全球首款，在汉问世

Core Viewpoint - Wuhan Tianjiang Technology Co., Ltd. has successfully developed the world's first waterproof and sandproof electric backup parachute opener, named "Tianjiang 2025," which has passed over 1000 hours of extreme environment testing, achieving international leading standards [1][5]. Group 1: Product Development - The "Tianjiang 2025" product overcomes the limitations of traditional parachute equipment in harsh environments, providing more reliable safety guarantees for extreme sports such as high-altitude parachuting and wingsuit flying [1]. - The development team spent several years and traveled extensively to understand the actual needs of parachutists, conducting tests in various extreme conditions, including from the extreme cold of the northern desert to the humid tropical forests [1][5]. Group 2: Testing and Reliability - The product underwent multiple extreme environment tests, including a 10-meter water depth static pressure test for 24 hours and high-speed water impact simulations, with no water or sand penetration observed [5]. - The technology team integrated several cutting-edge technologies, such as superhydrophobic nano-coating materials and intelligent sensor systems, to enhance the product's performance in complex environments [5]. Group 3: Application and Patent - The opener is suitable for various extreme environments, including water parachuting, desert parachuting, and polar exploration, maintaining reliability even in sandstorms and low-temperature high-humidity conditions [9]. - The company is applying for five patents related to this innovative technology, in addition to having previously obtained 16 patent achievements [9].
