading capacity; compared with the traditional taut airship, the utility model has the characteristics of high flying speed, high wind resisting capacity, long flying time, good maneuverability and good controllability; and the utility model can build an air service platform to be used in the army and civilian fields of reconnaissance pre-warning, electronic countermeasure, communication retransmission, television broadcast, environmental monitoring and the like.

Description

Rise floating one blimp

Technical field

The utility model relates to the floating one blimp of a kind of liter, belongs to aerostatics branch in the aircraft field.

Background technology

Dirigible can be divided into soft, semihard formula and rigid three classes by its constructional feature.The tradition blimp carries with static lift, and load capacity, flying speed, flight time, wind loading rating are limited, take off and the road-holding property that lands relatively poor.This blimp has increased the rigidity keel in utricule inside, can reduce the air bag internal stress, is with a pair of dynamic lift wing to produce lift, can promote dirigible and carry ability, flying speed and flight time.The traditional semihard formula, the rigid airship that carry ability relatively equally can reduce cost again significantly.

Summary of the invention

The purpose of this utility model is to provide a kind of cheap blimp that not only utilizes lift but also utilize buoyancy, possesses good airworthiness and landing maneuvering performance.This is the floating one blimp of a kind of liter, it is characterized in that having rigidity keel that run through the hull center shaft, and the awl end to end of these keel and dirigible is formed semihard formula structure, and ship body both sides have a pair of rotatable dynamic lift wing.

Main technical schemes of the present utility model is: dirigible partly is made up of structure division (air bag, keel, gondola, the dynamic lift wing, empennage and alighting gear etc.), energy source and power (driving engine, screw propeller, fuel oil system and electric power system etc.), navigation control system and communication system etc.Dirigible dependence air bag arranges the static lift of air generation and the lift wing of dirigible and the dynamic lift that ship produces and comes balance dirigible and load weight when flight; Power propulsion system provides the thrust of flight forward, and vectored thrust provides taking off of the auxiliary dirigible of normal thrust component and lands; The flight attitude and the direction of yaw rudder and elevating rudder control dirigible.

Form profiles such as similar spindle or water droplet behind the dirigible airbag aeration, along the hull center shaft light-high-strength keel are set in the air bag the inside, the keel two ends connect firmly with nose cone, tail cone respectively, keel middle parts is gone up with carrying drag-line on the cord in the air bag and is linked to each other, following and gondola connects firmly, both sides and lift wing supporting mechanism connect firmly, and form the semihard formula inner frame of dirigible.

Before and after the dirigible air bag inside air bag is set respectively, is used to adjust the gas intracapsular pressure of dirigible, play the booster action of regulating center of gravity simultaneously.

The nose cone of dirigible head setting mainly is that dirigible improves deflection arch portion rigidity when facining the wind, improves the dirigible wind loading rating, realizes the ground mooring simultaneously.

On the lift wing supporting mechanism that dirigible middle part and keel connect firmly the lift wing is installed, the dynamic lift underwing is installed the dirigible driving engine, and 30 ° verted about the dynamic lift wing and driving engine can carry out under the control of control system.Under the state of verting, the thrust component of vertical direction also is provided except that the power that provides forward driving engine, strengthens the stress efficacy of the lift wing, and auxiliary dirigible takes off and lands.

The dirigible afterbody is provided with empennage, plays the effect of stablizing airship flight, can control the flight attitude and the direction of dirigible by the rudder face of regulating empennage.

The navigation control system of dirigible, communication system, energy resource system are installed in gondola inside.

Compare traditional dirigible, the utility model has following advantage:

(1) adopt built-in gondola design, drag coefficient is littler than traditional dirigible;

(2) can under bigger net weight power, take off also and can descend to, be fit to long period flight in big net buoyancy;

(3) have stronger lift-launch ability and cheap cost.

The specific embodiment

Below in conjunction with accompanying drawing and flying height is that the specific embodiment of 3km is described further the utility model, but not as to qualification of the present utility model.

As shown in Figure 1, balloonet 4 and back balloonet 7 constitute before being provided with in the dirigible air bag, charge into helium on ground in air bag, account for 70% of whole air bag cumulative volume, and balloonet 4,7 charges into air, accounts for 30% of air bag cumulative volume; When dirigible flew to the about 3km of height above sea level height, the surplus airs in the balloonet 4,7 accounted for 6% of ship capsule cumulative volume.When low-latitude flying, also can adjust the dirigible center of gravity by the gas filed ratio of balloonet before and after adjusting.

As shown in Figure 2, running take off/landing modes is adopted in taking off/landing of dirigible: when taking off, main gasbag buoyancy is main lift, dirigible slides the takeoff speed that reaches certain at the ground runway, regulate the dynamic lift wing 10 to the rising corner, make driving engine and screw propeller 9 produce normal thrust component upwards simultaneously, under the combined action of buoyancy, engine thrust and dynamic lift wing lift, go up to the air; The net weight landing time only need reduce flying speed, suitably regulates dynamic lift wing angle and engine throttle according to the sinking speed of dirigible, and line up with runway just can slowly land; The net buoyancy landing then need keep minimum flying speed, regulate the dynamic lift wing 10 to the decline corner, make driving engine and screw propeller 9 produce downward normal thrust component simultaneously, under the combined action of engine thrust and dynamic lift wing pressure, slide landing, the flight attitude of dirigible is by empennage 12 controls, realize yaw attitude control by deflection vertical tail rudder face, realize pitch attitude control by deflection level empennage rudder face.

Claims

A kind of liter floats the one blimp, it is characterized in that having rigidity keel that run through the hull center shaft, and the awl end to end of these keel and dirigible is formed semihard formula structure, and ship body both sides have a pair of rotatable dynamic lift wing.
