Nathan Denmead wins National science fair
with his experimental rocketry
 black powder rocket engine project

 

 

 

I first came into contact with Nathan when he emailed me on March 31, 2008.  He had accessed my 1979 free manual on black powder rocket motors and had a question about the derivation of an equation in it.  That led to several emails back and forth where I was able to enjoy following his project while answering a question here and there when I could.  I am quite proud to know this young man even though it is only through email, and quite proud of his accomplishments.  This page is a tribute to all the work Nathan has done which resulted in winning multiple levels of New Zealand's science fairs.  See the text of Press releases of his wins further down this page.

 

 

Background

Hi, I’m Nathan Denmead. I am currently 16 and in my last year of high school at Waimea College in New Zealand. I first discovered rocketry, when he found a sack of potassium nitrate in his father shed, found some recipes on the net, and what followed was a whole heap of smoke, big bangs, flying skyrockets and mathematical formula. First starting on rcandy with tin foil as casings, soon progressed to black powder propellant rocket motors.

The opportunity to do a science project first arose in year 12 physics. Where students were require to carry out a major practical as part of the curriculum. To showcase my progress in rocketry I decided to do my project on rocket motors. After weeks of consultation from Gary Jacobs I finally chose to investigate the relationship between the specific impulse the propellant density of rocketry motors. In other words I wanted to see how much compressing the black powder affected the rocket motors performance. Gary Jacobs played a leading role in helping me understand the complex principles and formula. From this project came so many opportunities and the media releases show the extent of this.

What now

I am currently looking a completing a degree in Mechanical Engineering, but nothing has really been confirmed. These opportunities and experiences have really helped broaden my horizon of what paths I could take, and expanded my knowledge. I am really grateful for all these amazing experiences that have been given to me, and I urge you to take all opportunities take you are given, they are just out there waiting for you.

NZ student did have to be a rocket scientist

RICHMOND, Nelson NZ — If Waimea College student Nathan Denmead decides on a career in science, he's launching it the right way, by picking up four top science fair awards for his project Rockets Away.

The 16-year-old on Thursday won the overall National Institute of Water and Atmospheric Research Senior Science and Technology Fair Award for his project, which explored developing a suitable rocket motor to be used in model rockets.

He investigated how the density of a propellant affects the rocket motor's performance. conclusion, he said, was complicated, but the higher density gave better performance.

His work also earned him three more of the top six awards - the John Cross Award for Best Investigative Research, the Otago University Hands-On Week for Best Investigational Method Award, and the Ernest Rutherford Best Physics Investigation Award.

He also won a Standard Science Gold Award and the Australasian Institute of Mining and Metallurgy Award.

"I'm very happy," Nathan said. "I didn't think I'd win that many awards."

The year 12 student is considering studying science at university when he finishes secondary school.

Of the top six awards handed out, the Overall Niwa Junior Science and Technology Fair Award went to Nayland College student Caitlin Attenburrow for her project Colour Thought, while Garin College student Nic Barkley was awarded the Ernest Rutherford Best Technology Project award for Sparkle Jam.

The Nelson Regional Science and Technology Fair was open to all primary and secondary schools in the Nelson region.

The projects were judged and displayed last month at the Ernest Rutherford Retirement Village, where Thursday night's prizegiving was also held.

Realising his Dream

Last week local student, Nathan Denmead along with twenty-eight other students from around the nation was selected to have a blast of a time up in Wellington. The prestigious Genesis Energy Realise the Dream event was held to celebrate excellence in research. The local model rocket enthusiast was selected to go for his research on model rocket motor performance.

Over the week the students were taken around Wellington, visiting the cities iconic attractions. This included tours of the national Isotope Centre, Karori Wildlife Sanctuary and the Weta museum. “We were even treated to a cocktail evening hosted by UNESCO at the Boat House, which was a great success. My highlight for the week though was the day at Massey University, where we built our own light seeking robotic car and a Sterling engine which could generate electricity” said Nathan.

He also said that going to Realise the Dream was a really amazing experience. Meeting like-minded people at this once-in-a-lifetime opportunity really got him exited about what science has to offer. “I would really encourage people to get involved, it’s not about being a geek, it’s about doing something you’re passionate about.”

On Thursday night a farewell BBQ was held to rap the occasion up. A number a travel awards were announced and Nathan was extremely surprised to find himself winning the Asia New Zealand Foundation Travel Award to the Beijing Youth Science Creation Competition taking place over March. “I could hardly believe it” Nathan said as he expresses his awe.

Later next year, in March, the celebratory awards dinner will be held at Te Marae, Te Papa where cash prizes of up to $7,000 and international travel to London will be presented. Genesis Energy Realise the Dream is also sponsored by DairyNZ and The New Zealand Commission for UNESCO as well as other organisations that support individual awards.

Nelson student's rockets take him all the way to China

WAKEFIELD, Tasman NZ — Making homemade gun powder to fire rockets with may seem like a dangerous pastime for some, but mixing the explosive powder himself gives Nathan Denmead's rockets a speedy edge.

The year 12 Waimea College student conducts his experiments in a little shed at his Wakefield home, and his diligent research has paid off, as he has been awarded an Asia New Zealand Foundation Travel Award to the Beijing Youth Science Creation Competition in March.

The 16-year-old rocket enthusiast and four other New Zealand students were awarded the all-expenses-paid scholarships when they attended the recent Genesis Energy Realise the Dream event, which celebrates excellence in students' research.

Nathan was picked to attend the event for his research on model rocket motor performance, which won him the overall National Institute of Water and Atmospheric Research Senior Science and Technology Fair Award, a Nelson-wide competition open to all primary and secondary schools.

Nathan's rockets, made of sturdy cardboard, can fire about 80 metres into the air and have engines packed with layers of clay and gun powder - made from Nathan's homemade mix of charcoal, sulphur and potassium nitrate.

Nathan picked up his interest in rockets from his older brother Caleb, 25, who was interested in making explosives, and even made his own cannon. Nathan found that after a while, "blowing up stuff" got a bit boring and he started making rockets.

He said attending the Genesis Energy Realise the Dream event in Wellington recently with 28 other students was an amazing experience where he met like-minded people who got him exited about what science had to offer.

"I would really encourage people to get involved. It's not about being a geek, it's about doing something you're passionate about."

During the week, the students were taken around Wellington, visiting the city's attractions, such as the National Isotope Centre and the Karori Wildlife Sanctuary.

"My highlight for the week, though, was the day at Massey University, where we built our own light-seeking robotic car and a sterling engine which could generate electricity.
