Blackburn Т.З Velos

В 1925 году фирма "Blackburn" на основе самолета Т.2 Dart разработала двухместную машину под требования ВМС Греции к патрульному самолету прибрежного действия. Главным отличием новой машины от Dart, помимо поплавкового шасси, стала установка оборудования для ночных полетов, усовершенствованной радиоаппаратуры и второй кабины для стрелка. Двухпоплавковый гидросамолет получил наименование Blackburn Т.3 Velos. В 1925 году фирма "Blackburn" построила небольшую партию таких машин, и в том же году началось их производство на основанном этой фирмой греческом национальном авиационном заводе. "Blackburn" получила все права на управление и владение заводом в течение пяти лет после его постройки. Первый Velos греческой сборки выполнил первый полет в марте 1926 года с колесным шасси, вторую машину собрали с поплавковым шасси. Всего в Греции построили 12 самолетов.
  Прототип Т.3А Velos, построенный в Англии, имел металлические поплавки (вместо деревянных). В 1927 году он совершил рекламное турне по Южной Америке, но заказов не последовало. Позже Т.3А переоборудовали в двухместный учебно-тренировочный самолет. Шесть таких машин закупила фирма "North Sea Aerial and General Transport Co. Ltd" для замены гидросамолетов Dart.
  В 1935 году самолеты Velos были сняты с эксплуатации, хотя последние машины утилизировали только в 1939 году.

A NEW BLACKBURN TORPEDO SEAPLANE
Foreign Attaches Witness Demonstrations of "Velos" at Brough

  ON October 28 last, a party of foreign Attaches and press representatives paid a visit to the air station at Brough at the invitation of the Blackburn Aeroplane Company and D. Napier & Sons, to see demonstration flights with a new seaplane torpedo carrier recently completed by the Blackburn works. The machine, which is known as the "Velos," retains all the familiar characteristics of the Blackburn "family," but it will be realised that it is a matter of some difficulty to design a twin-float seaplane with accommodation for a torpedo. Hitherto, torpedo-planes have mostly been of the land aeroplane type, with wheel undercarriage, but the advantages of the seaplane for the work are obvious. Thus, the machine is not compelled to return to a shore base, as would be a land machine, but can operate with a fleet, using a vessel as its supply base.
  The torpedo is carried immediately under the fuselage, the under part of which has been strengthened to take the splash from the torpedo as the latter strikes the water.
  From the flights, it was evident that the manoeuvrability of the "Velos," both on the water and in the air, is exceptionally good, and the machine appeared to leave the water (with full load) in about 20 seconds. The engine fitted is the famous Napier "Lion."
  The Blackburn "Velos" has a span of 48 ft., an overall length of 36 ft., and a height of 12 ft. 6 in. It carries a Mark VIII torpedo.
В отличие от Dart, Velos проектировался как двухпоплавковый гидроплан. Управляемость на воде у него была превосходная.

Although it has been written that T.12 made its maiden flight from Phaleron Bay on March 31, 1926, piloted by Col The Master of Sempill, the caption on the back of this photograph reads: “The 2nd Greek machine, Seaplane Torpedo Carrier, 5min before her first flight, Wed April 7, outside our factory”. The launch was not easy, there being no slipway, so the aircraft had to be launched from the beach by an inexperienced handling party. The Greek-built examples differed from those built in Britain in having built-up rear cockpits to raise the Scarff ring for the gun. Two were fitted with dual controls for use as trainers, and several were still in service as late as 1934.
Blackburns in Greece: Our photograph shows one of the five Blackburn "Velos" seaplanes recently tested by Major H. S. Travers, D.S.C., before delivery to the Greek Government. It is the production of the National Aircraft Factory near Athens, organised by the Blackburn Aeroplane Co., and is a development of the Blackburn "Dart" and "Swift" machines, being a 2-seater torpedo-carrying seaplane, fitted with a Napier "Lion."
The ladies enjoy a day beside the seaside watching the second KEA-produced Blackburn Velos, T.12, being hauled into Phaleron Bay in April 1926. Only one of the photographs bears a caption on the reverse; it is signed by “Wallace”, presumably the Blackburn employee who took the photographs.

The second product of the KEA factory was float-equipped T.12, seen here being manhandled from the factory to the shore of Phaleron Bay. Another ten examples of the Velos were built by the KEA for the Greek Navy, making a total of 12, in addition to four built in Britain. Note the distinctive maw of the Napier Lion installation.
The Blackburn Velos was a two-seat development of the company’s Dart torpedo-bomber, and was designed by Maj F.A. Bumpus in 1925 to a Greek naval requirement for a coastal-defence aircraft. Although the Velos was designed from the outset as a seaplane, the first of the Greek-produced examples, T.11, was fitted with a wheeled undercarriage and made its first flight from a rough airstrip behind the KEA factory on March 17, 1926. Interestingly, the floats on this example, seen at the KEA factory without its engine cowling, bear the marking T.11, suggesting that this is the first of the Greek machines after it had been fitted with a float undercarriage.
