Recovery Range Payload Tradeoff

Recovery range payload tradeoff is the source’s account of how a reusable rocket’s landing-site distance changes usable payload and propellant reserve. 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, 董凯 says 朱雀三号 used a roughly 390 km recovery range on its first flight mainly for safety.

Dong’s source-scoped estimate is that a fuller-performance Zhuque-3 recovery case would put the recovery field around 550-600 km away. The first flight also landed with roughly 10 tonnes of propellant; if that reserve had been used for more payload work, the payload could rise by about 2-3 tonnes. He gives a rough rule that every additional 10 km of recovery range adds about 150 kg of payload capacity for Zhuque-3.

Key Claims

• Recovery-site placement is not a logistics detail; it changes the split between payload work, boostback/descent energy, and landing reserve.
• Conservative early tests may preserve safety margin while leaving payload performance unused.
• A reusable-rocket route needs recovery-field expansion and flight data before its advertised capacity can be fully exploited.
• Payload, recovery probability, and public-safety boundaries have to be optimized together rather than separately.

Connections

• Zhuque-3 / 朱雀三号, LandSpace / 蓝箭航天, and Dong Kai / 董凯 - rocket, company, and source speaker.
• Rocket Recovery Route Choice - route selection changes where mass, propellant, and infrastructure burdens sit.
• Reusable Rocket Economics - payload and recovery cadence affect whether reuse beats disposable launch.
• Reuse-First Rocket Design - range and reserve choices have to be designed into the vehicle and mission profile.
