Bluebird Jet Boat Floats Again, 51 Years After Fatal Crash 4 August 2018, by Jill Lawless
Bluebird jet boat floats again, 51 years after fatal crash 4 August 2018, by Jill Lawless The jet-powered Bluebird roared past 300 mph (482 kph) before it vaulted into the air, flipped and crashed into the lake, breaking in two and killing the 45-year-old Campbell. It was 34 years before divers managed to raise the Bluebird's wreckage from the bottom of 150-foot (45-meter) deep lake in March 2001. Human remains were found near the boat and confirmed by DNA testing as belonging to Campbell. In September 2001, his body was taken on a final boat trip around the lake where he died before being buried in a nearby churchyard. The restored Bluebird K7, which crashed killing pilot Donald Campbell in 1967, takes to the water for the first A team has been working for 17 years to restore time in more than 50 years off the Isle of Bute on the the vessel and hopes to return it to the Lake District west coast of Scotland, Saturday Aug. 4, 2018. The next year. famed jet boat Bluebird has returned to the water for the first time since a 1967 crash that killed pilot Donald Campbell during a world speed-record attempt. Watched by Campbell's daughter Gina Campbell, the restored Bluebird was lowered Saturday into Loch Fad on Scotland's Isle of Bute, where it will undergo low-speed tests.(David Cheskin/PA via AP) The famed jet boat Bluebird returned to the water Saturday for the first time since a 1967 crash that killed pilot Donald Campbell during a world speed- record attempt. -

LOCAL LAND-SPEED RECORD-HOLDING CONNECTIONS Iain Wakeford 2016
LOCAL LAND-SPEED RECORD-HOLDING CONNECTIONS Iain Wakeford 2016 month ago I wrote a small piece on Britain’s first Motor Grand Prix that A took place in 1926 at Brooklands, following Henry Segrave’s win in the French Grand Prix the previous year. The 1926 race was won by a Frenchman, with Malcolm Campbell coming second, and Henry Segrave having to retire, but the two Brits were to lock horns on many other occasions, not least for the more prestigious title of being the fastest man on land. They were joined in that pursuit by John Godfrey Parry-Thomas, who lived in a bungalow called ‘The Hermitage’ in the middle of the race track at Brooklands. Malcolm Campbell was the first of the three to gain the land-speed title in September 1924 when he drove his Sunbeam across Pendine Sands in South Wales at 146.16mph. The following July he increased the record, becoming the first person to travel at over 150mph, but that record was smashed the following April when Parry Thomas in his car ‘Babs’ crossed the sands at 170mph! Parry Thomas didn’t have the wealth of Segrave or the prestige of Campbell, and in fact ‘Babs’ was adapted from a second-hand car that he had bought from the estate of Count Zbrorowski (of Chitty Bang Bang fame) following his death at the Italian Grand Prix at Monza in 1924. Sadly Malcolm Campbell in his ‘Bluebird’ regained the record from Thomas at Pendine in February 1927, but when Thomas tried to get it back the following month he lost control of Babs and was killed as the car rolled and slid upside-down along the beach at over 100mph. -
The Stepped Hull Hybrid Hydrofoil
The Stepped Hull Hybrid Hydrofoil Christopher D. Barry, Bryan Duffty Planing @brid hydrofoils or partially hydrofoil supported planing boat are hydrofoils that intentionally operate in what would be the takeoff condition for a norma[ hydrofoil. They ofler a compromise ofperformance and cost that might be appropriate for ferq missions. The stepped hybrid configuration has made appearances in the high speed boat scene as early as 1938. It is a solution to the problems of instability and inefficiency that has limited other type of hybrids. It can be configured to have good seakeeping as well, but the concept has not been used as widely as would be justified by its merits. The purpose of this paper is to reintroduce this concept to the marine community, particularly for small, fast ferries. We have performed analytic studies, simple model experiments and manned experiments, andfiom them have determined some specljic problems and issues for the practical implementation of this concept. This paper presents background information, discusses key concepts including resistance, stability, seakeeping, and propulsion and suggests solutions to what we believe are the problems that have limited the widespread acceptance of this concept. Finally we propose a “strawman” design for a ferry in a particular service using this technology. BACKGROUND Partially hydrofoil supported planing hulls mix hydrofoil support and planing lift. The most obvious A hybrid hydrofoil is a vehicle combining the version of this concept is a planing hull with a dynamic lift of hydrofoils with a significant amount of hydrofoil more or less under the center of gravity. lit? tiom some other source, generally either buoyancy Karafiath (1974) studied this concept and ran model or planing lift. -

Human Powered Hydrofoil Design & Analytic Wing Optimization
Human Powered Hydrofoil Design & Analytic Wing Optimization Andy Gunkler and Dr. C. Mark Archibald Grove City College Grove City, PA 16127 Email: [email protected] Abstract – Human powered hydrofoil watercraft can have marked performance advantages over displacement-hull craft, but pose significant engineering challenges. The focus of this hydrofoil independent research project was two-fold. First of all, a general vehicle configuration was developed. Secondly, a thorough optimization process was developed for designing lifting foils that are highly efficient over a wide range of speeds. Given a well-defined set of design specifications, such as vehicle weight and desired top speed, an optimal horizontal, non-surface- piercing wing can be engineered. Design variables include foil span, area, planform shape, and airfoil cross section. The optimization begins with analytical expressions of hydrodynamic characteristics such as lift, profile drag, induced drag, surface wave drag, and interference drag. Research of optimization processes developed in the past illuminated instances in which coefficients of lift and drag were assumed to be constant. These shortcuts, made presumably for the sake of simplicity, lead to grossly erroneous regions of calculated drag. The optimization process developed for this study more accurately computes profile drag forces by making use of a variable coefficient of drag which, was found to be a function of the characteristic Reynolds number, required coefficient of lift, and airfoil section. At the desired cruising speed, total drag is minimized while lift is maximized. Next, a strength and rigidity analysis of the foil eliminates designs for which the hydrodynamic parameters produce structurally unsound wings. Incorporating constraints on minimum takeoff speed and power required to stay foil-borne isolates a set of optimized design parameters. -
Round up Saturday 3Rd November 2018 the 48Th Annual Powerboat Records Week Will Be Remembered As the Week of Flat Water
Coniston Power Boat Records Week is at Coniston Power Boat Records Week. November 12 · Coniston, United Kingdom · Coniston Power Boat Records Week 2018 – Round Up Saturday 3rd November 2018 The 48th Annual Powerboat Records Week will be remembered as the week of flat water. There were very few times the water state restricted the type of craft on the run, resulting in a busy week for the timekeepers with no lost time due to the weather. As a Union Internationale Motonautique (UIM – World Governing Body of powerboat racing) calendared event, Coniston Powerboat Records Week is open to competitors from around the globe. This year we were delighted to welcome international competitors from Denmark and Ireland, not to mention from all corners of tHe UK. Some of tHe week's Highlights include: The youngest competitor of the week was 17 year old Thomas Mantripp. Thomas, from Lowestoft, entered 3 classes. Following in his father and grandfather’s footsteps, Thomas had already won the British National Championship in 2018 in the GT30 class. His biggest success of the week was in O175 Hydroplane class witH a new World and National record at 89.00mph. The outboard hydroplane class of boat is driven from a lying down position. For a 17-year-old to set 3 World & National Records all over 80mph takes outstanding courage and trust in his team who were preparing the boat. As well as being the youngest entrant, most successful entrant and the most meritorious performance of the 48th Powerboat Records Week, Thomas and his team were awarded the Team of the Meeting Trophy. -
