On his return to Australia, concerned at the lack of manufacturing capabilities there and at the possibility of aircraft not being available from 'traditional' i. British sources during wartime, he commenced a lobbying campaign to convince the Australian Government to establish a modern aircraft industry. The government required little persuasion and encouraged negotiations between a number of Australian companies.

The outcome of these negotiations, begun in Augustwas the formation of CAC the following year. By September a factory had been completed at Port Melbourne. This led to Lawrence Wackett joining the company; he immediately became the General Manager.

It is almost entirely due to Wackett's efforts that the Wirraway became the first aircraft produced by CAC. In Wackett had led a technical mission to Europe and the United States to evaluate modern aircraft types and select a type suitable to Australia's needs and within Australia's capabitities to build.

With its first aircraft type the company thus became one of very few in the world that have produced an aircraft fitted with engines and propellers made by the same company see also de Havilland.

While CAC largely produced Australian versions of foreign aircraft, it also developed a number of original designs during and after the Second World War. These indigenous designs include the Wackettwhich was only the second type produced by the company. The Wackett was a simple trainer aircraft, but later designs during World War II were the sophisticated Woomera and CAhowever these types were destined to fly only in prototype form. Other, jet-powered aircraft designs in the s and s did not even leave the drawing board, however in CAC was given the go-ahead to design and manufacture a version of the F Sabre with a revised engine and armament.

The Sabre was developed and produced concurrently with the indigenous Winjeel trainer, with Sabre manufacture coming to an end in In CAC commenced licence production of a version of the Aermacchi MB optimised for Australian conditions, this programme ended in In CAC joined the small number of aircraft manufacturers which have built both fixed- and rotary-winged aircraft, when it began production of a variant of the Bell Kiowa for the Australian Army and Royal Australian Navythe last of these was delivered in This company was purchased by Boeing Australia in These aircraft included the:.

The Kiowa was the last type built by CAC. The company was part of the Australian Aircraft Consortium which designed the A10 Wamirabut this programme was cancelled in shortly after the prototype was completed. During its existence the Commonwealth Aircraft Corporation produced over aircraft of all types, including prototypes and aircraft assembled locally from imported components.

Of these, almost were examples of aircraft types wholly designed by the company. The designations used by CAC reflected production or design work in fulfillment of different in-house projects or government contracts rather than different types produced for instance the different designations for the Wackett and Winjeel prototypes compared to their production versions. Construction numbers to appear not to have been assigned. The list of company designations and construction numbers is:.

As already noted, CAC produced aircraft engines under licence. It also designed the R Cicada which was intended to be used in the Winjeel. Because of its lower cubic capacity the Cicada was more complex and thus significantly heavier than the R and also had higher fuel consumption.

Only two development examples of the Cicada were ever built, one of which was actually fitted to Winjeel prototype RAAF serial A The two engines accumulated about hours before the programme was terminated in September An engine upgrade can breath new life into an aging airframe or transform the performance of an underpowered one.

More Questions?The Cascade Pressure Cowl is a ram air intake system for select turbine engine installations. It has been independently tested to deliver significantly more air than any other intake system in the agricultural aircraft industry. After side panels are off, it takes less than two minutes to remove the filter assembly.

Design of the inlet and air delivery system improves serviceability over factory with ample room to access the filter box, fuel nozzles, and fwd chip detector, reducing maintenance time. Increased air volume to the turbine reduces ITT. This temperature reduction reduces the long term wear that results from high heat and thermal cycling.

Q: How does the pressure cowl affect longevity of the engine? Q: what is the installation time? Q: how is the stc delivered?After going through the list, I felt a little blighted by history — Australia has designed some amazing-looking aircraft.

The best example of this now lives in a shed in suburban Melbourne. In the Australian National Aviation Museum at Moorabbin Airport in Victoriathere lies the mock-up of the best-looking aircraft ever designed by an Australian.

You could probably build your own with a trip to Bunnings and a spare Saturday afternoon. Its origins go back to the early s, when the RAAF hierarchy perceived a coming problem with its pilot training model. Both types possessed a blistering performance that would require a modern training pipeline to produce qualified pilots to fly them.

Ab initio candidates would conduct their training entirely on the the Macchi before converting to their operational type. That leap from the Macchi to fast jets led the RAAF to believe a Lead-In Fighter was needed — an aircraft that would take young pilots from the straight-wing subsonic Macchi towards a mach-two delta like the Mirage or FC.

It was optimised to be small, light and cheap — but at the same time, offer high performance that could prepare pilots for the world of fast jets. Here, the numbers get a little fuzzy: It had an empty weight of lbs just shy of three tonnesand gross weight of lbs. The designers went for the Rolls-Royce Adour turbofan at time, being built for the Sepecat Jaguar, and today, powering the BAe Hawk which promised lbs of dry thust and lbs with reheat.

Top speed for the CA was intended to be Mach 1. Now, bear those figures in mind when you consider how small the CA was. Total length: 37ft, 8. Height: 10ft, 9. The span on the delta wing? For the Anglophiles, the Folland Gnat had a wingspan of 22ft; length of 28ft, and an empty weight of lbs. The Gnat was powered by a Bristol Siddeley Orpheus producing lbs of thrust.

Both the Skyhawk and Gnat could get up to just below Mach 1. While the CA was intended to be a Lead-In Fighter trainer, any guns would have had to have been carried externally.Your account is blocked.

Outboard weapon.It was originally planned to be powered by two Rolls-Royce Tay engines; the final version was however designed for the more powerful Rolls-Royce Avon turbojet engines.

The aircraft was to be fitted with the most up to date radar and electronic equipment. Its anticipated performance was to be in the region of Mach 1. Over the life of the project dozens of mock-up models were made at different scales, with hundreds of detailed drawings, plus wind tunnel tests proving the delta wing was more than satisfactory.

The program was described by the British visiting CAC at the time as "the company's project was a most ambitious design for a fighter and as advanced as anything yet seen in any other part of the world. The testing results were so promising and ground breaking for a delta wing design that the Royal Aircraft Establishment requested permission to distribute the results to the major UK aircraft manufacturers and Avro Canada.

The decision to cancel the CAC CA project was controversial at the time among the Australian political elite and aircraft industry insiders.

The official reason given for the cancellation for the project was it had failed to meet a key design criteria as an all-weather jet fighter due to failing to overcome the issue of incorporating a working radar design into the nose cone. This new policy arose from the November British mission to Australia on developing aircraft Aircraft Development Mission design and cooperation.

From this point forward the policy was to adapt proven aircraft for Australian conditions, not start from scratch. Along with this decision, a series of negative reports by the U. Ministry of Supply were cited about the CA, which contained false assumptions and data comparisons, that led to terse rebuttal letter from Sir Lawrence J Wackett to U.

Certified. Let the revolution begin.

In correspondence CAC stated "It is not possible to make significant changes to the Sabre for installation Avon engine area without a team of engineers that has been extended to work on a long-range fighter aircraft".

The decision by the Australian Department of Defence Production to grant permission for the distribution of the detailed design drawings and wind tunnel tests of the CA by the U. The wind tunnel tests carried out by the Royal Aircraft Establishment on the CA and the history of Soviet Agents Wilfred Vernon and others associated with the Royal Aircraft Establishment prior to have led to this conjecture on the similarities.

Volume Carlton, Victoria: Melbourne University Press. Australian Military Experimental and Prototype Aircraft. Lulu Enterprises Incorporated. Retrieved 13 August The Commonwealth Aircraft Corporation produced Boomerangs under the production contract numbers CACACA and CAwith aircraft supplied under each subsequent contract incorporating modifications and improvements. The Boomerang is significant as the first combat aircraft designed and built in Australia.

During these campaigns, the ill-prepared Allied air forces in the Pacific suffered devastating losses. However, the British aircraft industry had long been hard-pressed to meet the needs of the RAF. Although United States companies had enormous aircraft manufacturing capacity, their output was destined for US air units.

When new aircraft built overseas did become available, they would be shipped long distances in wartime conditions, with consequent delays and losses.

CAC examined the possibility of designing and building fighters. The main challenge was the fact that fighter aircraft had never been built in Australia. Consequently, the Twin Wasp was a logical choice for a stop-gap fighter design.

The Wirraway likewise provided a starting point for the Boomerang's airframe. Like the latest fighters at the time, planning for the Boomerang included automatic cannons. As no such weapons were manufactured locally, a British-made Hispano-Suiza 20 mm which an Australian airman had collected as a souvenir in the Middle East was reverse engineered. Lawrence Wackettgeneral manager and former chief designer of CAC, recruited designer Fred Davidan Austrian Jew who had recently arrived in Australia as a refugee.

As David was technically an enemy alienhe was interned by Australian immigration officials.

The Boomerang was a small fighter, designed with an emphasis on manoeuvrability. It had an overall length of just 7. Although the original intention had been to use as many Wirraway components as possible, the final design was quite different, with shorter wings, a shorter, wood-sheathed, aluminium-framed fuselage, increased strength for combat stresses and a new centre section. On 15 July, No. It was found that the Boomerang was faster in level flight than the "Zero", although the Buffalo out-manoeuvred it.

Its pilots were better protected, with generous armour plating, than Japanese fighter pilots. As test and trial flights commenced, CAC had already begun work on a new variant, the CA, to address the Boomerang's deficiencies in speed, climb and ceiling.

CAC eventually returned to the Twin Wasp, to which it added a General Electric B-2 turbo-supercharger mounted inside the rear part of the fuselage, new propellor gear, a geared cooling fan influenced by intelligence reports from Europe regarding captured German BMW twin-row radial engines, which were used by the Focke-Wulf Fw A and a larger, squared-off tailfin and rudder. Testing of later Boomerang variants found that they compared favourably with the Spitfire Mk V and early Thunderbolts and Mustangs.

On 19 OctoberCA A bu. The third Boomerang fighter unit, No. On the evening of 20 MayFlight Lieutenant Roy Goon became the first Boomerang pilot to scramble on the Australian mainland against Japanese bombers. The squadron was only modestly successful however.

The Boomerang's low top speed and poor high altitude performance meant that No. On the only occasion [ when? The Boomerang found its niche as a light ground attack aircraft, a vital role as the ground war in the jungles of the South West Pacific theatre was often characterised by widely dispersed, small unit actions, fought at close quarters, with uncertain front lines. The Boomerang was ideal in this role because it: had the range to go wherever it was needed when it was based close to ground operations; had heavy armament; was agile and easy to fly, meaning that pilots could get close to ground targets, avoid ground fire and rough terrain and; featured extensive armour plating and a wood and aluminium airframe, that could withstand significant battle damage.

Some of the aircraft were shot down, including two accidental "kills" by US forces, and many were damaged during accidents while landing, often because the Boomerang was prone to ground looping. Flying in pairs one to observe the ground, the other to observe the air around themtheir tasks included bombing, strafing, close infantry support and artillery spotting.

When attacking larger enemy formations Boomerangs often operated in conjunction with larger aircraft. The sole CAA was used for research by No. A full-scale, airworthy replica with many original parts is based in the United States. Several others are under restoration to fly in both Australia and the USA. This includes A which is currently being restored to airworthy status. Data from The Great Book of Fighters [8].
