[Na Caixa] Avro Anson Mk1 - Airfix - 1:72

[Eduardo_Correa]

Participando de mais um GT, desta vez com um kit antigo do Avro Anson. Esse bimotor inglês foi desenvolvido inicialmente como aeronave de reconhecimento marítimo sendo bastante empregado pelo Coastal Command quando do início da WWII. Já no início do conflito se mostrou obsoleto, sendo retirado da linha de frente. Permaneceu porém em serviço como avião de transporte, ligação e também como treinador de aeronaves multimotoras e de navegação, sendo que nesta função podia levar diversos alunos ao mesmo tempo.

The Avro Anson is a British twin-engined, multi-role aircraft built by the aircraft manufacturer Avro. Large numbers of the type served in a variety of roles for the Royal Air Force (RAF), Fleet Air Arm (FAA), Royal Canadian Air Force (RCAF) and numerous other air forces before, during, and after the Second World War.

Avro 652
Initially known as the Avro 652A, the Anson was developed during the mid-1930s from the earlier Avro 652 airliner in response to a request for tenders issued by the British Air Ministry for a maritime reconnaissance aircraft. Having suitably impressed the Ministry, a single prototype was ordered, which conducted its maiden flight on 24 March 1935. Following an evaluation in which the Type 652A bettered the competing de Havilland DH.89, it was selected as the winner, leading to Air Ministry Specification 18/35 being written around the type and an initial order for 174 aircraft being ordered in July 1935. The Type 652A was promptly named after British Admiral George Anson.

The type was placed into service with the Royal Air Force (RAF) and was initially used in the envisioned maritime reconnaissance operation alongside the larger flying boats. However, by the outbreak of the Second World War, the Anson was soon found to have become obsolete in front line combat roles. However, large numbers of the type were put to use as a multi-engined aircrew trainer, having been found to be suitable for the role, and became the mainstay of the British Commonwealth Air Training Plan. The type continued to be used in this role throughout and after the conflict, remaining in RAF service as a trainer and communications aircraft until 28 June 1968.

During the post-war climate, the Anson was increasingly produced for the civil market, being used as a light transport and executive aircraft. By the end of production in 1952, a total of 8,138 Ansons had been constructed by Avro in nine variants; in addition, a further 2,882 aircraft were manufactured by Federal Aircraft Ltd in Canada from 1941. By the 21st century, the vast majority of Ansons had been retired from flying. However, a single Anson Mk.I, which had been originally manufactured during 1943, had been restored to airworthiness, having been refitted with later metal wings. On 18 July 2012, this restored aircraft performed its first flight.

Development
Edit

In 1933, the British Air Ministry proposed that the Royal Air Force (RAF) acquire a relatively cheap landplane for coastal maritime reconnaissance duties; the proposed aircraft would perform as a supplement to the more capable, but expensive, flying boats which the RAF had adopted for conducting maritime reconnaissance missions. The Air Ministry requested tenders from major aircraft manufacturers to produce a suitable aircraft in order to meet this requirement. Avro decided to respond to the request with the Avro 652A, which was a modified version of the earlier Avro 652, a twin-engined, six-seat monoplane airliner. After evaluating the various submissions received, the Air Ministry decided to place a pair of orders, with Avro and de Havilland respectively, to manufacture single examples of the Type 652A and the de Havilland DH.89 for evaluation purposes in order to meet this requirement late in 1934; an evaluation and the subsequent selection of a design for production to take place by May 1935.[1][2]

On 24 March 1935, the Avro 652A conducted its maiden flight at Woodford Aerodrome, Greater Manchester. Between 11 and 17 May 1935, the prototype participated in a formal evaluation against the competing DH.89M by the RAF's Coastal Defence Development Unit at RAF Gosport, Hampshire. During these trials, the Avro aircraft proved to be superior and was accordingly selected as the winner of the competition on 25 May 1935.[3] In response to its selection, Air Ministry Specification 18/35 was written around the Type 652A; in July 1935, an initial order for 174 aircraft, which had been given the name "Anson", was received.[4]

On 31 December 1935, the first production Anson performed its maiden flight; changes from the prototype included an enlarged horizonal tailplane and reduced Elevator span in order to improve stability. Additionally, while the prototype had not been fitted with flaps, production aircraft could accommodate their installation from the onset to increase the viable glide angle and reduce landing speed.[5] On 6 March 1936, deliveries to the RAF commenced.[6] By the end of production in 1952, a total of 11,020 Ansons had been completed, which made it the second most numerous (after the Vickers Wellington) British multi-engined aircraft of the Second World War.[7]

Design
Edit

The Avro Anson was a twin-engine, low-wing cantilever monoplane. Developed as a general reconnaissance aircraft, it possessed many features that lent itself to the role, including considerable load-carrying ability, and long range.[8] The structure of the Anson was relatively straightforward and uncomplicated, relying on proven methods and robust construction to produce an airframe that minimised maintenance requirements.[8] Much of the internal structure had retained similar to the earlier Avro 652 airliner from which it had been developed. The Anson Mk I was furnished with a low-mounted one-piece wooden wing, composed of a combination of plywood and spruce throughout the wingbox and ribs. The fuselage was composed of a welded steel tubing framework which was principally clad in fabric; the exterior of the nose was clad in magnesium alloy.[8]

The Anson was powered by a pair of Armstrong Siddeley Cheetah IX seven-cylinder air-cooled radial engines, which were each rated at 350 horsepower (260 kW).[9][5] Each engine was provided with its own duplicated fuel pumps and separate fuel and oil tanks; the tanks were composed of welded aluminium and mounted in cradles housed within the wing. The engine cowling were intentionally designed to have a reduced diameter in order to reduce their negative impact upon external visibility, which was considered to be valuable to the type's reconnaissance function.[8] These engines each drove a set of two-bladed Fairey-built metal propellers.[5]

The Anson was equipped with a retractable undercarriage arrangement, which was uncommon upon its introduction; it holds the distinction of being the first aircraft to feature such an innovation to enter service with the RAF.[8][10] While the main undercarriage was retracted into recesses set into the bottom of the engine nacelles, the tail wheel was fixed in position. Commonly, the undercarriage was fitted with Dunlop-built wheels, tyres and pneumatic brakes and Turner legs.[5] The retractable undercarriage was mechanically operated by hand; in which a total of 144 turns of a crank handle, situated besides the pilot's seat, was necessitated.[11][12] To forgo this laborious process, early aircraft would often perform short flights with the landing gear remaining extended throughout, which would reduce the aircraft's cruising speed by 30 mph (50 km/h).[7]

Initially, the Anson was flown with a three-man crew, which comprised a pilot, a navigator/bomb-aimer and a radio operator/gunner, when it was used in the maritime reconnaissance role;[13] from 1938 onwards, it was typically operated by a four-man crew.[14] The bomb-aimer would perform his function from a prone position in the forward section of the nose, which was provisioned with a bombsight, driftsight, and other appropriate instrumentation, including a landing light. The pilot was located in a cockpit behind the bomb-aimer's position and was provided with a variety of contemporary instrumentation, including those to enable flight under instrument flight rules (IFR) and indirect instrument lighting for night flying purposes.[15]

Immediately behind the pilot's position is a small folding seat fixed to the starboard side of the fuselage for an additional crew member or passenger, along with racks that would contain a pair of parachute packs that would be clipped onto the harnesses worn by both the pilot and the navigator. Behind these is the navigator's station, a chair and table provisioned with navigational aids such as compasses, Bigsworth chart boards, sea markers, calculators for course, wind and speed, a signalling lamp and float flares.[13] Aft of the rear spar is the wireless operator's station, this being a table furnished with contemporary wireless apparatus of the era, including a winch for the trailing aerial, which was attached to the upper fuselage immediately behind the aircraft's cockpit.[13]

The defensive armaments of the Anson consisted of a single .303 in (7.7 mm) Vickers machine gun which was fixed within the forward fuselage and aimed by the pilot, while an Armstrong Whitworth-built manually operated gun turret located on the Anson's dorsal section was fitted with a single Lewis gun.[13] Additionally, up to 360 pounds (160 kg) of bombs, which could consist of a maximum of two 100 pounds (45 kg) and eight 20 pounds (9 kg) bombs, could be carried in the aircraft's wings.[16] Those Ansons that were used in the training role were outfitted with dual controls and usually had the gun turret removed, although specific aircraft used for gunnery training were fitted with a Bristol hydraulically operated gun turret, similar to that used in the Bristol Blenheim.[17][18] The tail fairing of the starboard nacelle contains an inflatable dinghy which is provided with automatic actuators and marine distress beacons.[13]

À propósito, o título do tópico está "Abro" ao invés de Avro.

Trabalhos iniciados.

Por se tratara-se um kit bem simples e bem goiaboso, não esperem muita coisa.

Cockpit muito simples, resolvi criar coragem e fazer algo a mais. Nada muito extravagante... uma caixa de primeiros socorros e um pedal de rudder, feito com um pequeno pedaço de arame e sprue. Contos não coloquei pois vou por a tripulação.


Logo de cara já tem que mascarar...


Essas janelas laterais deram um trabalho danado para ficarem no lugar... forma muito ruim...

Como se trata de um avião escola de navegação e comunicação, onde os alunos vão atrás, fiz um pequeno mapa e tentei fazer um lápis com cavaco de palito...

O aluno de trás opera um rádio. Tentei criar um painel com canetinha hidrocor

Aqui as asas, que obrigatoriamente são fechadas já com o trem de pouso instalado.
