This launch tower will be raised in only 40 days! Don't miss the rocket launch on 16th of July 🚀
☀ Good morning fellow rocket enthusiasts! Another day, another launch attempt. Let's hope the weather is in our favor today 🙏 #StratosIII
The tower is now being raised and we are ready for the countdown. T-6:53 hours remaining 🕒
We are still planning to launch. We just vented to our final fill mass. Please Stand by!
Apperently the video posted by catdlr shouldn't have been made public. It showed a small KNDX rocket motor test. Also the Stratos advanture continues with Stratos IV, planned for launch in 2019.

Based on the capabilities and potential of the Stratos III design, Stratos IV was developed and builts on DARE's hybrid rocket technology. The vehicle features active roll stabilization and the most powerful student-built hybrid engine in the world, we a peak thrust of 25 kN. The design is recently revealed, and the vehicle is currently under construction for its space shot in August 2019.
dare welcome on NSF. Are you related to the DARE society?I found this Delta (TU Delft) Article: https://www.delta.tudelft.nl/article/dare-rocket-team-shoots-spaceLaunch from the Denel Overberg test rangein South Africa.AFAIK Dare is building two rockets for their Stratos IV launch mission. They are developed from Stratos III, the titanium nozzle was already developed for Stratos III but it wasn't ready in time. Dare will use it on Stratos IV.Are you taking the NLR flight computer as payload again?
Very good job by also replacing the aluminium combustion chamber by a composite one.I've four questions concerning the composite combustion chamber:1) Are you using carbon-fiber or glas-fiber for the chamber. 2) DARE has experience with glass-fiber, do you also have experience with carbon fiber casings?3) Is the solid six (or alumini) involved with the composite casing development or is it part of StratosIV.Lastly 4) are further static tests planned to prove the composite casing together with the titanium nozzle?Another question came to mind: are you using the same oxidizer injection system as on stratos III?Or did you have to change it for the composite combustion chamber.Thanks for the info. I'll anxiously wait for more detail about the payload. Is there another croudfunding planned?
the current plan is indeed to launch from the Denel Overberg Test Range.
On April 22nd, Project Sparrow performed a successful two-second test of the DLX-150A Firebolt, DARE's first functional liquid-fuel rocket engine prototype, running on a mixture of Ethanol-LOx, with a design thrust of 15kN.The goal of the test was to validate the injector design and ignition sequence. The engine tested was a lower chamber pressure variant, and reached an average thrust of 11kN at a chamber pressure of 40 bar.
In July 2022, Project Sparrow performed another successful two-second test of the DLX-150A Firebolt, DARE's first functional liquid-fuel rocket engine prototype, running on a mixture of Ethanol-LOx, with a design thrust of 15kN.The goal of the test was to validate the injector design and ignition sequence. The test targeted a chamber pressure of 30 bar, producing around 9kN of thrust.
The Project Sparrow team recently closed its chapter on the development of a technology demonstrator for a reusable liquid rocket engine with great success. For over two years, the team has worked on the reusable DLX-150B 'Firebolt' Liquid Rocket Engine, performing cold-flow tests, perfecting injector design and ignition sequence and performing a total of 30 seconds of burn time with a reused engine. With the engine up and running, DARE is presented with a great opportunity to take on the next step. Introducing Stratos V, DARE's new flagship project. Our mission is to develop, launch and fully recover a technology demonstrator for a reusable rocket based on the liquid rocket engine developed and tested by the engineers of Project Sparrow.
Project Sparrow developed the DLX-150 'Firebolt‘ liquid bi-propellant engine and tested it many times. In this video, seven hot fire tests conducted over the last two years are shown in chronological order, with the engine reaching a total burn time of over 30 seconds at full flow. We are excited to design a rocket based on this incredible liquid propellant engine. Stay tuned for more!
During the weeks leading up to the SPEAR launch campaign, team members will present a part that they worked on and explain their function and any encountered challenges. Get to know the SPEAR vehicle before its flight!The fourth video, by Wim Jodehl, is on the Drogue Parachute Deployment Device (DPDD) system of SPEAR.
In September 2022, Project Sparrow performed its fourth and last hot fire test of the regeneratively-cooled DLX-150B engine. The 3D-printed Ethanol-LOx engine ran at a reduced chamber pressure of 30 bar for 6.5 seconds, producing a steady 9 kN of thrust. Further testing of the engine will be carried out over the course of project Stratos V.
