In a few days, weather permitting, NASA’s stratospheric balloon STO2 will be launched from Antarctica to the edge of space to measure cosmic far infrared radiation in order to find out more about how stars and planets come to be.

The STO2 design has been headed by the University of Arizona, with vital contributions from SRON Netherlands Institute for Space Research (Utrecht and Groningen) and Delft University of Technology.

One of the tools is a receiver at 4.7 terahertz, one of the three frequencies that help find the presence of elements in space, including electrically neutral atomic oxygen. The localisation of the latter can be achieved using a 4.7 terahertz receiver, the first time such a tool will be brought to the edge of space for an unrestricted view, for two weeks.

As well, The teams of Alexander Tielens (Leiden University) and Floris van der Tak (SRON/University of Groningen) will help analyse the observations.

Student develops airbag for falling elderly

Filed under: General by Orangemaster @ 2:14 pm

elderly_man

Delft University of Technology related designer Heike Vallery together with Dutch startup WOLK have designed an airbag for falling elderly. As they fall a cushion fastened to their hips pops upon and softens the blow, reducing the chance of hip injuries.

Vallery and WOLK studied the fall algorithm that anticipates instability so that their airbag deploys on time. They claim that the airbag is comfortable to wear under most clothing and the cushions can deploy from the left, the right and the rear, as seen in this very short video. They are still at the prototype stage, but by 2017 they’ll have a working model.

Dutch students set world record with solar-powered boat

Filed under: Dutch first,Sustainability by Orangemaster @ 3:03 pm

Solar-Boat

This week, the Delft University of Technology’s Solar Boat Team has set a world record of 50.5 kilometres per hour on Day 5 of the Dutch Solar Challenge in Drachten, Friesland. There wasn’t any previous record, making this a sweet victory for the students.

This world record will also be added to the Guinness World Records as the first record ever set for a solar-powered boat. Second place in the challenge was 42 kilometres per hour set by a team from Leeuwarden, Friesland and 30,3 kilometres per hour was clocked by a team from Slochteren, Groningen.

The Delft team also won ook the innovation award thanks to the technology it used, which included two hydrofoils placed one behind another instead of next to each other, which had the boat ‘skating over the water’.

Stainless steel 3D printed bicycle comes to life

Filed under: Bicycles,Dutch first by Orangemaster @ 2:02 pm

Arc-Bicycle

A team of students from Delft University of Technology have designed and produced a fully functional 3D printed stainless steel bicycle. It looks like a robot did some heavy metal basket weaving.

At the beginning, we noticed the project was being welded at MX3D in Amsterdam, the folks working on a 3D printed steel bridge.

The Arc Bicycle is apparently the first ever 3D printed metal bicycle to be produced using a welding process.

Prototype back pack filters the air using plants

Filed under: Design by Orangemaster @ 3:17 pm

Aloe Vera

Five Dutch students of the Delft University of Technology are designing a back pack with a plant in it which would replace the use of gas masks in polluted cities. “The bag allows fine particles to be filtered out and cleans the air,” said team leader Marnix de Kroon. It provides instant fresh air to the wearer thanks to a filter that sifts it through the roots of a plant inside the back pack.

Plant-wise, “it seems that aloe vera may be a possibility,” De Kroon explained. An expert was quick to cut the plant bag idea down, claiming it wouldn’t be useful and the filter itself could ‘weed out’ 99.9 percent of the fine particles.

The team still believes that in cities like Beijing and Tehran, which have serious pollution problems, could be their main market. After all, the prototype did bag a Dutch design prize.

Dutch students break European rocketry record

Filed under: Dutch first by Orangemaster @ 7:00 am

DARE

On 16 October in the afternoon, the Delft Aerospace Rocket Engineering (DARE) student society of the Delft University of Technology broke a European record in amateur rocketry. The students successfully launched a rocket into space that attempted to reach the Kármán line at 100 kilometers in altitude.

The first attempt made by the students on Thursday was thwarted by problems with a motor valve, which is why after fixing it, they made another attempt the next day. The seven-meter-long Stratos II+ rocket uses a mix of sorbitol and paraffin for fuel. It reached a speed of 100 km/h in 0.85 seconds, with a top speed of 3000 km/h.

In a few years, the DARE team wants to go into space, and to be able to do that they need to reach the Kármán line. The sky’s the limit now.

Aircraft that could fly Amsterdam to Perth non-stop

Filed under: Aviation,Design by Orangemaster @ 1:34 pm

KLM-AHEAD

KLM and Delft University of Technology have presented designs for an aircraft that could transport passengers non-stop from Europe to Australia. It looks like a flying squirrel swallowed a hammerhead shark and then an Airbus or a Boeing, you choose.

This AHEAD (Advanced Hybrid Engine Aircraft Development) aircraft, would carry 300 passengers over 14,000 kilometres, about the distance from Amsterdam to Perth. Its design features two sets of wings – a small pair by the nose and a large set at the rear – that blend into the body. The team also proposes a hybrid engine to replace conventional turbofan engines.

KLM has previously worked with Dutch designers Hella Jongerius and Marcel Wanders to create cabin interiors and tableware.

Dutch students win electric car competition in the UK

Filed under: Automobiles,Sustainability by Orangemaster @ 11:01 am

Engineering students from the Delft University of Technology have done it again, winning this year’s Institution of Mechanical Engineers’ Formula Student competition for the second time in a row.

The Formula Student competition requires engineering students to design, build and race a single seat racing car in just one year. Cars are assess on their acceleration, endurance, fuel economy, design and business cases.

Thousands of the world’s best young engineers were at Silverstone, Northamptonshire, England on 8-12 July. There were 135 teams in total, with 49 from the UK and teams from as far as Australia, Turkey and Ukraine. Team Delft claimed the prize at Silverstone this weekend with a total score of 909.3 out of a total score of 1,000 points. Germany’s UAS Zwickau claimed second place with 792.5 points, University of Stuttgart came third with 750.8 and the University of Bath was the top UK team, coming fourth with 748.4 points.

World record for Dutch hydrogen fuel cell car

Filed under: Automobiles,Dutch first by Orangemaster @ 11:33 am

TU-delft-race-car

Dutch racing driver Jan Lammers recently had the honours of racing the Delft University of Technology’s Forze VI, a student built hydrogen powered racing car on the world-famous Nürburgring racetrack in Germany. Lammers completed the 21 kilometre-long endeavour under 11 minutes, a world first for a hydrogen fuel cell powered car.

Although the Forze VI reached top speeds of 170 km/h around the track, the 50 students who have made this car a reality believe it can do so much more. Besides getting the car to reach the theoritically possible speed of 220 km/h, the Formula Zero Team Delft plan to race against combustion engine powered cars in various races, with the ultimate goal being the 24 hour Le Mans.

Ambulance drone could drastically reduce response times

Filed under: Health,Science by Orangemaster @ 11:29 am

Belgian engineering student Alec Momont, a graduate at the Delft University of Technology, has developed an ‘ambulance drone’, a defibrillator which can fly at 100 km/h able to reach heart attack victims very quickly. It uses the GPS of emergency calls to navigate.

This drone or ‘Unmanned Aerial Vehicle’ (UAV), can get a defibrillator to a patient within a 12 km2 zone within a minute, reducing the chance of survival from 8 percent to 80 percent. Momont explains that it is the relatively long response time of emergency services of around 10 minutes, while brain death and fatalities occur with four to six minutes, which makes the fatality rate so high.

I’m easily convinced. It reminds me of an evening in the pub recently chatting outdoors and watching an ambulance trying to find an address in Amsterdam West with their GPS but having to ask us for directions. The police was following them, got lost as well and asked us for those same directions. I’m sure that wasted at least 10 minutes.

One drone is expected to cost around 15,000 euro and could also carry other medical tools.
