Close-up view of a friction stir weld tack tool. The bulkhead and nosecone of the Orion spacecraft are joined using friction stir welding. Joint designs. Friction stir welding (FSW) is a solid-state joining process that uses a non-consumable tool to join two facing workpieces without melting the workpiece material.
Spray transfer GMAW. Gas metal arc welding (GMAW), sometimes referred to by its subtypes metal inert gas (MIG) and metal active gas (MAG) is a welding process in which an electric arc forms between a consumable MIG wire electrode and the workpiece metal(s), which heats the workpiece metal(s), causing them to fuse (melt and join).
The Canadian Welding Bureau, through CSA Standards W47.1, [3] W47.2 [4] and W186, [5] specifies both a WPS and a Welding Procedure Data Sheet (WPDS) to provide direction to the welding supervisor, welders and welding operators. The WPS provides general information on the welding process and material grouping being welded, while the WPDS ...
Concept art of MiG 1.44 in flight. The MiG 1.44 had its origins in the early 1980s, when the U.S. Air Force began developing a successor to the F-15 Eagle under the Advanced Tactical Fighter (ATF) project, which would eventually result in the supermaneuverable and stealthy, albeit costly, F-22 Raptor that first flew in 1997.

The 1953 Avro Lincoln shootdown incident was the shooting down of a British Avro Lincoln four-engined bomber which had intruded into East German airspace during a training mission on 12 March 1953. While the aircraft was flying on the Hamburg-Berlin air corridor over East Germany it was shot down by a Soviet Mikoyan-Gurevich MiG-15 fighter.
The design is derived from the company's PAK FA proposal, which was rejected in favor of Sukhoi's, along with lessons learned from the cancelled Mikoyan MiG-1.42/1.44. It was supposed to replace the Mikoyan MiG-29 and MiG-35 and be a more affordable complement to the PAK FA, which became the Sukhoi Su-57. [2]
An engine failure forced Jack McKay, a NASA research pilot, to make an emergency landing at Mud Lake, Nye County, Nevada, [140] in the second North American X-15, AF Ser. No. 56-6671 on flight 2-31-52. The aircraft's landing gear collapsed and the X-15 flipped over on its back.
