A vertical wind tunnel for indoor skydiving has at least one recirculating airflow plenum. The airflow plenum includes a first vertical member housing a flight chamber, a top horizontal member, a second vertical member, and a bottom horizontal member. The bottom horizontal member has a first section and a second section. A corner section connects the second section of the bottom horizontal memberwith the first vertical member. The second section of the bottom horizontal member contracts the airflow travelling through the bottom horizontal member between the first section and its exit to the corner section. The corner section further contracts the airflow exiting the second section of the bottom horizontal member towards the first vertical member.
一种再循环竖直风洞,用于室内跳伞并具有至少一个再循环气流气室。气流气室包括容纳飞行舱的第一竖直构件、顶部水平构件、第二竖直构件以及底部水平构件。底部水平构件具有第一部段和第二部段。拐角部段将底部水平构件的第二部段与第一竖直构件相连接。底部水平构件的第二部段使途经底部水平构件的气流在第一部段和第二部段到拐角部段的出口之间收缩。拐角部段进一步使朝向第一竖直构件离开底部水平构件的第二部段的气流收缩。
