The construction of Demo Myrsky continues

Suomeksi

The Tuesday Club began constructing the Demo Myrsky after the restoration work on the VL Myrsky II (MY-14) was completed. Demo Myrsky will be used to showcase the internal structures of the VL Myrsky II fighter, as it will not be fully covered. Demo Myrsky is built from the fuselage frame of the Myrsky MY-5 and the test wing, which was constructed at the start of the Myrsky restoration for testing the construction and assembly, and is now on display at the Finnish Aviation Museum.

During last year, the Demo Myrsky construction work gradually shifted from the Finnish Aviation Museum to the workshop rented by Aviation Museum Society on Puusepäntie. In this workshop, the Tuesday Club will continue its activities until the Finnish Aviation Museum has moved and begins operations in its new museum building. At Puusepäntie, the Demo Myrsky's horizontal stabilizer, elevator, and fuselage formers are under construction, and the damaged aluminum elevator is being repaired.

A jig was built for assembling the Demo Myrsky's horizontal stabilizer, and the assembly is now underway. The ribs have been attached to the front and rear spars in the jig. The stabilizer is already taking shape, awaiting the covering to be started.

Construction of the wooden rudder has begun, starting with the plywood ribs of the rudder. The construction of the formers, which are to be attached to the sides of the fuselage, has been completed and their installation onto the fuselage frame is about to commence.

It should be noted that the plywood blanks for the ribs were cut to shape, including the lightening holes, using a laser. The laser-cut plywood rib blanks were attached to a plate-like construction jig on the table, where the edge strips and vertical strips were glued onto the blanks. The finished ribs were coated for protection with nitrocellulose lacquer tinted with iron oxide.

The original but broken aluminium elevator we received has been repaired. As the elevator will be fitted to a static exhibit item, it is not being repaired to the standards required for an airworthy aircraft.

The fuselage frame from MY-5, which will be used in Demo Myrsky, was repaired and supplemented with missing parts at the Finnish Aviation Museum. Once the repair and supplementation work was completed, the fuselage frame was brought to Puusepäntie. There, the previously constructed vertical stabilizer and the wooden, plywood-covered upper covering, which fits between the cockpit and tail, were assembled. Both items have been covered only on one side, so their internal structure remains visible. Numerous metal clamps to be attached to the fuselage have been manufactured. These were painted with grey Isotrol paint. Bearing mounts were made for the rudder bearings, enabling the bearings to be fitted into place.
