提箭回收Lift recovery

高可靠 · 深复用 · 全场景。把着陆载荷从箭体底部搬到顶部,火箭就不再需要一整套地面回收设施。Reliable, deeply reusable, site-agnostic. Move the landing load from the bottom of the airframe to the top, and the rocket stops needing a ground recovery complex.

原理Principle

一次返回,两套动力One descent, two propulsion systems

提箭法在火箭各级顶部设置一套副液体动力系统 —— 提箭发动机系统。初始返回阶段由底部主动力系统完成主要减速任务,提箭发动机系统配合完成箭体姿态的初步修正;进入近地阶段后,改由提箭发动机系统承担箭体空重,完成最终着陆。Lift recovery puts a secondary liquid propulsion system — the lift engine system — at the top of every stage. Through the initial return phase the base engines do the primary braking while the lift engines trim the vehicle's attitude; in the terminal phase the lift engines take over the empty vehicle's weight and fly it to touchdown.

回收发动机远离地面,箭体底部只需简化的裙边结构承重。着陆载荷从底部搬到顶部之后,大型地面辅助回收装置就不再是必需品,落地即在工位 —— 复用周期从「回收 — 转运 — 检修」压缩成「就地检修」。With the recovery engines far from the ground, the base of the airframe only needs a simplified load-bearing skirt. Once the landing load moves to the top, large ground recovery equipment stops being a prerequisite: the vehicle lands where it will be serviced, and the reuse cycle collapses from recover–transport–inspect down to inspect in place.

收益What It Buys

更高效 · 更经济 · 更通用More efficient, cheaper, more universal

  • 01

    更高效More efficient

    着陆姿态修正响应更迅速 —— 力矩更大。回收动力位于箭体顶部,离质心更远,同样的推力能产生更大的控制力矩,着陆段的姿态修正更快收敛。Attitude corrections respond faster, because the moment arm is longer. With the recovery engines at the top of the airframe, further from the centre of mass, the same thrust produces a larger control moment and the terminal phase settles sooner.

  • 02

    更经济More economical

    无需大型地面辅助回收装置 —— 静稳定特性。推力作用点在质心之上,箭体在下降段呈静稳定悬挂状态,地面不必为每个着陆点重复建设重型资产。No large ground recovery equipment is required, thanks to static stability. With thrust applied above the centre of mass the vehicle hangs in a statically stable state on descent, so heavy assets need not be rebuilt at every landing point.

  • 03

    更通用More universal

    适用地外行星回收场景 —— 不依赖空气动力。全程不借助大气产生的气动力与地面辅助设施,月球、火星这类无大气或稀薄大气环境同样适用。It works for recovery on other planets, because it never relies on aerodynamics. No atmospheric lift or drag and no ground support are needed, so airless and thin-atmosphere environments such as the Moon and Mars are equally in scope.

出发点Starting Point

三个痛点,三条解法Three pain points, three answers

行业痛点很清楚:太空运输成本高、效率低,航班化尚未实现。三条症结都指向同一个地方 —— 地面。The industry's problem is not subtle: space transport is expensive, slow, and nothing like an airline yet. All three symptoms trace back to the same place — the ground.

  • 地面设备冗余Redundant ground equipment

    痛点Pain point
    传统回收方式需要大型地面辅助回收设备,导致重型资产冗余。Conventional recovery needs large ground support equipment, so heavy assets pile up unused.
    精简投入Trim the investment
    回收发动机远离地面,箭体底部简化裙边结构承重。The recovery engines sit far from the ground and the base of the airframe carries load through a simplified skirt.

  • 周转效率低Slow turnaround

    痛点Pain point
    发射后维护时间长,难以实现航班化连续运营。Post-flight servicing takes so long that continuous, airline-style operation is out of reach.
    快速周转Fast turnaround
    箭体自搬运,返场回收快速复用,显著缩短任务间隔。The airframe transports itself, comes back for quick reuse, and cuts the gap between missions sharply.

  • 回收条件需求高Demanding recovery conditions

    痛点Pain point
    传统回收方式依赖大气、地面,难以满足多场景运载需求。Conventional recovery leans on the atmosphere and on prepared ground, which rules out most mission scenarios.
    行星通用Any planet
    广泛适应地球、地外(月球、火星)的发射与着陆。One method covers launch and landing on Earth and beyond — the Moon and Mars included.
  • 高频运营High cadence 快速复用运载平台,大幅缩短任务间隔,实现航班化发射。A rapidly reusable platform that shortens the interval between missions enough to launch on a schedule.
  • 低成本运营Low operating cost 提升复用效率,降低单次运输成本,推动商业化普及。Better reuse efficiency drives down the cost of a single flight and makes commercial use ordinary.
  • 全场景运输Every mission type 支持载人、货运、应急及深空运输,构建常态化太空交通体系。Crew, cargo, emergency response and deep space — the basis of routine traffic to orbit.

这三条是航班化太空通勤平台必须同步满足的核心需求。提箭回收方案的完整表述则是 高可靠 + 深复用 + 全场景。An airline-grade space commuting platform has to satisfy all three at once. Stated in full, lift recovery means high reliability, deep reuse, any site.
