138. Wing Storage

05/10/2014

We have a cunning plan for storing and moving the aircraft when it’s finished. Unlike most WWI aircraft, it’s small enough with the wings and elevators removed to fit in a road-legal trailer, and while rigging and de-rigging isn’t completely straightforwards, it’s very far from impossible either.

The base of the trailer was used to get the fuselage to the LAA Rally, and Keith, our trailer-builder, is incorporating a couple of changes in that before starting on the box on the top.

The plan is that the fuselage will be towed tail-first, enabling the trailer to have a fairly low front, sloping upwards towards the rear where the cabane and propeller will be. The rear door will swing down and form a ramp for getting the fuselage in and out, and bottom-hinged side doors will carry the wings in racks, ready to be lifted out and mounted on the aircraft when the doors are opened.

I started work on the racks last week, and what was originally planned to take about a day actually took nearly a week. Still, it’s done now, and you can see more or less how they work from these pictures.

An 8ft x 4ft sheet of OSB has two 4in x 2in timbers screwed to it.

At the inboard end (towards the rear of the trailer) the spar ends are bolted to the 4 x 2 with spacers to ensure sufficient clearance between them. The leading edges of both wings sit on carpeted supports at both ends.

At the outboard end the strut fittings are connected by short pieces of timber, and the top surface of the top wing is clamped to the carpeted 4 x 2, with a beam which fits over the bottom wing strut fittings and is screwed down with M8 threaded rod.
