Discussion Overview

The discussion centers around the testing and specifications of the DART AE 001, a hypersonic aircraft technology demonstrator. Participants explore details regarding its expected testing timeline, launch methods, and technical specifications, with a focus on the implications of hypersonic flight and the associated technologies.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • Some participants mention that testing for the DART AE 001 is expected to occur in 2024, but there is uncertainty regarding the specific timing and location of these tests.
  • Details about the DART AE's specifications are provided, including its length, weight, and potential speed capabilities, with a note that hypersonic flight is defined as speeds of Mach 5 or higher.
  • There is a question raised about the meaning of a "tow-launch" platform, prompting further exploration of its mechanics.
  • One participant proposes that a "tow-launch" platform involves towing the aircraft to altitude before release, comparing it to glider launches and noting the associated risks.

Areas of Agreement / Disagreement

Participants express uncertainty regarding the testing timeline and methods, indicating that multiple views exist on the specifics of the DART AE 001's launch strategy and the implications of using a tow-launch platform.

Contextual Notes

There are limitations in the discussion regarding the clarity of the testing schedule and the technical definitions of launch methods, which remain unresolved.

Supposedly, testing is happening this year. It's not clear though is they are talking about Summer in Australia (Jan-Feb (beginning of 2024) or Dec (end of 2024)), or in the US (June - Aug).

DART AE is a 9.8-foot-long (3 meters), 660-pound (300 kilograms) scramjet-powered technology demonstrator that can reach speeds of up to Mach 7, according to the company’s website. (Mach 1 is the speed of sound, which is about 767 mph, or 1,235 kph, at sea level. "Hypersonic" generally refers to flight that achieves speeds of Mach 5 or higher.)

The prototype test launch, powered by a guided Rocket Lab rocket, is scheduled for Quarter 1, 2025.

Does anybody know what a "tow-launch" platform is?
Fenix Space, Inc., located in San Bernardino, California, and Rocket Lab, located in Long Beach, California, have also been awarded DIU contracts for a reusable tow-launch platform
 
I think they mean towing it to altitude like a glider and then releasing it to fly freely.

It allows for a larger aircraft than dropping it from another plane like Stratolaunch and Roc, but it’s riskier.

Edit: yep, that’s exactly what they’re aiming for:
