The R510 series of aircraft are wide-body jet airliners manufactured by Ahuriri Aerospace. First developed in the late 1960s following the success of the R500, it undertook commercial operations with Onekawa Airways in 10 June 1971. Designed for "short and wide" routes in comparison to its smaller cousin, the R510 was the first wide-body airliner ever designed by Ahuriri Aerospace, and one of the first twin-jet wide-bodys in the world. Having been a commercial success, the R510 and its variants remain in service around the globe, and remained in production for over 40 years before the assembly line for the R510 and its variants was closed 10 June 2012.

Development

With the significant commercial success of the R500, it was clear that the growing commercial aircraft market would be a key focus for Ahuriri Aerospace going forward. Whilst there had been preliminary plans to a wide-body design during the development of the R500, these had been relatively immature in their development as Ahuriri Aerospace was not sure if this latest attempt to enter the civilian market would be successful. When the R500 proved their was space in the market for Ahuriri Aerospace to be a significant player, it became a company priority to offer a wide-body aircraft within as short as time as was feasible.

The aircraft that would become the R510 would be focused on "short and wide" routes between major cities and destinations, with the same expectations for range as R500 in the 3,500km to 6,000km but with significantly higher capacity for passengers and freight. This was a continuation of the "minimal risk, clean sheet approach" that had been proven successful in the development of the R500, where a relatively unambitious approach to overall parameters was matched with utilising the latest in manufacturing and aviation technology to provide an extremely robust design.

Variants

R510

The original design of the R510, it entered service with Onekawa Airways in 1971. With a range of 6,000km and a capacity for 180/216/250 passengers in a typical 3-class/2-class/1-class configurations. It has been primarily utilized by airlines on high demand regional and intra-continental routes, connecting major destination hubs. Originally powered by two AA3300 high bypass turbofans producing a total of 52,000lbf each, it was also offered with the option to use the XYZ offered by ABC. As of 2020 there are still X0 aircraft in service, with a total amount of X00 sold before production ceased in 1985.

It was further developed into the R510F, a dedicated freighter equivalent. Able to carry 80,200 lb of cargo, its interior had space to accommodate 22 LD3 containers. The R510F proved popular amongst freight operators, selling X00, with X00 still remaining in service in 2020.

R511

The first lengthened variant, designed alongside the original R510, the R511 fuselage was stretched an additional 6.02m to increase passenger capacity. Able to accommodate 210/256/292 in typical 3-class/2-class/1-class configurations with the same 6,000km range, the R511 proved to be more popular amongst operators then the original R510. Utilizing the same engine options as the R510 as well as the option for the AA3350 engine producing 55,000 lbf and a mild increase in fuel capacity, it would makes its first commercial flights with Air Kermat in 1972, followed a year later by the Yisraeli Royal Continental. The R511 went on too sell X00 units by 1985, with X0 still in service by 2020.

The R511 was developed into the R511F and the R511ER. The R511F was the dedicated freighter equivalent, now able to carry 30 LD3 containers and total weight capacity of 90,000 lb and 30 LD3 containters, it would become more popular then the R510F, with the first R511F taking flight with Ozeros Express in 1973. The R511ER significantly increased internal fuel capacity for the R511, extending total range to 8,500km. The R511ER increased range greatly opened up opportunities for travel on the platform. Able to carry passengers from Onekawa-Nukanoa to destinations in the Periclean and the vast majority of Ochran, it sold X00 aircraft by 1985, with X0 still in service in 2020.

R512

The 1989 Vertical Training Solution program was established by Ahuriri Aerospace as a way to standardise cockpit systems, increasing interoperability and allow easier transfernce for pilots on Ahuriri Aerospace aircraft. Based off the new cockpit enviosned for the R500, this was adapted for use on the R510 series. This would result in the R510 and R511 and their variants to be pulled off production and replaced by the R512 and R513.

The R512 would be the new equivalent of the R510. Offering the same carrying capacity in passengers and cargo, it incorprated the new glass cockpit featuring side-stick controllers. the VTS program also had all future Ahuriri Aerospace aircraft fitted with fly-by-wire technology, with more tranditional analog control systems utilised as backup. There was also a greater inclusion of CFRP that reduced the weight between the original R510 by 4t and reducing fuel burn by 1.2%-1.6 %. The first R512 undertook commercial flight with Onekawa Airways in 1991. It went onto to sell X00 aircraft, with X0 still in service by 2020.

Despite design an development of the R510, a dedicated freighter equivalent to the R510F wasn't developed, due to its relatively unpopularity in comparison to the R511F. Ahuriri Aerospace did offer passenger-to-freight conversions of the R512, which became known as the R512CF.

R513

The VTS development of the original R511, it maintained the same performance and capacity as the original R511 but with the addition of a new glass cockpit, fly-by-wire control system and increased use of CFRP materials, decreasing weight by 5t in comparison to its predecessor. This weight savings was estimated to save 1-1.4% in fuel burn in comparison to the R511. It's first flew with Air Kermat in 1992.

The R513F and R513ER were also developed alongside the baseline R513. Incorprating the same changes as all post-VTS Ahuriri Aerospace aircraft, these variants would go on to considerable finacial success. The increased use of CFRP allowed for an additional increase in range over the original R511ER, from 8,500km to 8,700km. Royal Continental Airways become the first customer for the R513ER in 1992, with a total of X00 aircraft sold, and with X0 still in service by 2020.

The R513F would be as popular as the original R511F, with the savings in weight through the use of CFRP increasing total weight tolerance to increase to 100,000lb, although capacity for LD3 containters remained limited to 30. It would undertake first undertake commercial service with Ozeros Express in 1992, with a total of X00 aircraft sold, and with X00 still in service by 2020.
