Собираем автожир

Honey Bee

Примечание переводчика: отчеты Ральфа по этапам сборки находятся в процессе перевода. Там, где перевод закончен, вы увидите, соответственно, перевод. Если этап не перведен, он обозначен (на этой странице) по-английски: Phase # и вы попадаете по такой ссылке на соответствующую страницу на сервере самого Ральфа. Ваш Mr.Twistair

В начале марта Don Chubb и я получили кит Honey Bee. Нашей главной задачей было успеть   подготовить автожир к приближающемуся летному сезону, но одновременно появилась возможность оформить различные стадии сборки в виде отчетов, показывающих, насколько хорошо стыкуются элементы кита и какова трудоемкость сборки этого аппарата. В процессе сборки мы, конечно, столкнемся с некоторыми сложностями, но я собираюсь описать здесь и то, как мы с этими сложностями справлялись. Они выделены в тексте красным шрифтом - для того, чтобы вы не повторяли наших ошибок.

Предполагая, что сборка пойдет без особых затруднений, мы планируем вскоре оценить и летные характеристики, используя мой комплексный прибор Digipod, чтобы позже поместить здесь соответствующий отчет.

Что ты получишь в ките

Кит Honey Bee приходит в восьми ящиках, плюс детали хвостового оперения, упакованные отдельно. На фотографии они не показаны, т.к. были распакованы раньше, чтобы нанести на них регистрационные знаки (A10RET). Каждый ящик имеет свое обозначение, что имеет свой смысл и становится понятным, когда раскрываешь руководство по сборке.Сборка разделена на несколько этапов, и детали для каждого этапа упакованы в отдельный ящик. Все металлические детали аккуратно упакованы и отлично окрашены порошковой краской. Поскольку нам хотелось соблюсти пчелиные традиции, наш кит имеет стандартную желто-черную схему окраски.

The manual itself is organized according to the construction phases with each phase documented by detailed prints. What makes this kit outstanding is that the hardware required is inventoried and bagged by sub-steps within each phase. For example, in the first phase you assemble the main elements of the airframe - the keel, tail boom, and mast. As just one example, the nose wheel block attaches to the front of the keel using a pair of cheek plates and lots of hardware. The cheek plates are individually-packaged in heat-sealed plastic and all the hardware for their installation is packaged in its own bag, complete with an inventory label! This makes it impossible to use the wrong hardware and shortages at any stage would be very obvious!

All the components are precision (CNC) drilled and machined. Since the are powder-coated after machining, you do need to clean the paint from the holes with either a 3/16 or 1/4 inch drill bit, but there is no actual drilling in the conventional sense. Our feeling was that the kit should go together very quickly, but we'd find out!

NOTE:

While the CADD prints in the manual are excellent, the manual did not have any narrative text or descriptions to assist in assembly. This led to places in the construction sequence where we ran into problems that we either solved on our own or in consultation with Jim or Bob at GyroTech. These mini-problems led me to the idea of expanding this site to provide more notes on details where problems might arise. Now that the factory has most of their production issues solved, I am sure they will add to the manual. In the meantime, consider this an on-line supplement!

Because each building session is typically documented with both pictures and a fair amount of text, this page quickly grew to the point where loading took a LONG time. I have now put most sessions on their own page via the links you will see below. There are a few exceptions, in cases where the sessions did not involve a lot of descriptive material. Below the last active link you can see the total construction time up to that point in the project.

Phase 1 - Детали рамы

Phase 2 - Носовое колесо

Этап 3

This was a VERY short session after Bensen Days as Don was on-call and got called! We did complete the nose-gear unit. A small wedge was used to open up the strut holes on the horizontal braces and we got everything assembled without scratching any paint! The side bracket problem resolved itself when we realized that the cut-out sides of each horizontal bracket face forward!

Total session time: 0.5 hour Total time: 4.5 hours

Phase 4 - Шасси

Phase 5 - Установка основного шасси

Phase 6 - Finishing the Frame

Этап 8 - Моторама

If we were precisely following the instructions, the next stage would involve mounting the control stick (Phase 6). However, we have made up our minds to try an overhead stick, so we spent a good bit of this session talking about how to do that! Meanwhile, off to Phase 7 - engine and fuel tank mounts.

The engine mounts are VERY rugged (1/4 inch stock) and the fit to the holes in the mast and the diagonal seat braces is perfect! You have two sets of mounting holes that can be used to accommodate props of different lengths. We used the upper set of mounting holes to keep the thrust-line as low as possible. The diagonal engine struts also fit just fine, but we called a halt when we had some unresolved questions about the use of spacers where the lower end of the struts connect to the mast.

Total session time: 2.25 hours Total time: 16.25 hours

Phase 9 - Топливный  бак

Phase 10 - Установка хвостовой группы

Phase 11 - Установка двигателя

Phase 12 - Сборка топливной системы

Phase 13 - Установка втулки ротора

Phase 14 - A Different Overhead Stick

Phase 15 - Rudder Cable Modifications

Phase 16 - Изменения в хвостовом колесе

Phase 17 - Instrument Pod

Phase 18 - Twist-grip Throttle

Phase 19 - Wiring

 

Общее время сборки: 35.75 часов

Well, that's it - the machine is done! Well will certainly spend at least another hour or more tweaking and fine-tuning things, but it is obvious that, despite all the custom modifications we made, there is no reason that a Honey Bee cannot be built in 40 hours or less.

ЛЕТНЫЕ ИСПЫТАНИЯ

OK, it's done so we go out and fly it, right? Hardly! It is a brand new aircraft, straight off the shop floor and there is a lot to be checked out. Although the design is proven, we have also made some significant modifications, such as the trike-style control bar, that require a step-by-step check-out. We obviously know how to fly the Gyrobee, but we won't assume we can fly this gyro without completing three essential phases of flight testing:

    1. Initial check-out and ground handling
    2. Blade spin-up and crow-hops
    3. Initial pattern flights

We will describe each of these phases in enough detail to help you with your own flight-test program. Remember, you should not go past step 1 until you have been signed off for solo. Even then, you should spend more time in each phase than we did, for the simple reason that you still have a lot to learn!

Flight Test Phase 1: Initial Check-out and Ground Handling

Flight Test Phase 2: Blade Spin-up and Crow-hops

Flight Test Phase 3: ** DISASTER **

Strictly speaking, the links that follow are not construction phases but do represent essential information for anyone building a Honey Bee or Gyrobee. Now that we are based at a regular airport (with lots of fixed-wing ultralight pilots), I am amazed at the problems encountered by many pilots in terms of engine wiring and instruments. The problem is, most kit manufacturers don't include the essential information required, leaving the builder to stumble around if they don't happen to be familiar with the subject. These links are intended to help builders who are not really sure how to proceed.
