  New Materials Architectures Sought to Cool Hypersonic Vehicles

  Hypersonic vehicles fly through the atmosphere at incredibly high speeds, creating intense friction with the surrounding air as they travel at Mach 5 or above – five times faster than sound travels. Developing structures that can withstand furnace-like temperatures at such high speeds is a technical challenge, especially for leading edges that bear the brunt of the heat. To address this thermal challenge, DARPA recently announced its Materials Architectures and Characterization for Hypersonics (MACH) program. The MACH program seeks to develop and demonstrate new design and material solutions for sharp, shape-stable, cooled leading edges for hypersonic vehicles. A Proposers Day describing the program will take place January 22, 2019 in Arlington, Virginia: https://go.usa.gov/xEcEy. “For decades people have studied cooling the hot leading edges of hypersonic vehicles but haven't been able to demonstrate practical concepts in flight,” said Bill Carter, program manager in DARPA's Defense Sciences Office. “The key is developing scalable materials architectures that enable mass transport to spread and reject heat. In recent years we've seen advances in thermal engineering and manufacturing that could enable the design and fabrication of very complex architectures not possible in the past. If successful, we could see a breakthrough in mitigating aerothermal effects at the leading edge that would enhance hypersonic performance.” The MACH program will comprise two technical areas. The first area aims to develop and mature fully integrated passive thermal management system to cool leading edges based on scalable net-shape manufacturing and advanced thermal design. The second technical area will focus on next-generation hypersonic materials research, applying modern high-fidelity computation capabilities to develop new passive and active thermal management concepts, coatings and materials for future cooled hypersonic leading edge applications. Both technical areas will be described in a Broad Agency Announcement solicitation expected in mid-January 2019 on DARPA's FedBizOpps page here: http://go.usa.gov/Dom. The MACH program seeks expertise in thermal engineering and design, advanced computational materials development, architected materials design, fabrication and testing (including net shape fabrication of high temperature metals, ceramics and their composites), hypersonic leading-edge design and performance, and advanced thermal protection systems.

  Airbus Calls For European Cooperation On Future Military Rotorcraft

  Concerns that U.S. industry could muscle in on NATO plans for a medium-lift helicopter for the 2030s and beyond has sparked Airbus to call for a European solution. Airbus Helicopters says it has backing from the French, German and Spanish governments to bid for grants from the European Defense Fund... https://aviationweek.com/defense-space/missile-defense-weapons/airbus-calls-european-cooperation-future-military-rotorcraft

  David J. Bercuson: Why Japan is building its military, fast

  David J. Bercuson With 18 diesel electric submarines, four so-called “helicopter destroyers” that look suspiciously like small aircraft carriers, 43 destroyers and destroyer escorts, 25 minesweepers and training ships, fleet oilers, submarine rescue ships and other vessels, Japan's navy — the Maritime Self-Defense Force — is the second largest in Asia and one of the largest in the world. It is also highly advanced technologically and is growing all the time. The two 27,000 ton Izumo-class helicopter destroyers, the largest in the fleet, with flat flight decks and islands on the starboard side of the vessels, are small compared to the United States Navy's Nimitz-class aircraft carriers (approximately 100,000 tons) or Britain's new Queen Elizabeth-class carriers (65,000 tons). But if equipped with the new short-take-off-and-vertical-landing F-35B stealth fighter they will still pack a powerful punch. And Japan is considering adding more of these aircraft carriers to its fleet and advanced U.S.-style Aegis class destroyers, capable of shooting down medium-range ballistic missiles. The irony in all of this is that Japan's post Second World War constitution still contains a provision — Article 9 — that prohibits it from possessing any offensive military capability. In the early 1950s, Japan began to build its self-defence forces and now has a powerful navy, a modern medium-sized air force that will soon fly the F-35 along with specially built F-15s, alongside more than 300 fighter aircraft and 50,000 personnel, and a growing land army and marine sea landing capability. Are these military assets “defensive” in nature? Partly, but aircraft carriers, high-speed destroyers, modern fighter aircraft and assault ships are surely as offensive as they are defensive. And Japanese Prime Minister Shinzo Abe has made it plain that in less than two years, he intends to seek to change the Japanese constitution to drastically curtail any obligation Japan has to maintain a purely defensive capability. In other words, he will ask the Japanese people and legislature to bless what Japan has already done. That could be more problematic than people realize. Like Germany, Japan suffered greatly in the Second World War. Virtually all its great cities were levelled either with atomic bombs (Hiroshima and Nagasaki) or fire raids that were carried out by giant B-29 bombers at low altitude at night. The attacks burned the heart out of Japan's cities. In March 1945, 100,000 people were killed in one night in a fire raid on Tokyo and many acres of the city were burned to the ground. Submarine blockades of Japan drastically curtailed food and fuel supplies. Hundreds of thousands of Japanese soldiers were killed either in the United States' march across the Pacific or in the Russian invasion of Manchuria near the end of the war. Japan was a prostrate nation by the end of 1945 and its ancient system of government was a shambles.
