The A2 design does not have windows. The heat generated by the hypersonic airflow over the body puts constraints on window design which would make them too heavy. One solution Reaction Engines proposed was to install flat panel displays, showing images of the scene outside. [1]
LAPCAT (Long-Term Advanced Propulsion Concepts and Technologies) was a 36-month European FP6 study to examine ways to produce engines for a Mach number 4-8 hypersonic flight aircraft. The project ended in April 2008. [1] It was funded by the European Commission research and development fund (rather than ESA), and cost 7 million euros. [2] [3]
Both these missions are funded by the US Defense Advanced Research Projects Agency to help develop hypersonic technologies and to demonstrate its effectiveness. [6] Under the original plan, HTV-1 was to feature a hypersonic lift-to-drag ratio of 2.5, increasing to 3.5-4 for the HTV-2 and 4-5 for the HTV-3. The actual lift-to-drag ratio of HTV-2 ...
A Chinese aerospace firm has completed the first test flight of a passenger plane that it claims can fly at Mach 4 – more than twice the speed of Concorde.. Beijing-based Space Transportation ...
A U.S. venture-capital firm recently led a round of seed investment for Hermeus Corp., a new startup looking to develop a hypersonic aircraft.Hermeus also announced its advisory board in a ...
Project Mayhem, the Air Force's secret new hypersonic bomber, is underway. Development on the bomber, which travels at Mach 10, just took a big step forward.
The second phase of the Hypersonic Weapon System development was to perform a set of flight tests with a series of boost-glide Hypersonic Technology Vehicles (HTVs). [12] HTV-1: a low performance hypersonic glider, originally planned to fly in September 2007, now canceled because it was found not possible to manufacture the leading edges. [13]
