Helicopter engineering

Seth Young (Johnston Heights)
Hey everyone, So i have been doing a lot of designing and just trying to get ideas on paper and this is what i have discovered so far. First the cheapest way for me to get propellers with engines is to buy the ones that are made for hang gliders and those sorts of things. They are less expensive then making it some other way and are normally powerful enough for me to get all the lift i require. However i did encounter a problem with this in the fact that they are all fixed pitch rotors. this...Read More...

Hey ya'll i am back and that is right, I am actually gonna try to build this flying machine this year. Will i crash and burn? Probably. Will i get get injured? Almost certainly. Do i care? Not as much as i should. In all reality tho this is easily going to be the most difficult undertaking i will have ever made, for a variety of reasons. First off it is very very very veeeerrry dangerous. Secondly all of the little portions and control mechanisms are more important than they seem. Thirdly...Read More...

New Ideas

Seth Young (Johnston Heights)
Hey there everyone, we are back from summer and it looks like its time to get started once again. This year is a year of stress and fun for a lot of us so lets all do our best, eh? So i have a few ideas for my projects this year, the main three i am looking at is to continue the bionic boots build and actually make them this year so i would be starting that soon. If not i am thinking about doing more on the helicopter project (If i can get funding i would loooooove to build it) or buying an...Read More...

Hey Everyone!! This cycle i will be working on Ocean Health as i had a talk in my Social Studies class that piqued my interest. There main things i plan on focusing on are Ocean Acidification, Coral Bleaching and Algae Blooms. I want too work with these as i feel they are all interconnected and i should be able too learn some new things in the sciences and in the humanities with them. I plan on starting with ocean acidification first, then moving on. I think that i may have a final project...Read More...

C4 RR3: Algae Blooms

Seth Young (Johnston Heights)
Todays research is on Algae Blooms, enjoy What are they? Its actually pretty obvious, an algae bloom is where a large amount of algae grows in a certain area, normally quite rapidly. These tiny organisms form dense patches near the surface creating colours on the surface of the water, hence the name, "Red Tides". These harmful algae blooms, also known as HABs, are very very dangerous. the can produce toxins that kill animals and infect shellfish (These are often the cause of Paralytic...Read More...

C4 RR2: Coral Bleaching

Seth Young (Johnston Heights)
So todays research round is on coral bleaching. What is it? Coral Bleaching is an environmental phenomena that is happening in oceans all over the world, from islands in the Indian ocean, to Hawaii and even the Great Barrier reef. Coral gets it's vibrant colours from the symbiotic algae living inside it. This algae produces glucose, amino acids and carbon, all necessary for coral too live and grow. However when corals become stressed they expel this algae out of them, leaving them an off...Read More...

Hey everyone it turns out i had accidently not posted my finished posts, and so i will have a big rush of them coming today. Ocean acidification, What is it? What is Ocean acidification? In all honesty it is relatively easy to explain. It is the changing ph levels in our oceans or the rising acidity of them. However things get a little more complicated in the how and why it exists. Why does it Happen? There are plenty of reasons for this phenomenon, however one of the main ones in the...Read More...

C3 RR6 Plaster.....

Seth Young (Johnston Heights)
Hey everybody!!! It was great seeing and talking too everyone today, hope we have more chances too do that sort of thing. Now on to the research. I have really been doing a lot of talking with my friend trying too figure out what i will need for him too be able too help me with this, as he is far more experienced and well versed in working with plastic with i am. So basically i need too make a plaster cast of my leg and foot, then make a mold of the inside of that so that we can build a...Read More...

Hey Everyone! I know I know, im getting bad at posting, sorry about that. But i have been doing some research and i have realized some things. The basic things starting are that i need to one make a leg mold for my leg, so that i can get melted plastic around my leg shape. I need to make a leg cast since i don't want molten plastic on my leg. The second is that i need to layer plastics to create both strength and flexibility. This has something to do with the rigidness of most plastics, so...Read More...

C3 RR:4 First Designs

Seth Young (Johnston Heights)
Hey everyone! I'm back with some designs. So i have been working on these for a little bit, sadly my art skills are still lacking. This means i have to explain more or less what is going on in these photos. Fist off they look a lot like like these bionic boots: These are as far as i know the best bionic boots on the market, therefore the perfect place to find inspiration. However there are some very key differences. The first is that my foot pad extends far beyond the toe. This is to attempt...Read More...

Hey everyone! Today i am continuing with ostriches and using them to create my running shoes, speed boots, or whatever i am going to call them. I looked today at the bottom of the ostrich, the point where every other piece actually matters, the impact point. Today i look at the feet. First point of the feet is to clarify something. Due to an ostriches interesting skeletal structure, the only part that actually touches the ground are their toes. The rest of their foot is what seems to be the...Read More...

Hey everyone, sorry i have not been posting i have been away, so i haven't really been able to. I have however been doing some research while away so i am starting to understand how this may all work out This round i looked into the bio-mechanics behind how ostriches run. I did this to help me figure out the best way to design a boot off of their legs. First things first, Ostriches don't actually have backwards facing knees. That's actually their ankle joint. Ostriches have the same amount...Read More...

Hey there everyone, this is another post on ostrich physiology and how i plan on using it in my projects. This post is about the muscles , tendons and bone structure. Its basically explaining how the ostrich moves its legs, and therefore its body. First off lets look at the bone structure of an ostrich. Ostriches have the longest legs, compared to the size of its body of any ground bird. this gives it the largest stride length as well, one of approximately 5 meters when running. That's a...Read More...

The Exoskeleton is done, and this is going to be my second to last post on that topic. I will have one more video of me in the exoskeleton and it actually working. But after looking back on this project i have learned a lot. I have learned a lot about how things work, and most importantly more about myself. This will hopefully give you, a small chance to experience what happened in this journey of mine. In the first part of this adventure i faced almost an immediate problem, and that was...Read More...

Hey there everyone! So this is going to be my last helicopter post. This is because i have learned almost everything i can about helicopters. I have learned how they create lift, how they steer and some of the troubles about building them. I have also learned about historical helicopters, the first designs, the first models and some of the coolest ones around right now. Although i would love to build one, and i plan on making one at some point in the future i have realized that it would cost...Read More...

C2 RR6 Exo Update

Seth Young (Johnston Heights)
Hey everyone. So today is just another Exoskeleton update, However this time i started connecting the exoskeleton to myself, so i can now wear it. Its super heavy, probably in the range of 45 lbs or so, so i had to add cushioning on parts. So that is what it looks like now. I used tie ons for moving that have 1000lb breaking strain so it will definitely hold the weight. Thanks for reading! SethRead More...

Hey everyone, i have gone back to some of histories helicopters, and i have found that the first helicopter designed (that we know off) was designed by Leonardo Da Vinci himself. Leonardo was an incredibly talented inventor and spokesperson. He came up with some of the first plans for submarines, helicopters, and even scuba gear. The two i am looking into are the flying screw and the flying machine, both reminiscent of today's planes and helicopters. The first one is called an orthnocopter...Read More...

Hey everyone, I'm back with another quick update on the exoskeleton. Since I am in the midst of building it i have realized a couple complications with in the project. One is that i drastically underestimated the price of some of the things i wanted to buy. (My online research showed 15 dollars or so each, real life dictates it is 10 times that). That means that i had to make some adjustments to the legs, taking a large piece out and changing up some of the ways the joints will face. This...Read More...

Hey everyone Merry Christmas, Happy Holidays and Happy New Year. I have not posted in a while, but that doesn't mean i have not been working on my projects. I found that i had been doing a lot, so i would just send in some videos instead of writing. I apologize for the bad sound and video, as i am no computer guru. Here it is: https://www.youtube.com/watch?...bjr_kx9o&edit=vd Thanks for watching, and reading. As always your questions comments and concerns are greatly appreciated. SethRead More...

Helicopter Engineering #8

Seth Young (Johnston Heights)
Hey everyone. So this week i looked into early helicopters and what they were made of, and the helicopters of today and how they are made. I did this just to see how far helicopters have progressed, and to see what materials are going to be the most likely in making up my project. The first thing i looked into was the old helicopters, and their materials. Its interesting because the idea for helicopters has been around for hundreds of years. The first helicopter, flying machine design, was...Read More...

Exoskeleton #8

Seth Young (Johnston Heights)
Hey everyone. So this week i was supposed to start buying my materials, mainly on the weekend. I plan on building from the feet up, and i realized that for my boots i can use a pair of hiking boots i had lying around the house, this meant that i needed to start getting the perforated steel tubing and the steel rods. Unfortunately the bank wanted to keep holding the check so i will not be able to start the purchasing of materials until this weekend coming up. Other than that I looked into...Read More...

Hey everyone, This week I did a little bit of research on mechanical advantage for the design of the exoskeleton arms. Mechanical advantage is the effectiveness of a machine, normally shown in a ratio like 1:4. This means more or less that if you have a mechanical advantage of 1:4 that if you put in an amount of effort the result is going to be roughly 4 times that. This means you can do more with less effort, or in my case lift more with less power. Now this is relatively basic mathematics,...Read More...

Hey everyone, So as I posted previously i am looking into safety and legality of this build. So far i have been mainly focusing on the legality because i feel that it is important for me to figure out whether or not i can get fined or not for building it. So far the legality of actually building one seems pretty simple. I am allowed to build it with no permits or anything of the sort, as long as I do not use it for commercial purposes. As I will be the only person on this ( Also for safety...Read More...
Hey everyone, So I am back, and was researching safety precautions that i could use if the need arose, however i realized i had a problem. I still do not know whether it is legal for me to fly a homemade helicopter, and if there are certain restrictions or guidelines for flying them. I researched on the ministry of transportation website, however they only had information on ultralight airplanes and amateur airplanes. I could not find any information on the legality of flying an amateur, and...Read More...
