Dunne D.8

The Dunne D.8 of 1912 was one of a series of tailless swept wing biplanes, designed by J. W. Dunne to have inherent stability. One of the few built was the only Dunne aircraft to fly, albeit very briefly, with the Royal Flying Corps (RFC). Others were used by the US Signal Corps and United States Navy and the short-lived Canadian Aviation Corps. It was the latter's first and only warplane.

Design and development

J. W. Dunne's first swept biplane wing aircraft, designed to have automatic stability, dated from his employment at the Balloon (later) Aircraft Factory at Farnborough during 1906–09. To preserve military secrecy testing was done at Blair Atholl in Scotland. After leaving Farnborough, Dunne set up a private company, the Blair-Atholl Syndicate Ltd. Its first aircraft was the Dunne D.5. When this crashed in 1911 it was rebuilt as the D.8. The two models shared very similar wings and the same engine, but the D.8 had a single pusher propeller instead of the chain-driven pair of the D.5. Their fuselages and undercarriages were also different.

D-10 tank gun

The D-10 is a Soviet 100 mm tank gun developed in late World War II. It originally equipped the SU-100 tank destroyers and was later selected for the T-55 tank, equipping these as late as 1979. On the T-55 the D-10 continues to be in active service in many countries.

History

At the beginning of 1944, the T-34 tank's F-34 76.2 mm tank gun was replaced by a more powerful 85 mm gun. This rendered the year-old SU-85 tank destroyer effectively obsolescent, since its D-5T 85 mm gun was now also fielded by a more flexible medium tank. F. F. Petrov's Design Bureau at Artillery Factory No. 9 was assigned the task of producing a 100 mm anti-tank gun that could be used on the SU-85 chassis, for the proposed SU-100. Petrov's team modified the S-34 naval gun for use in an armoured fighting vehicle.

The D-10 is a high-velocity gun of 100 mm bore diameter, with a barrel length of 53.5 calibres. Muzzle velocity of 895 m/s gave it good anti-tank performance by late-war standards. Initially it could penetrate about 149 mm of steel armor plate at 1,000 m range, superior to the German 75 mm KwK 42 mounted on the Panther tank and the Tiger I's 88 mm KwK 36 gun. Testing against Panther tanks at Kubinka, showed the D-10T could penetrate the Panther's glacis at its maximum range of 1500 m. This performance grew when APDS and more modern ammunition types were developed after the war. After the war a more effective high-explosive shell was also developed, taking advantage of the larger 100 mm bore.

List of songs composed by Franz Schubert

The following is a list of the complete secular vocal output composed by Franz Schubert (31 January 1797 – 19 November 1828).

It is divided into eleven sections, and attempts to reflect the most current information with regards to Schubert’s catalogue. The works contained in this list refer to those found primarily in the following two series of the Neue Schubert-Ausgabe (NSA) edition:

Note however that some of Schubert's song cycles contain both Lieder and part songs.
