    Recoverable rockets for reuse

    SpaceX started the trend for reusable rockets and is close to recovering the 1st stage of their flagship rocket Falcon 9. Now it turns out Airbus has been working on the same sort of concept. The project is called Adeline and they have conducted demonstration flights. In fact they already have a patent application titled, Simplified Reusable Module for Launcher.

    Details are contained in a patent application titled, Simplified Reusable Module for Launcher. Media reports say the company has been working on the project, which is code named Adeline, since 2010 and has conducted demonstration flights. The system could be used on any rocket, including the Ariane 6 that is now under development.

    Airbus Defence and Space on June 5 unveiled the product of what it said was a five-year effort to design a reusable Ariane rocket first-stage engine and avionics package, a project company official said was stimulated by SpaceX’s work on reusable rockets.

    Airbus officials said they believe they have resolved some of the issues inherent in Hawthorne, California-based SpaceX’s reusability effort, notably the exposure of the first stage engine to high-speed stresses as it descends through the atmosphere to its landing zone.

    Airbus’s Adeline — short for Advanced Expendable Launcher with Innovative engine Economy — also imposes a much smaller performance penalty on its rocket than is the case for SpaceX’s reusable Falcon 9 first stage, all the while reusing 80 percent of the stage’s economic value — the engine, avionics and propulsion bay.

    Which is something SpaceX has never had a problem with. The actual landing, yes.

    I wonder if the whole shuttlecock thing on SS2 might make better sense for something like this...


    I really like the SpaceJet concept even better

    They didn't start the trend, but they were the first that actually has working technology to achieve it.
    Shuttle and Buran were originally being designed for reusability, but fell short with only partial reusability.
    DC-X was supposed to be fully re-usable, but never materialized.

    I stand corrected

    China has joined the bandwagon as well

    http://www.spacedaily.com/reports/Ch...ogies_999.html

    China is working on its own reusable rocket technologies, a source close to the research told Xinhua Thursday.

    Chinese experts have already built a prototype model to test theories on the reusable rocket booster's landing subsystems. They have completed "experimental verifications" using "multiple parachutes" supposedly attached to the booster, a source with China Academy of Launch Vehicle Technologies (CALT), developer of China's Long March rocket series, said.

    "The experiment has laid solid foundation for the realization of reusable rockets in the country," the source said.

    "China tests grid fins with launch of Gaofen-7 imaging satellite"

    https://spacenews.com/china-tests-gr...ing-satellite/

    A Chinese Long March 4B delivered an Earth observation into orbit satellite late Saturday, with grid fins guiding the descent of the rocket’s first stage.

    The launch took place at 11:22 p.m. at the Taiyuan Satellite Launch Center in north China. For the first time the Long March 4B first stage carried a grid fin system to constrain the area in which it falls.

    Most of China’s launches take place at thee centers far inland, resulting in debris landing downrange. The grid fins are to both reducing risk and mark a step toward future retropropulsive landings and launcher reusability.

    Not for reusability, just to reduce the number of people they kill with falling boosters. Because it looks bad.

    From the article - "The hypergolic Long March 4B is designed and manufactured by the Shanghai Academy of Spaceflight Technology (SAST). It is also developing a new variant of its new generation Long March 6 kerolox launcher. Utilizing landing legs and grid fins it will be capable of Falcon 9-style vertical takeoff and vertical landing.

    The China Academy of Launch Vehicle Technology (CALT) tested grid fins on a Long March 2C in July. CALT is developing its own retropropulsive landing capabilities for use on the planned Long March 8.

    SAST and CALT are subsidiaries of the China Aerospace Science and Technology Corporation (CASC), China’s main space contractor.

    In 2017 CASC released a space transportation roadmap, outlining ambitions to make its launch vehicles fully reusable by 2035."
