滑翔伞伞绳检查

分享到:

贴一篇关于伞绳检查的文章从UP官方偶得了一份关于检查伞绳的文档,感觉很实用,介绍给大家。其中方法主要适用于UP的滑翔伞,但相信对于别的品牌,基本原理是完全一样的,也可作为参考。因为要从英文一点点翻译过来,所以更新的速度会较慢。

Trim control and service information for UP serial pruduction paragliders

 

也许每一个飞行员都有这种感觉,飞了一段时间之后,伞头开始变得有一点不一样了,伞头进入气流的时候不像以前那么干脆,起伞的时候伞也表现的有点沉,甚至感觉速度也有了一些变化。所有这一切的原因都十分简单:我们的滑翔伞是用织物做成的,所有的织物都不可能是100%稳定不变形的。这篇文档就是让飞行员们有一个简单的方法和流程来检查自己的伞,以保证自己的滑翔伞始终处于一个最好的状态。

Any pilot who has flown for some time knows the feeling; after some time the new wing

starts feeling just a little bit different. The canopy doesn’t pull into the thermals as

before, the inflation is just that little bit more sluggish, and maybe the speed feels a tad

less impressive than it used to do. The reasons for these signs of aging are simple:

Paragliders are made from textiles, and textiles are not 100% dimensionally stable.

Sure, ongoing development has improved the situation greatly in recent years but

sensitive pilots will still be able to sense a difference over time.

With this information folder UP International wishes to bring forth a new paraglider pilot

attitude towards issues like glider checks and line control. Just as a motorist checks oil

levels and tire pressure, and the bicyclist checks the brakes and the connections, the

paraglider pilot has a few simple tools up his sleeve to ensure that the wing is always in

top condition.

The following paragraphs should introduce these tools to the pilot and hopefully make

them into an integrated part of the standard „toolbox“ for pilots. With them, the checks

become 2. nature and no more complicated than checking the oil levels on the car.

Our goal is to enable pilots to orientate themselves on the wings‘ overall condition by

performing a few simple steps. Done regularly, these checks will serve to increase both

safety and performance of any paraglider.

 

第一步,简单伞绳检查

The ” Easy trim check”

 

所有的UP滑翔伞的最接近组带的伞绳组,例如A1、B1、C1、D1组,A2、B2、C2组,同组的长度都是完全相同的。所以可以很简单的检查,如果滑翔伞每组伞绳长度相同,一切OK,如果伞绳长度不一,则进入下一个检查程序

 

这个检查结果就是完美的。

 

All UP wings are designed so that the

lower lines are of identical length in the

chord direction. A1, B1, C1 and D1 are

identical, as are A2, B2, C2 etc. This

makes it easy to check the glider trim.

Fixate the risers onto something heavy,

walk to the end of the lower lines and grab

hold of first the A1, B1, C1 and D1.

Compare the lengths. If anything, the A’s

and B’s may be somewhat longer and the

D’s somewhat shorter than the C’s.

Continue with the A2, B2, C2 and D2‘s,

then the A3, B3, C3 and D3’s..

 

第二步,进一步伞绳检查 The simple trim check

 

从09年4月起,UP的滑翔伞开始在伞绳离伞15公分左右的地方留一个小记号,这种记号在伞上有三组,分布在三列伞绳上。当伞是新的时候,每组伞绳从组带到记号处的长度都是相同的。(但多数滑翔伞飞了一段时间,AB组都会变长或者CD都会变短,不信你回家量量试试)

 

 

As of April 2009, UP gliders are

manufactured with a small marker on

three of the upper lines on each side,

approximately 15cms below the bottom

surface of the canopy. When the glider is

new, all these markers are equidistant

from the riser maillons, and they allow the

pilot a very simple means of checking if

the glider is still in trim. Each wing half has

3 markers per line level, always situated

on the inside forking, see drawing here on

the right.

Simply fixate the risers to a single point,

walk to the canopy and compare the lines

chordwise, i.e. A1, B1, C1 and, if

applicable, D1. On gliders that have

already been in use for some time the

likely outcome of this easy check is that

the A’s and B’s are a bit longer than the

C’s and D’s.

第三步,用户自我调整The “Home User Check”(HUC)

 

滑翔伞是会变形的,伞绳是滑翔伞的基础部分,同时也是最容易变形的部分,以下文档介绍了如果伞绳发生变形后最简单让伞暂时恢复的方法,但是这种方法不能代替定期返厂检测维护。

As has been touched upon in the material

description texts, paragliders may begin to

change as soon as they leave the factory.

The lines are the structural part of the

wing that may change the most over time.

This document is intended as a brief

description of the correct way to bring the

lines back to within their tolerances in

case this should be needed.

 

重新拉伸伞绳

Re-stretching the lines:

1,把组带固定在一个稳定的地方,刹车把手也要绑死。如果没有合适的地方,找个胖子坐在坐袋上也是个不错的主意。

1. Fixate the risers to a solid point. The

brake handles toggles should be

attached together with the risers, as

we will need to pull on the brake lines

as well. If no solid fixture is available,

a heavy person could sit in the

harness while the HUC is performed.

2,抓住A组的两根伞绳,一只手一根,用力往后拉三下。注意,每一次都是用一只手一根伞绳这种方式,同时处理两根伞绳。然后顺着一个方向在同一组中一根一根往后换。这样每一根伞绳都会被拉六次。A组拉完之后,同样处理B、C、D。

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

2. Grab hold of two A-lines, one in each
repeat 3 times. IMPORTANT!hand. Apply a firm pull on the lines,

Always grab two lines at a time, or

the gallery lines could break

(unsheathed comp lines only).

Move ONE line sideways and

repeat, so that each gallery line is

stretched 6 times. Repeat for BC-

D- E- brakelines.

 

注意,要是这样拉可就完蛋了!!

 

 

NEVER pull on just

one line, or pull on the sail –

you could damage your

wing!

 

多大力量合适?

在工厂里,使用的力量是20公斤。自己拉的时候,确实要凭感觉(英文原意我找不准,请高手帮帮忙)How firm is a firm pull

When pulling on the line you will feel a

distinct stretching sensation. When the

stretching is replaced by a more „dead“

sensation the line has reached its optimal

length, and no further force should be

applied.

In the factory the lines are subjected to a

20kgs pull.

 

那些型号的UP滑翔伞需要这样做?

所有用Dyneema伞绳的滑翔伞都需要时不时的拉一拉。具体如下清单

Trango2 (except the Race

Version)

Trango3

Summit3

Kantega2

Rock2

Edge

Summit XC* (only 2008)

Pico* (only 2008)

Ascent

Ascent2

K2

Which glider models dose this apply to?

All gliders with a complete Dyneema line

configuration are subjected to line

shrinkage. At UP this means the following

models should be re-stretched

occasionally

 

 

以下型号由于不是完全的Dynmma伞绳,所以不需要这种处理

For the following UP gliders, along with

older models, it’s not necessary to

stretch the lines as they have Aramid

lines or a mixture of Aramid and

Dyneema. Note that we still

recommend occasionally subjecting

the wings to the „Easy trim check“, the

„erformance check“ or simply

sending the wing to UP or a UP

approved checking facility for a twoyears

check:

Kantega

Kantega XC

Summit XC* (from 2009)

Pico* (from 2009)

Trango2 Race Version

Makalu, Makalu2

Kuna, Pulse,

Sherpa, Sherpa2

Rock
