SDSU Icarus 2 Boosted Dart Launch

Some great footage of the SDSU Rocket Project Icarus 2 rocket from back in December 2017. Icarus 2 is a boosted dart rocket, where after burnout and separation, the dart coasts to apogee.

The specs of the flight were,

  • Launched at FAR on one of their rails.
  • CTI L2200G reloadable booster
  • Fiberglass and aluminum transition cone
  • Fiberglass body with brass nosecone and tailcone and ss fins. 4.9 lb total weight
  • 6’2″ tall assembled
  • 27,148′ apogee
  • Mach 1.95
  • ~Mach 1 @ ~25,000 when shockwave reached pressure tap holes and triggered Telemetrum to deploy apogee charge.
  • Booster (- transition cone) recovered. Parachute epoxy failed and cone floated away into the hills of the Mojave.
  • Dart fully recovered with parachute deployed but reefed and shredded by sharp tail fins.

Boosted darts are not new, in the 50s the Loki-dart was used as a sounding rocket and reached a max altitude of 55km. In 1996, the Reaction Research Society successfully flew their own boosted dart rocket to 80km, there is a great article on the project here and is worth a read for any rocketry enthusiast.

The March newsletter is out from the SDSU Rocket Project, detailing the plans ahead of the FAR MARS competition, recent engine testing and future planned hot-fire testing.

The team have been building a LOX/Methane regen engine, so will worth a look and follow!

SDSU Rocket Project Second LOX/LCH4 Test

Video Caption: On March 3rd, 2018, the SDSU Rocket Project had their second static hot fire of a LOX/LCH4 Engine designed towards the FAR/Mars Launch Contest. This upload contains the compiled footage of all engine burn videos during Static Hot Fire B.

SDSU Rocket Project LOX/LCH4 Testing Footage

As reported earlier the SDSU Rocket Project had a successful test of their LOX/LCH4 rocket engine, below is newly uploaded footage of the test that happened just over a week ago.

Sounds like there may have been some combustion instability? Interested to hear your thoughts, leave a comment below.

It Was a LOX/LCH4 Engine Testing Kinda Weekend

Well, what a weekend it has been, both Purdue SEDS and the SDSU Rocket Project conducted successful tests of their own respective LOX/LCH4 rocket engines or methalox engines as they are sometimes called.

Both teams intend to fly these rocket engines in the FAR-MARS prize in May and therefore are eligible to win up to $100k of prize money!

Awesome work being done by both and great to see liquid methane being given a go by student teams.

We have ignition!

Team Icarus Launch Boosted Dart to 27,148ft

From Facebook

“Data is in from the recovered dart on Icarus 2! Separation speed was Mach 1.9, peak acceleration was 34.4 G’s, and it achieved a maximum altitude of 27,148’. This makes Icarus 2 the fastest and highest flying rocket in SDSU history.

The peak altitude was lower than expected because an anomalous pressure spike in the avionics bay resulted in an early apogee detection and parachute deployment. We are working to find the source of the pressure spike. The team has learned a tremendous amount about the operation, manufacturing, and flight dynamics of boosted darts from this project. The experience and data gained will go a long way towards supporting future high altitude attempts.”
