    The general Cyberpunk thread

    Given the distinct trend that real world events have taken lately, I thought it was long since time for a dedicated cyberpunk thread.

    Brditschka/HB-Flugtechnik Designations

    Brditschka, HB-Flugtechnik, and HB-Aircraft The Brditschka corporate history is somewhat confused because of two separate lines of interest. Heinrich Wenzel Brditschka (born 1930) was interested in jewellery but was also an amateur aircraft builder. The first company was HW Brditschka OHG which...

    Igor Sikorsky's first helicopters (1909-1910)

    Presenting Igor Sikorsky as the father of the helicopter is not so far-fetched as it may seem. His 1939 tests of the VS-300 were hardly the first successful flights of a rotorcraft, but they marked the first time someone built a helicopter, flew it sufficiently high and long and repeatedly to...

    Rocket Engines, concepts, experiments (past/present/future)

    So I found an engine program which wasn't on Astronautix by randomly reading documents on the US Space & Rocket Center's digital archives at UAH. The document in question is: Launch Vehicle Engines Project Development Plan MA001-A50-2H (1 January 1967) And here's the link to download the...

    US Navy/USMC/US Army Sea Basing Concepts

    Fun. I liek the C-5A for scale. Clearly we need a folding wing C-5C to fit below decks. ;D

    Royal Navy nuclear surface ships

    although no pictures exist there is supposed to be a model of the proposed RFA replenishment ship with nuclear power in the massive Greenwich collection. I have never been able to get to see this model, but based on some small drawings of mercantile UK reactor designs in an old Airfix magazine...
