Horten Ho 229 EditThe Horten H.IX, RLM designation Ho 229 (often called Gotha Go 229 because of the identity of the chosen manufacturer of the aircraft)
Was a German prototype fighter/bomber designed by Reimar and Walter Horten and built by Gothaer Waggonfabriklate in World War II. It was the first pure flying wing powered by jet engines.
The design was a response to Hermann Göring's call for light bomber designs capable of meeting the "3×1000" requirement; namely to carry 1,000 kilograms (2,200 lb) of bombs a distance of 1,000 kilometres (620 mi) with a speed of 1,000 kilometres per hour (620 mph).
Only jets could provide the speed, but these were extremely fuel hungry so considerable effort had to be made to meet the range requirement. Based on a flying wing, the Ho 229 lacked all extraneous control surfaces, lowering drag. It was the only design to come even close to the 3×1000 requirements, and received Göring's approval. Its ceiling was 15,000 metres (49,000 ft).
Since the appearance of the B-2 Spirit flying wing stealth bomber in the 1990s, its similarities in role and shape to the Ho 229 has led many to retrospectively describe the Ho 229 as "the first stealth bomber".
A static reproduction of the only surviving Ho 229 prototype, the Ho 229 V3, in American hands since the end of World War II was later tested by the U.S. military who found the basic shape, paint and laminating adhesive composition of the mockup copy would provide for 37% reduction in detection range against the British Chain Home radar of the 1940s, but no significant stealth benefit against most other contemporary radar systems.
Stealth technology Edit
After the war, new scientific developments led to the concept of designing an airframe that could bypass radar. It was discovered that a jet-powered flying wing design such as the Horten Ho 229 will have a smaller radar cross-section to conventional contemporary twin-engine aircraft. This is because the wings blended into the fuselage and there were no large propeller disks or vertical and horizontal tail surfaces to provide a typical identifiable radar signature. In addition, Reimar Horten said he mixed charcoal dust in with the wood glue to absorb electromagnetic waves (radar), which he believed could shield the aircraft from detection by British early warning ground-based radar that operated at 20 to 30 MHz (top end of the HF band), known as Chain Home radar.
Engineers of the Northrop-Grumman Corporation had long been interested in the Ho 229, and several of them visited the Smithsonian Museum's facility in Silver Hill, Maryland in the early 1980s to study the V3 airframe. A team of engineers from Northrop-Grumman ran electromagnetic tests on the V3's multilayer wooden center-section nose cones. The cones are three quarters of an inch (19 mm) thick and made up of thin sheets of veneer. The team concluded that there was indeed some form of conducting element in the glue, as the radar signal attenuated considerably as it passed through the cone.
