Detroit went bankrupt in 1931 in the aftermath of the great stock-market crash and an investment banker, Bob Gross and some coinvestors then bought Lockheed for $40,000. The company experienced dramatic expansion through the war years reaching over 90,000 employees by the middle of World War II, during which they built nearly 20,000 aircraft. This then rapidly scaled down following the end of the war so that by 1946 there were less than 20,000 staff on the payroll. Three aircraft dominated this era in the company: the P38 Lightning, the Hudson and the Constellation transport – it was in a Constellation that Orville Wright made his last flight.
Without input from men like von K´arm´an, aeronautical engineering could not have come so far as it has so quickly. 4 Two Great Aerospace Companies The origins of the great aerospace companies that exist today can mostly be traced back to the efforts of a few key individuals, such as those mentioned above. Their growth to major international operations owes much to the large numbers of aircraft built during World War II and subsequently to the consolidation of the many firms that were operating in the industry at that time.
Significant reductions in solution time have been gained for structural mechanics problems due to advances in preconditioned Krylov methods. Similar advances have been made in CFD using domain decomposition and Newton–Krylov methods. As Jameson (2001) observes, improvements in algorithm design alone resulted in a two order of magnitude improvement in computational speed for Eulerbased fluid dynamics calculations between 1980 and 1990. Consider the fundamental matrix operations that lie at the heart of a linear finite element solver.
