Stability Test Flight

Blue Dart Delta II experimental flight at Crooked Creek to confirm stability of the design and adequate motor sizing prior to commencing the Blue Dart Delta II rocket glider test program. This launch was successful and we’re ready to move on to the next phase of testing with the RC version.

The launch site video can be seen on our YouTube channel at this link.

The Blue Dart Delta II is a fiberglass rocket plane. 

Centre Section Spar

The Cozy MKIV centre section spar joins the wings to the fuselage. The center section spar is the heart of the wing structure.  The top of the spar is flat and the spar sweeps aft and the bottom has positive dihedral so that the fuel runs inboard while in level flight.

We did a trial fit of the spar with the fuselage and need to sand a few rough edges on the fuselage to get a better fit.

After a bit of sanding the spar rough fit into the fuselage.

The spar was moved back to the worktable and all outside surfaces were sanded.

Removed a small amount of foam from the outboard holes on the bottom of the spar. Mixed a small batch of dry micro and applied it to both holes to protect the foam.

Used the dremel tool to make a small flox corner around both outboard bulkheads CS5 & CS8.

Workshop temperature was 24 deg C and humidity 28%.

A batch of epoxy was mixed up and used to make up some micro as well as a small cup of flox.

Epoxy was brushed onto the existing glass edges of the outboard bulkheads then micro was applied to both bulkheads.

Next, the edges were filled with flox to make flox corners.

One layer of BID cloth was placed on each outboard bulkhead at 45 deg orientation and wetted out with epoxy. Lastly, peel ply was added to both layups.

Removed the peel ply from both outboard bulkheads.

Trimmed the glass edges and sanded the edges to be flush with the spar.

Sanded the inside centre section and vacuumed the inside of the spar.

About Yuri’s Night

Yuri’s Night is an annual event that typically has hundreds of parties around the globe (and beyond!) centered around April 12, the anniversary of the first human spaceflight and the first launch of the space shuttle. These events celebrate all that humanity brings with us as we explore the cosmos: music, art, science, culture, and each other! Local groups, science centers, museums, NGOs, and other non-profit groups independently produce events worldwide. We use space to bring the world together, to empower the greatest parts of who we are, and give vision to where we are going.

We look forward to post COVID when we can again host an in person annual Beyond Blue Aerospace Yuri’s Night event.
