Gloster Grebe

Одноместный истребитель Grebe наряду с Hawker Woodcock и Armstrong Whitworth Siskin являлся истребителем, который рассматривался для обновления в межвоенный период парка британских ВВС. Самолет был спроектирован на базе опытного биплана Grouse. Потенциал данной машины был настолько высок, что Министерство авиации провело его оценочные испытания. По весьма обнадеживающим результатам этих испытаний были заказаны три прототипа. Первым стал прототип Grebe, который получил обозначение Grebe Mk I. Машина оснащалась одним двигателем Armstrong Siddeley Jaguar III мощностью 325 л.с. После оценочных испытаний данного прототипа тут же был выдан заказ на запуск в серию самолета на базе второго прототипа Grebe Mk II, в конструкцию которого внедрили ряд усовершенствований, включая шасси с управляемым хвостовым костылем и более мощный двигатель Jaguar IV.
  Королевские ВВС Великобритании получили около 120 экземпляров Grebe Mk II, среди которых были двухместные тренировочные самолеты с двойным управлением Grebe (Dual). Первый самолет был передан в строевую часть в октябре 1923 года. Самолет оставался на вооружении строевых частей британских ВВС почти пять лет, за это время некоторые машины приняли участие в программах испытательных полетов. Например, Grebe Mk II стал первым истребителем британских ВВС, достигшим максимальной скорости в 386 км/ч, а еще два самолета данного типа со специальными приспособлениями на верхнем крыле привлекались к экспериментальным запускам в воздухе с британского дирижабля R33. В 1928 году три самолета Grebe были приобретены Новой Зеландией и поставлены в национальные ВВС.

THE MACHINES

Gloucestershire Aircraft Company, Ltd., Cheltenham

  THE Gloucestershire Aircraft Company, the constructors of the world-famous "Mars I," or "Bamel" racing machine, which holds the British speed record of 196-6 m.p.h., have two types of machines at Gothenburg, one on view in the exhibition itself, and the other giving actual flying demonstrations. Both machines are of recent design, for which Mr. H. P. Folland, who also designed the "Mars I," is responsible, and, as may be expected, possess several distinctive features.
<...>
  The second machine, the "Grebe," which will be flying during the exhibition, has been designed as a high altitude fighting scout, embodying the special arrangement of high lift and medium lift wing sections, as in the "Grouse."
  Having been designed at the request of the British Air Ministry it is not permitted to give full details, but it may be said that on actual flight trials the machine shows good improvement in performance at altitude, and, whilst having greater loading-carrying capacity, its manoeuvrability and general handling is a considerable improvement.
  Amongst detail improvements the petrol system may be mentioned as being simplicity itself and quite fool-proof, and the tanks being mounted in the wings gives greater immunity from fire.
  The general dimensions are :- Span, 29 ft.; length, 19 ft.; height, 9 ft.
  The engine fitted is a 350 h.p. Siddeley "Jaguar."
Gloster Grebe был спроектирован Генри Фолландом на основе опытного самолета Grouse, также в новой машине заметно влияние и спроектированного им же SE.5. На рисунке - Grebe Mk II из британской 25-й эскадрильи.

"LIGHTER-HEAVIER-THAN-AIR": A close-up of the R.33 (or part of same) and the two Gloster "Grebes." Each of the latter weighed over a ton, and were successfully launched from about 2,000 ft.
R.33 AS AIRCRAFT CARRIER: Two detail views showing the suspension of the Gloster "Grebes" from the airship's keel. Each machine was suspended by a central quick-release attachment to the top plane centre section, whilst three struts, two to the wings and one to the fuselage near the tail, served to prevent the machine oscillating. Note the flexible piping running from the keel to the side of the fuselage, which conveyed the mixture from the Bristol "Gas" starter (in airship) to the "Grebe's "Jaguar" engine.
"DROPPING THE PILOT" - NEW STYLE: One of the two Gloster "Grebes" carried by R.33 gets well away during the tests at Pulham last Thursday. Piloted by F/O Mackenzie-Richards, the "Grebe" fell about 100 ft. before complete control was obtained, when, opening out his engine - note the "prrrup" of smoke - the pilot made a half-roll and then flew away.
The first production Grebe II, this type entering RAF service in October 1923 and remaining first-line equipment until mid-1928.
The Gloster "Grebe" II (Armstrong Siddeley "Jaguar") For a long period one of the most popular single-seater fighters in the Royal Air Force, the Gloster "Grebe," is now being gradually superseded by a later type, the Gloster "Gamecock," but it is still being used in large numbers. It has a fairly thick section, high-lift top plane and a thin-section, high-speed lower plane. It is claimed that at top speed the upper wing carries nearly the whole load, so that monoplane efficiency is approached. The "Grebe" is used by the following squadrons: No. 19 (Fighter), Duxford; No. 25 (Fighter), Hawkinge; No. 29 (Fighter), Duxford; No. 32 (Fighter), Kenley; and No. 56 (Fighter), Biggin Hill.

"AFTER YOU WITH THAT TANK!" One of the most thrilling events seen at this year's R.A.F. Display at Hendon was the demonstration of Low Bombing by three Gloucestershire "Grebes" from No. 25 Fighter Squadron, and three Siddeley "Siskins" from No.41 Fighter Squadron. Instead of the machines diving on to their target - a stranded Tank - one after another from the same direction, they maintained a continuous attack, swooping down in rapid succession from all directions, with, apparently, only a matter of yards separating each machine, and releasing their bombs from about 50 ft. without the use of bombsights or such-like gadgets. The picture by Charles Dickson, gives one an excellent impression of this wonderful "criss-crossing" manoeuvre by the machines.
SOME "GLOSTER" CONSTRUCTIONAL DETAILS: 1 shows the tail-plane support and elevator crank as well as fittings for the stern-post, etc., of the "Grebe." In 2 are seen the gravity petrol tanks, mounted in the top plane, the petrol cocks being within reach of the pilot from his cockpit. The fuel flows to a distributor (shown last week) which enables fuel to be taken from either or both tanks. The ailerons of the Gloster "Grebe'' and "Grouse" are operated, as regards the lower flaps, by a crank of the form shown in 3, which is mounted on a specially strengthened rib, and from which tie rods run to the controls, while a steel tube runs to the aileron crank, as shown in 4. The movement is transmitted to the top ailerons by struts, the attachment for which is shown inset in 4.
