Takashi YorinoDebut1990 1000 km of Fuji (787)(787B)RacesWins21100Constructors' Championships0Drivers' Championships0The Mazda 787 and its derivative 787B are that were developed by Japanese automobile manufacturer for use in the, and the from 1990 to 1991. Designed to combine a mixture of the (FISA) regulations with the (IMSA) regulations, the 787s were the last racing cars to compete in the World and Japanese championships, using Mazda's engine.Although the 787 and 787B lacked the single lap pace of World Championship competitors such as, and, as well as Japanese Championship competitors and, the 787s had reliability that allowed them to contend for their respective championships. The reliability of the cars eventually paid off in 1991 when a 787B driven by, and went on to victory in the. As of 2018, this remains the only victory by a car not using a design, a record likely to never be repeated due to regulation changes until recently. For the 2020-2021 season a new FIA Prototype Hypercar class will now allow a Rotary engine under the NSU Wankel patents.
It was the first victory by a manufacturer, and the only such victory until won the.A total of two 787s were built in 1990, while three newer specification 787Bs were built in 1991. Contents.Development The initial design of the 787 was an evolution of the and 767B designs that had been used by Mazda in 1988 and 1989. Many mechanical elements of the 767 were carried over by Nigel Stroud when he designed the 787, but with some notable exceptions. Foremost was the replacement of the 767's. In its place, the brand new was installed. The custom-built R26B featured a nearly identical layout and displacement, but included new design elements such as continuously variable intakes and three per rotor instead of the 13J's two along with carbon fibre apex seals and variable length trumpets.
Jan 30, 2020 With more than 100 quality products, Redline is one of the best car oil brands in the marketplace today known for their cooling additive, WaterWetter, for the industrial, marine, motorcycle and automotive markets. Based in Benicia, California, Redline has a strong reputation among car-enthusiasts and keen racers.
This allowed for a maximum power output of 900 hp (670 kW), which was limited to 700 hp during the race for longevity. 's five-speed manufactured by Porsche was retained.Other modifications made to the 787's design included a relocation of the.
Initially placed beside the cockpit on the 767, a new single radiator was integrated into the nose of the 787. Air moved from the blunt nose of the car underneath the bodywork and through the radiator before exiting in front of the windshield. A was located at the radiator exit to increase front-end. This new radiator location also meant a redesign of the doors of the car, where the old radiator design had been located. The intake in front of the door and exit behind were no longer necessary and were thus not included, giving the 787 a smoother bodywork design on top.
To aid in rear engine and brake cooling, intakes were placed on the side bodywork, immediately above the exhaust cooling vents.As before, Stroud's monocoque design was built from and by Advanced Composite Technology in the United Kingdom. Carbon fiber body panels were affixed to the two initial chassis that were built in 1990. 787B Following the 1990 season, Mazda continued development of the 787 chassis in order to make improvements on its pace and reliability. One major development was the intake system for the rotary engine.
In the past, Mazda had developed variable-length telescopic intake runners to optimize engine power and torque for varying RPM levels. For 1991, the system became continuously variable, rather than previous versions that had steps for different engine ranges. This resulted in an increased torque of 608 N⋅m (448 lb⋅ft) at 6,500 rpm.
The 787B's onboard controlled the action of the telescopic intake. Another main improvement was the change in suspension geometry which allowed for larger wheels to be fitted along with carbon ceramic brakes, a first for a Mazda racing car.The engineers at Mazdaspeed determined that fuel efficiency was crucial for achieving victory so they restricted the redline of the engine to 8,500 rpm thus reducing the power output to 650 hp (485 kW). Emphasis was put on high cornering speeds rather than attaining high top speeds at the straight sections of the track.
Jacky Ickx was appointed as an advisor to guide the team in preparing the car.Three new 787Bs were built for 1991, while the two existing 787s were also upgraded with the new intakes. For Le Mans, two 787Bs were entered along with a 787 in the C2 class which were subject to greater restrictions than the newly introduced C1 class in which the cars were fitted with 3.5-litre Formula One inspired naturally aspirated engines. The third car was built primarily to replace the Le Mans winning car in competition but it retired in 1992 with no notable success.
Mazda 787B on display at Le Mans 2011 24-hour raceAfter Le Mans, the winning car (787B-002) was retired from duty while the other two cars (787B-001 and new 787B-003) continued to race. Mazda would go on to finish fourth and fifth in the Japanese and world championship respectively, with a season high (besides Le Mans) third in the 1000 km Fuji race (a JSPC race). As Mazda used different drivers throughout the season, none of their drivers finished in the top 10 in points.After the 1991 24 Hours of Le Mans, the 787B would compete once more at the last race of the season, the 1991 (finishing 9th and 10th). At the end of the season, the Group C series was replaced by the 3.5-litre World Sports Championship and therefore Wankel-type rotary engines would no longer be allowed to run as they were outlawed and, as per 's earlier decision, 3.5-litre engines similar to those used in became the new formula for the 1992 season.
The following year, Mazda entered the MXR-01, based on the and powered by a Judd unit, without much success (placed fourth at Le Mans in 1992).Despite the Le Mans success of the 787B and its Wankel powerplant, Mazda did not exploit its historic victory through marketing campaigns and advertising. It partially improved sales for Mazda's road cars, however. In the United Kingdom, Mazda would introduce a special edition of its with the racing colour and also a BBR (Brodie Brittain Racing) conversion; only 24 were produced and the car is one of the most sought after special edition cars of its model. Long a proponent of the rotary engine, Mazda maintained a rotary-engine road car for many years, though sales of the were stopped in North America after the 1995 model year (with Japanese-market production ending in 2002) until the introduction of the 2003.

It set a world airspeed record and a transcontinental speed record across the United States. The H-1 Racer was the last aircraft built by a private individual to set the world speed record; most aircraft to hold the honor since have been military designs. Contents.Design and development During his work on his movie, employed to maintain the fleet of over 100 aircraft used in the production. The two men shared a common interest in aviation and hatched a plan to build a -beating aircraft.

The aircraft was given many names, but is commonly known as the H-1. It was the first aircraft model produced by the Hughes Aircraft company.Design studies began in 1934 with an exacting scale model (over two feet in length) that was tested in the wind tunnel, revealing a speed potential of 365 miles per hour (587 km/h). Technical details was a paramount design criterion resulting in 'one of the cleanest and most elegant aircraft designs ever built.' Many groundbreaking technologies were developed during the construction process, including individually machined that left the skin of the aircraft completely smooth.
The H-1 also had retractable landing gear to further increase the speed of the aircraft, including a fully retractable hydraulically actuated. It was fitted with a twin-row 14-cylinder of 1,535 cubic inches (25.15 l), which although originally rated at 700 horsepower (522 kW), was tuned to put out over 1,000 horsepower (750 kW).Due to two different roles being envisioned for the racing aircraft, a set of short-span wings for air racing and speed records and a set of 'long' wings for cross-country racing were prepared.Operational history. Front of H-1 RacerHughes piloted the first flight on 13 September 1935 at Martin Field near Santa Ana, California, and promptly broke the world landplane speed record clocking 352.39 mph (567.12 km/h) averaged over four timed passes.
The ship was loaded with a minimal amount of fuel to keep the weight down, and Hughes was not supposed to make the 3rd and 4th passes, exhausting the fuel supply. Hughes managed to crash-land in a beet field south of without serious damage to either himself or the H-1.: 133–134 When his compatriots arrived at the crash site Hughes said 'We can fix her; she'll go faster.' At the time, the world speed record was 440.7 mph (709.2 km/h), set by a in October 1934.Hughes later implemented minor changes to the H-1 Racer to make it more suitable for a transcontinental speed record attempt. The most significant change was the fitting of a new, longer set of wings that gave the aircraft a lower. On January 19, 1937, a year and a half after his previous landplane speed record in the H-1, Hughes set a new transcontinental speed record by flying non-stop from to in 7 hours, 28 minutes and 25 seconds. He smashed his own previous record of 9 hours, 27 minutes by two hours. His average speed over the flight was 322 miles per hour (518 km/h).Considering the contemporary service aircraft were biplanes, Hughes fully expected the (USAAC) to embrace his aircraft's new design and make the H-1 the basis for a new generation of U.S.
Fighter aircraft. His efforts to 'sell' the design were unsuccessful. In postwar testimony before the Senate, Hughes indicated that resistance to the innovative design was the basis for the USAAC rejection of the H-1: 'I tried to sell that airplane to the Army but they turned it down because at that time the Army did not think a cantilever monoplane was proper for a pursuit ship.' Aviation historians have posited that the H-1 Racer may have inspired later radial engine fighters such as the and the. After the war, Hughes further claimed that 'it was quite apparent to everyone that the had been copied from the Hughes H-1 Racer.' He noted both the wing shape, the design and the general similarity of the Zero and his racer., designer of the Mitsubishi Zero strongly denied the allegation of the Hughes H-1 influencing the design of the Japanese fighter aircraft.The Hughes H-1 Racer is featured in the 1940 RKO Radio Pictures movie.
Disposition. Jim Wright's H-1 on display at Oshkosh WisconsinA non-flying replica was displayed in the from 1993 to 1994, after which it was placed in storage.Jim Wright of, built a full-scale replica of the H-1 that he first flew in 2002. His replica was so close to the original that the FAA granted it serial number 2 of the model. His achievement in recreating the aircraft was heralded in virtually every well-known aviation magazine of the time.On August 4, 2003, Wright unveiled his H-1 replica at the 2003 at. On his way home to Oregon, he refueled the aircraft in. Wright met briefly with local reporters and said that the aircraft had been having propeller 'gear problems.'
An hour after taking off, the aircraft crashed just north of the in, killing Wright. The replica, slated to be used in the film, was completely destroyed. The official accident report detailed the failure of a counterweight on the. On December 17, 2003, was dedicated as Jim Wright Field.A static replica H-1 was displayed on a pole alongside Hughes’ “” at Long Beach when the latter aircraft was displayed in a dome adjacent to the. Other non-flying replicas are displayed at the Thomas T.
Beam Engineering Complex at the (donated by the in 1988) and the Santa Maria Museum of Flight. As of 2016 another H-1 replica is being built at the San Diego Air & Space Museum.

What Hughes actually asserted was that it was plain from examination of the two that the Zero was substantially a copy. An aside from Bill Utley, the Hughes company publicist, noted that one Al Ludwick had given details of pre-war inspection of the H-1 by Japanese generals at a New Jersey hangar. No actual evidence of copying beyond similarity of design is offered otherwise.
Witnesses on the ground testify that Mr. Wright turned the aircraft away from park visitors and into a small bluff in an apparent attempt to spare those on the ground.Citations.
