  1. 1. Rocket Jet Impinging on a Surface

    University essay from KTH/Teknisk mekanik

    Author : Javier Capel Jorquera; [2022]
    Keywords : Rocket jet impinging on a surface; Favre-Averaged Equations; turbulence modeling; numerical considerations; Method of Characteristics; MOC; plate optimization;

    Abstract : With the continuous growth of the space industry and the introduction of reusable rockets, the number of rocket launches is expected to increase significantly in the following years. During rocket launching, the engine exhaust impinges on the launch structure producing a complex flow field. READ MORE

  3. 2. Investigation on how additive manufacturing with post-processing can be used to realize micronozzles

    University essay from Uppsala universitet/Ångström Space Technology Centre (ÅSTC)

    Author : Alan Bugurcu; [2022]
    Keywords : additive manufacturing; micronozzle; micro rocket nozzle; laser-powered powder bed fusion; electropolishing; supersonic micronozzle; supersonic micro rocket nozzle; titanium alloy; titanium-64; Ti-Al6-V4;

    Abstract : This is predominantly a qualitative study on the manufacturing of micronozzles with an additive manufacturing (AM) technique, namely the laser-powered powder bed fusion (PBF-LB).  Manufacturing of micronozzles with standard microelectromechanical system technology often results in 2.

    Abstract : Recent advances in plasma-based propulsion systems have led to the development of electromagnetic Radio-Frequency (RF) plasma generation and acceleration systems, called Helicon Plasma Thrusters (HPT). One of the pioneer companies developing this new type of space propulsion is T4i Technology for Propulsion and Innovation s.p.a. READ MORE

  5. 4. Supersonic Retro Propulsion Flight Vehicle Engineering of a Human Mission to Mars

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Hanna Marklund; [2019]
    Keywords : Supersonic retro propulsion; SRP; Mars; Human mission; Inflatable heat shield;

    Abstract : A manned Mars mission will require a substantial increase in landed mass compared to previous robotic missions, beyond the capabilities of current Entry Descent and Landing, EDL, technologies, such as blunt-body aeroshells and supersonic disk-gap-band parachutes. The heaviest payload successfully landed on Mars to date is the Mars Science Laboratory which delivered the Curiosity rover with an approximate mass of 900 kg. READ MORE
