20th century

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...

I thought we already had a THAAD related topic, but I can't find it, so I'll put this old [1992] Thiokol Corp report on the SPBD booster program here.

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...

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...

Before we got LCS, their were a number of concepts that involved the use of one or more motherships acting as the center for a large number fo smaller, and more expendable combat vessels-- can anyone point to a source for information and images about these earlier concepts?

To start this thread off, here's a recent article on Nuclear Merchant Ships (part of a series on the peaceful uses of Nuclear power). Includes information on the only four such ships to have been built so far: NS Savannah, USA; Mutsu, Japan; Sevmorput, Russia; and the Otto Hahn, Germany. Also...

Wings of Russia Studio has created a fascinating 18-part, so far, documentary series titled Wings of Russia that documents the history of Russian and Soviet aviation. The episodes are available on DVD in the Russian and English languages. Alas, it is only seems to be available for order in the...

Greetings All - A friend passed along some scans from the San Diego Air & Space Museum which included a number of Convair designs I was not aware of. First off is the Model 103... Enjoy the Day! Mark

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...

I am sure that many remember this Popular Mechanics article or one of the many like it back then on a rumoured type of Russian concrete sub with 200 mph Shkval rocket torpedoes: Concrete Submarines Cheap and deadly, these stealthy boats could shift the balance of naval power. December 1998...

In 2006 Nick Cook published an article in Janes, etc. describing a Lockheed project called Penetrating High Altitude Endurance (PHAE). This was described as a HALE UAV much like Polecat, Tier 3, Tier 3-, etc. etc. etc. Source: http://www.janes.com/defence/news/idr/idr060321_1_n.shtml Here's...

Many years ago I read about SWATH being the ideal hull form for future naval ships because of their superior seakeeping ability to monohulls. There stability made them ideal for carriers according to an article I read in Proceedings of the American Naval Institute. We breifly saw concept art...
