MacDonald S-20

TerryLeave a comment

The S-20 utilizes all-metal construction but keeps it simple by the extensive use of pop rivets. It features open-cockpit seating for one, low wings and conventional tail-wheel landing gear. The fuselage is of steel-tube truss construction with a light alloy skin. The constant-chord wings are also covered with the same light alloy skin.

First flight was made on March 9, 1972 by N106AB. S-21 was the designation for plan-built aircraft by home-builders.

The cylinder heads are L-shaped combustion chambers allowing the valves to be actuated by direct contact with the cams eliminating rockers and rods.

The valves can be reground without removing the cylinders. The port pluga are unscrewed, and the valves can be removed through the ports.

Macchi M.B.320

TerryLeave a comment

The MB.320 is a development of the post-war MB.314. Powered by two Continental E.185 engines of 185 hp driving Piaggio mechanical variable pitch or Aeromatic automatic constant speed propellers.
The cantilever low-wing has a NACA 2300 section and wooden single-spar covered by plywood, fitted with differential slotted ailerons and flaps. The fuselage is built in three sections with a detachable metal e cone and woo centre and rear with plywood skins. The centre section contains the cabin and baggage compartments. The wood tail section has trim tabs in the starboard elevator and rudder. The undercarriage is retractable with the fully swivelling nose wheel retracting backwards into the nacelles.
Sound proofed and air conditioned, the cabin seats six, two pilots side-by-side, and four passengers. A baggage compartment is aft of the rear seats.

Introduced in 1949, the MB.320 was produced in limited numbers.

A manufacturing licence was acquired by Societe Francaise de Constructions Aeronautiques Lignel, which planned manufacture as the VEMA-51. This licence was not taken up.

In addition to various Italian commercial concerns, three were sold to East African Airways.

One of three supplied to East African Airways.

Macchi M.16

TerryLeave a comment

The Macchi M.16 was a light, single-seat aircraft designed by Alessandro Tonini and produced by Macchi in Italy in 1919.

It was a single-bay biplane with unstaggered wings and a largely conventional design except for an unusually deep fuselage that extended in a bulge below the lower wing. The landing gear axle being sprung directly on the bottom longerons with shock cord. The plane could also be fitted with pontoons.

The M.16 was developed in parallel with the Macchi M.20, a two-seat civil trainer aircraft which it resembled and with which it shared many common features.

The M.16 proved a successful sporting type, setting an altitude record of 3,770 m (12,370 ft) in 1920 while competing for the Coppa Mappelli (“Mapelli Cup”), and winning first prize in the competition in 1921.

The United States Navy purchased three float-equipped examples for evaluation as communication floatplanes.
