SpaceX星际飞船超级重型助推器7部发动机同时点火_我的网站

A | 9月20日消息,当地时间周一,SpaceX在对星际飞船系统原型的7号超级重型助推器进行静态点火测试时,首次同时启动7部猛禽发动机,这也是公司同时启动火箭发动机数量最多的一次测试。星际飞船是高度有50米的可重复使用航天器,将由70米长、搭载33部猛禽发动机的超级重型助推器送入轨道。SpaceX最近一直在测试7号助推器,为计划中的星际飞船系统首次轨道飞行做准备。 At least one person is dead after heavy rain and thunderstorms swept through Las Vegas over the weekend, the city confirmed in a statement on Sunday.The person, who was found Saturday morning, was believed to have drowned, Las Vegas spokesperson Jace Radke said in a statement. Las Vegas Fire and Rescue posted Sunday on X (formerly Twitter) that they responded to 24 swift water rescue incidents, which included 30-35 vehicles stranded in the water and 10-12 people rescued from standing or moving water. The National Weather Service said Sunday that 2.55 inches of rain were recorded at the airport. Las Vegas has already seen 3.99 inches of rain so far in 2023, which is 1.17 inches above normal and only 0.19 inches below the city's normal annual precipitation, the National Weather Service said.

B | 他还补充说,公司下一次星际飞船系统原型大型测试将是“全堆栈发射前状态合练,然后在几周内同时启动33部发动机。”马斯克所说的“全堆栈”包括位于超级重型助推器顶部的星际飞船,它们共同构成了世界上最高的火箭,总高有120米。SpaceX最近完成的这次发动机静态点火测试是8月31日火箭发动机点火数量的两倍。

C | 在那次对超级重型助推器进行静态点火测试时,SpaceX启动了三部猛禽发动机,这也是公司首次对超级重型助推器上搭载的多部发动机同时进行静态点火测试。此前,SpaceX曾在8月9日的一次静态点火测试中同时启动星际飞船6部猛禽发动机中的2部。

D | SpaceX还没有公布对星际飞船系统进行全栈测试的预计日期。但公司表示,它的目标是在未来几个月内对飞船原型进行首次轨道测试。
