Xinhua Beijing, May 23 (Wang Ying) reporter learned from the Institute of Aerospace Information of the Chinese Academy of Sciences that in the second comprehensive scientific investigation of the Qinghai-Tibet Plateau recently carried out in Namco, the new technology of moored aerostat developed by the Academy was formally applied, reaching an altitude of 7003 meters in the early morning of May 23. This altitude is also known as the world record of the standing altitude of the same type of aerostat.
According to scientific researchers, in order to better use the new technology to serve the second Qinghai-Tibet Science Examination, the Academy independently developed three kinds of tethered aerostats: "Jimu 1", "Jimu 2", "Jimu 3". The volume of the three types of aerostats is from small to large, the standing height is from low to high, and the system complexity and technical difficulty are gradually increasing.
Reporters learned that the implementation of this task is one of the "Jimu No. 1". According to reports, "Jimu No. 1" is an experience version of the plateau, with a volume of 2300 cubic meters. It is the first application of streamlined aerostats in the Qinghai-Tibet Plateau. It can carry scientific instruments for vertical profiling and aerial observation, and will accumulate technical exploration and application for the subsequent development of aerostats.
Unlike "Jimu No. 1", Jimu No. 2 (under development) is a customized version of scientific research. It is tailored for the second Qinghai-Tibet scientific research. It is designed to stand at an altitude of 7000-7500 meters. It can be used at Lulang Station in southeastern Tibet, Qomolang Station in central Tibet, Namcho Station and Mustag Station in Western Tibet. "Jimu No. 3" (in development) is a breakthrough type of technology. The design altitude of the platform will exceed the height of Everest. The technical difficulty of the platform, the altitude of the platform and the possible results of carrying loads will be breakthroughs.
Reporters learned that in order to create this record, the members of the scientific examination team experienced many tests, such as cold and anoxic, snowstorm, strong solar radiation, continuous observation day and night. In its first test flight, the Polar Eye I has reached an altitude of 6608 meters. In the process of lifting-off, various instruments will synchronously observe the atmospheric physics and atmospheric parameters of Namco Basin, providing a basis for the study of climate and environmental changes in the Qinghai-Tibet Plateau.
