简介:Tailless Delta&Stndrd。配置。机械铅笔滑翔机

关于:飞机爱好者和梦想飞行员。

Welcome! To make these gliders, you’ll need fine motor skills, attention to detail, and patience. If you're new to making flying things, the guidance of someone who knows about aircraft and flight will come in handy, especially when it comes to testing and trimming the gliders.

如果您是教师并计划为类项目使用这些项目,您可能希望让学生成对或小组工作。请注意,Tailess Delta明显更易于构建。为了有趣和一些额外的学习,我建议距离竞争,一个控制竞争(如在一定距离的环上飞过戒指),或者两者的组合。

Here are some possible prompts for builders to answer.

CALCULATIONS

  • What is the mass of each glider?
  • What is the wing span of each? (Once the glider is constructed, measure a straight line from tip to tip.)
  • 每个翼面积是多少?(与翼跨度一样,您应该指的是一个塑料形式。)
  • Using the mass and wing area, calculate the wing loading of each glider.

COMPARISON

  • 哪种设计似乎有更多的偏航稳定性?什么可能陈述这一点?
  • Which seems to have more roll stability? What might account for this?
  • Which seems to have a better glide slope?
  • 如果你是飞行员,这些都是满量程飞机,你宁愿飞吗?解释。

创建

  • What modification do you plan to implement, and on which glider? What do you hope the modification will do for the glider?
  • 如果设计一个完全新的东西,你的脑海中最重要的是什么?

Supplies

  1. Sheets of 8.5" x 11" card stock; 65 lb. or 180 gsm
  2. 塑料机械铅笔与主管上的夹子;15厘米长(下面有更多信息)
  3. 铅笔尖橡皮擦
  4. 剪刀
  5. 胶棒
  6. Metal ruler and hobby knife (not entirely necessary, but helpful)
  7. Clear adhesive tape; 2 cm wide

Step 1: Prepare Pencil

找到一个机械铅笔,最好是有一个破碎的弹簧或只是磨损。它应测量15厘米长,具有六边形,由透光塑料制成,并具有邻接主管的袋夹。Officax和BIC是我使用的两个品牌,我更喜欢BIC,因为它似乎是一个触感打火机。

Remove the eraser and graphite. Take out the rod, which will probably require removing the tip of the pencil and making a cut to free a small rubber stopper. Remove the spring, and put the cap back on. Cover the other end with a pencil eraser.

Step 2: Delta—Print Plans & Cut Out Shapes

Print the plans onto a sheet of card stock. Use 65 lb. card stock, or 180 gsm if you live where metric measurements prevail. Gluing two sheets of lighter material together, such as some decent quality 90 gsm paper, could work (and thank youCodeMind.)。

仔细切断形状。如果您计划使用业余爱好刀,请确保它非常尖锐。在使用业余爱好刀之前,较年轻的建筑商应该从成人获得许可。

第3步:胶水和折痕

Before using your glue stick, double check that you're working on the correct side of the card stock piece. Applying a thin and consistent layer of glue, and attach the brace piece to the top of the main wing. Use a straightedge to start creases on all of the dotted lines. Start with the center line. In so doing, you will make the wing dihedral. The wingtips should rest about 5 degrees above horizontal.

将内部升高约5度。只需几度即可升高苗条的外部。仔细检查左侧和右侧的对称性。

Step 4: Finish Wing

将机翼提示的角度增加至90度,从而定义垂直稳定器/小翼。现在,使用拇指和指尖轻轻夹紧前沿捏,略微卷曲卡片库存。重复几次,逐步工作,直到卡片股票保持形状。

Before sliding the wing into place, check that the notch at the forward point of the wing is wide enough. Depending on the brand of pencil you're using, the clip may be too wide and you'll need to widen the notch.

第5步:将翼拧到铅笔

获得一条测量8厘米的磁带,中间制作参考标记。找到机身底部(铅笔)的点,从机翼前面7厘米。将胶带的条带塞在那个点并坚持下去。小心地将胶带粘附在机身的侧面,然后将胶带粘附在机翼的底部。避免在这样做的同时在翅膀上拉下来。

第6步:标准配置。 - 打印,切出形状,并造成折痕

正如您将迅速注意到,这款标准配置滑翔机(即在后端的尾部)更复杂。期望花40到60分钟工作。

仔细切断形状,然后在虚线上开始折痕。电梯(在水平稳定器的后缘)应升高约10度。目前,翼形和翼支架的中心线的折痕可能非常温和。

第7步:机身和鳍工作

将长窄的机身条带胶水到主体顶部。有参考线以确保良好的放置。接下来,将较短的条带胶水,长度为8.5厘米,到机身的底部。该一个应该在稳定器的后缘之前延伸到机翼区域约5mm,结束1cm。

将最短和最窄的条带粘在水平稳定器的底部。它穿过先前附着的条带,并与它的末端齐平。

Bend the tabs at the bottom of the two vertical stabilizer pieces to 90-degree angles. Apply glue to one of the vertical stabilizers, but not to the tab area. Unite it with the other half. After the glue has set for a couple minutes, apply glue to the tabs and attach the stabilizer to the tail of the glider. Use the reference lines.

第8步:翼工作

Glue the wing brace to the top of the wing and let the glue set for a minute. Re-establish the crease on the center line. The wing tips should be about 7 degrees above horizontal.

将胶水涂抹在翼根。仔细连接机翼。确保它垂直于机身。

切成中心附近的四条短黑线。现在通过反复沿着领先和尾部边缘夹紧翅膀略微底部的翅膀。慢慢地去检查左边,往往是对称的。参考曲线在计划中。

第9步:将主件固定到铅笔

将机翼滑入铅笔上。获得一条测量7厘米的胶带带。找到机身底部的点,从机翼的前缘返回5毫米,并标记它。将磁带带,并根据您使用Delta滑翔机完成的粘附。最后,获得2.5厘米的磁带,并将其连接到机身顶部,在垂直稳定器前面的几毫米。将胶带夹在侧面。当你这样做时,请小心保持尾巴与机身完美级别。

第10步:测试航班和修剪

Trimmingrefers to small adjustments of an aircraft's control surfaces and/or weight distribution in order to achieve a desired flight path.

如果可能,在室内进行测试飞行和修剪。轻轻地扔滑翔机和水平。它们不太可能是尾部沉重的,但如果是,你会注意到它很快。尾部重型飞机驾驶和拖过空气,往往迅速猛烈地崩溃。如果您的滑翔机飞行相当稳定的航班,但是比您更快地下降,增加了千分之一或电梯的偏转。您还可以通过将橡皮擦进一步推到铅笔上或通过将橡皮擦转换为二手橡皮擦来进行重心返回重心的实验。

左侧或右侧的趋势最可能是不对称翅膀的结果。定期检查翅膀,并尝试纠正任何不一致性。如果标准配置滑翔机轻轻转到右侧或左侧,只需轻微滚动,即可通过舵址解决。通过三角洲,您应该能够对外部升级进行调整趋势。您也可以将稳定器的尾部边缘翘曲少量,如微小的舵手。为了简洁起见,我没有完全解释如何调整舵手和升级。也许您可以通过在飞行基础上签出书籍来支持您的本地库。

Lastly, don't forget to have fun! I hope they fly well for you. If they don't, keep in mind that everyone who ever made a glider has gone through the same frustration you're feeling. Keep at it, and you will get better!

Step 11: Video [optional]

If you are a student, do not watch this! No, seriously, you shouldn't. Preserve your objectivity for testing and comparison of the two gliders.

    This is awesome! Perfect next step for me and the kids to take after paper airplanes. I had a flight obsessed period as a kid, going through wing designs and measuring flights, and this brought it all back! These pencil gliders will give us hours of fun and endless opportunities for learning - THANK YOU.
