Modeling and Simulation Analysis of Ascent Process of New Latex Balloon
Latex balloons,as a commonly used meteorological sounding balloon,usually rise continuously until they explode under net buoyancy after being released.The flight time is short and cannot fly flat.By installing an ex-haust valve on the balloon and exhausting during the ascent process,net buoyancy can theoretically be discharged to achieve flat flight.Therefore,this article established the systematic thermodynamic model,dynamic model,geometric model,and exhaust model for the ascent process and conducts numerical simulations.The simulation analyzed the changes of helium temperature,ascent speed,balloon volume,and altitude during the ascent process.The simulation results show that it is feasible to realize the level flight of latex balloon by exhausting during the ascent process,and the simulation results have guiding significance for the system design and height control algorithm design of latex bal-loon.
