Can you hear me now? At Mach 6 it matters

When a test flight lasts only minutes and ends in a fiery plunge into the ocean, you want to make sure the radios work – to ensure telemetry data is safely sent to the ground. So Boeing is testing the antennas for the US Air Force Research Laboratory’s X-51A Scramjet-Waverider hypersonic demonstrator in the anechoic […]

Blackswift breaks cover – DoD funds hypersonic aircraft

The Pentagon boffins have been keeping mum, but the DoD’s fiscal year 2009 budget request lifts the lid on Blackswift – DARPA’s prototype hypersonic aircraft. Formerly the Falcon HTV-3X, and being designed by Lockheed’s Skunk Works, the unmanned Blackswift is intended to take off conventionally on turbojet power, transition to scramjets, cruise at Mach 6 […]

Scramjet test a step towards DARPA’s hypersonic Falcon

Pratt & Whitney Rocketdyne has just tested a subscale combustor for a dual-mode ramjet/scramjet under the FACET programme to demonstrate a combined-cycle powerplant for DARPA’s planned Falcon HTV-3X hypersonic test vehicle. The combustor was ground-tested from Mach 2.5 to Mach 6.0. Lockheed Martin’s Skunk Works is designing the HTV-3X. As the attached video shows, the […]

Blackbird to Blackswift – via Falcon?

DARPA’s annual tech-fest has caused a stir in the blogosphere with the first appearance of a model of the HTV-3X demonstrator being designed by Lockheed Martin’s Skunk Works under the Falcon hypersonic technology programme. Bill Sweetman broke the story on AvWeek’s Ares blog, and Sharon Weinberger weighed in on Wired’s Danger Room. Hopefully Bill won’t […]

A short guide to hypersonics

Hy-what? Finding it hard to keep all those hypersonics programmes straight? After all, the US Air Force Research Laboratory’s Boeing X-51A waverider, powered by Pratt & Whitney Rocketdyne’s SJX61 scramjet, is the just latest in a long line. Here is a quick guide to the various recent and current research efforts aimed at air-breathing vehicles […]
