There's tons of new updates regarding Avro Museum and the Arrow II Project to read about in this quarter's newsletter.
Avro/Orenda Employee List Update
The Museum is maintaining an updated listing of Avro/Orenda employees on our website. To date, this task has been undertaken using scraps of employee information and miscellaneous corporate and trade magazine announcements. If you know of someone who worked for one of these companies and whose name should be on the listing, please forward their name, company affiliation, position and years employed to the Museum e-mail address.
Arrow II Project
The Arrow II project is progressing quite well. In late June, the Museum re-applied to the Community Facility Enhancement Program for a matching funds grant to complete the purchase of the hangar we occupy at Springbank Airport.
In August, the wing structure, made up of the ribs and spars which had been permanently bonded together earlier in the year, was separated from the fuselage and raised up into the hangar ceiling. This has allowed the team of volunteers to cut a series of wing support jigs that match the contour of the underside of the delta wing. The jigs are now being assembled into a large structure on the hangar floor that will be precisely levelled and aligned. Following this, the underside wing skins will be placed on the jig and the wing skeleton lowered into place. The foam-board side of the wing skin will then be marked where the spars and ribs are aligned.
Once completed, the wing skins will be removed and the points of contact with the ribs and spars, as shown by the markings on the foam backing, will have the foam board substrate routed out so as to allow the final preparation of the bonding surfaces. This task will take many weeks to complete. In the interim, the wing skeleton will receive a final trimming and sanding on the underside. Also, pressure equalization ports will be drilled through the ribs and spars and moisture drainage holes positioned to ensure there is no build-up of moisture within the finished wing during future operation of the aircraft.
Once the wing structure was disconnected from the fuselage, two dollies were constructed which would allow the fuselage to be placed on its side and moved outside the hangar for surface finishing. The remaining central panel on the underside along with two hatches for storage and battery compartments will be prepared and installed. Final surface covering and sanding of the underside of the fuselage is expected to be completed before winter weather precludes outdoor work.
The fuel tanks will be fabricated from foam board covered with epoxy, fibre glass and fuel sealants. Several small test tanks were constructed in 2008 and filled with jet fuel to test the viability of this construction method. No fuel has leaked from these test tanks. A 1/3 scale mockup of the four fuel tanks was completed a year ago. Since that time, the detailed drawings have been completed and the foam board sheets prepared for cutting the component parts. This is now underway and assembly of the tanks will be starting in the near future.
Our Arrow II project is progressing nicely, the spars are in place and connected and the first of the wing ribs have been fit and tacked in place. We’re looking forward to easier progress now that the wing’s basic frame is established. The next step will be molds for the wing skins and the fabrication of fuel tanks.
