If you are using this predictor in a commercial setting, please read this page. Written by Adam Greig for CUSF in March 2010. Before we determine how many helium balloons it would take to lift a person, let's start with some theory. Helium is typically stored in high pressure containers like K-cylinders. Satellite Tracker - This is by far the best option for tracking your weather balloon payload. The weather balloon flies in average about 80 kilometres as the crow flies. Severe Weather Preparedness In the United States, most flights use helium due, because it's easier to find commercial and it's much safer to . A weather balloon or sounding is a sort of mobile weather station in that it carries instruments into the upper air in able to record observations of weather variables (like atmospheric pressure, temperature, humidity, and winds), then sends back this data during its suborbital flight. Hydrogen is cheaper and can give more lift due to its lower density, however, hydrogen is very flammable and must be handled with extreme care. Credit also to Rich Wareham for work on the predictor. The smaller the balloon's initial volume, the higher it will go before it reaches its burst volume. next to the burst diameter or drag coefficient boxes to use a custom value, otherwise the As an example, let's say you want to launch a payload that weighs 1200 grams (including the weight of the parachute, rigging, etc.). Balloon Trajectory Forecasts. Next the Balloon Performance Calculator calculates the altitude at which the balloon will burst. If you don't believe us, here's the actual video footage to blow your mind: Knowing the distance traveled by the house, we could estimate its average speed with the speed calculator. See these pages for more details: Promoting science and technology education through spaceflight and weather balloons. Most flight predictions tools use the Global Forecast System (GFS) weather models to supply their predictions. We decide we don't want to rent two 55 cu.ft. Some parts of code taken from old landing prediction software, credit to Rob Anderson, Fergus Noble and Ed Moore. (ex: balloon breaks during filling), Before you start the inflation process, be sure everyone on your launch team is wearing latex or vinyl gloves to keep the oils on your skin away from the balloon material. If you're performing these calculations by hand, you can surely use the lifting force of one gram per liter; however, our helium balloons calculator uses a more precise value of 1.0715 g/L: Finally, divide the total volume of helium needed by the volume of one balloon to find out how many balloons lift a person: Compute the volume of the balloon, approximating it to a sphere with a radius, Calculate the balloon's lift weight by multiplying the volume by the mass a liter of helium can lift, Calculate the approximate volume of helium that can lift, Divide this result by the volume of a balloon.
