Dong Kai / 董凯
Dong Kai / 董凯 is introduced in 【重听】朱雀三号副总师：火箭回收只有成与败，没有中间态 | S9E41 as 蓝箭航天’s 朱雀三号 overall deputy chief designer, responsible for the rocket’s overall design work. The episode uses him as an engineering source rather than a public biography source.
His contribution to the wiki is a detailed reusable-rocket operating view. Dong treats recovery as a binary engineering result, but he also argues that failed flight attempts can produce data on re-entry ignition, aerodynamic control, thermal environment, and terminal landing that directly improve the next vehicle.
He also explains why Zhuque-3 was designed for reuse from the beginning: liquid oxygen/methane, stainless-steel tanks, engine choice, recovery range, manufacturing cadence, and safety regulation are framed as parts of the same route toward large payload, high launch frequency, and lower cost.
