Abstract

The utility model relates to a suspended drag craft which is composed of a boat body, a vertical tail, a carrying cabin, a traction rope and a tension wire. The utility model is characterized in that the traction rope which is connected with an external traction tool of a boat is arranged on the suspended drag craft without a propelling device, and a plurality of tension wires which are connected with both are symmetrically arranged between the vertical tail without a rudder and a horizontal tail without an elevator. The utility model is respectively connected with traction tools which move in the air, on a water surface and on a land to form a delivery system of an air to air, a water to air and a land to air drag boats. Because the utility model has the requirements of security and economy, and traction mode and a tool are flexible and various, market prospect is optimistically viewed.

Description

Suspended drag craft

The utility model relates to a kind of dirigible, particularly a kind of no propelling unit itself and the floating empty dirigible of outer power traction, abbreviation Suspended drag craft.

Dirigible is a kind of aircraft that is lighter than air, fills hydrogen (fire gases) dirigible and some once occur and play fiery accident, and is not too safe.Fill helium (unreactable gas) though dirigible safety, cost too high (helium is than expensive about 200 times of hydrogen), load coefficient relatively little (proportion of helium is 2 times of hydrogen), the delivery cost of unit commercial transport is than higher.Like this, be subjected to very big restriction with regard to the application that makes dirigible.Its basic reason is that common dirigible integrates propelling and two kinds of functions of load-carrying, is difficult to solve the contradiction of safety and cost.For this reason, the applicant once advised on (seeing 1999 3 phases of " transport plane engineering " magazine) above-mentioned two kinds of Function Decomposition to two kind of different dirigible with dirigible, and one for being equipped with the traction dirigible of propelling unit, and one is the carrying dirigible of no propelling unit Suspended drag craft one by one, then, make the two series connection flight.The traction dirigible has driving engine, for safety, should fill helium; Because of it does not bear the commercial transport task, so its volume can reduce greatly, deadweight can alleviate greatly.The carrying dirigible is because of the thermal source of no driving engine generation, can fill proportion than helium low 50% and price is about its 0.5% helium.Like this, just can under the condition that guarantees safety, reduce the manufacturing and the operating cost of total system, thereby the contradiction that this long-term restriction dirigible of the safety of making and cost is used is solved preferably.As a kind of Suspended drag craft of bearing the commercial transport instrument merely, not only can draw by the dirigible or the helicopter of airflight, but also can be by the ship of surface navigation, the automobile of land locomotion, trac. and tank wait and draw.Small-sized Suspended drag craft is under the condition of calm or little wind, and also available animal (as camel, ox, horse even people) draw.The variation of mode of traction and drafting tool will enlarge the field of application of Suspended drag craft.It not only can be used for the general communications and transportation in area, many river valleys, many mountains, also can be used for military project national defence, geological mapping, development of the field, desert afforestation, scattered seeds by airplane for afforestation, the marine shoal of fish, aerophotography, air rescue, exploitation and the large-scale celebration aspect such as make a show of power of searching.Use it for and go sightseeing to travel, then can satisfy the go up to the sky hope of a trip of more people.

The purpose of this utility model provides a kind of Suspended drag craft, drag ship to be connected with the drafting tool of land motion with aerial, the water surface respectively this, can form absolutely empty, water is empty and the empty three kinds of new means of conveyance in land, thereby select transportation means that the more freedom degree is provided according to condition and needs for people.

The purpose of this utility model is achieved in that it is made up of ship body, vertical tail, tailplane, carrying cabin, trailing cable and bracing cable, it is characterized in that: on the Suspended drag craft of no propelling unit, the trailing cable that is connected and transmits its tractive force with the outer drafting tool of ship is set, between the tailplane of the vertical tail of directionless rudder and no elevating rudder, left and right symmetrically is provided with some the bracing cables that connect the two.

The utility model has the advantages that:

1, the thermal source that produces because of no propelling unit even fill hydrogen, also unlikelyly produces explosion accident on fire as the common hydrogen airship that fills, thereby is quite safe;

2, owing to can fill hydrogen, thus its make and maintenance cost lower;

3, the load coefficient is bigger;

4, mode of traction is flexible, and drafting tool is various, thereby is convenient to use and promote.

Below in conjunction with accompanying drawing the utility model is described further.

Fig. 1 is a formation scheme drawing of the present utility model.

Fig. 2 is the right elevation of Fig. 1.

By Fig. 1-2 as can be known, the utility model is made of tailplane (3), carrying cabin (4), trailing cable (5) and the bracing cable (6) of the vertical tail (2) of ship body (1), directionless rudder, no elevating rudder.The ship body is for inflation usefulness, and vertical tail is for strengthening lateral stability usefulness, and tailplane is for strengthening fore-and-aft stability usefulness, and trailing cable is used for the outer power traction of ship; Bracing cable then is used to strengthen the integral rigidity (this ship of the horizontal expression of the trailing cable of accompanying drawing is by the traction of aerotow instrument) of empennage.

Claims

1, a kind of Suspended drag craft of outer power traction, it is made up of ship body, vertical tail, tailplane, carrying cabin, trailing cable and bracing cable, it is characterized in that: on the Suspended drag craft of no propelling unit, the trailing cable that is connected and transmits its tractive force with the outer drafting tool of ship is set.

2, according to the described Suspended drag craft of claim 1, it is characterized in that: between the tailplane of the vertical tail of directionless rudder and no elevating rudder, left and right symmetrically is provided with some the bracing cables that connect the two.
