Aim
- Profile 7, 550 mph.
Set-up
- Track 17, Km 0.5.
- 17C, 923 mb, sunny. Wind calm.
- Fuel full.
Run Details
- 0700 local. Slick start team work with the AST, good engine start at 49 sec, total engine running 10 min.
- Reheat accel to 562 mph peak. Car felt very stable in the absence of any crosswind.
- Dust build on the canopy, both inside and out, was a major problem with visibility only just good enough to continue. No obvious dust leaks into the cockpit.
- Some vibration felt through the suspension at around 500 mph, which appears to be due to the slightly ‘bubbly’ surface just south of the causeway.
- Chute at 520 mph, solid jolt as it deployed, followed by a slight pull to the left which was easily controlled. Chute deployment bag was double-tied with 150 lb line, still suffering from canopy dump, but deployment effective.
- Brakes on at 200 mph, 40-45 Bar. L brake 240C,
- Stop at Km 11 (2.7 DTG), as planned.
- AMAD peak 70C.
Summary
A successful 550+ mph run and chute deployment. Without any wind, the Car runs on rails.
Procedural Points
- Slick team effort, no points.
Technical Points
- Dust on the canopy needs further work.
- Chute canopy dump is not impairing the deployment, so we can probably continue to use the current arrangement in order to complete the high-speed test programme.
