Kremer Competitions

UPDATE - 16/12/15
Following serious interest from a number of potential competitors it has been decided to keep the Kremer International Sporting Aircraft 
Competition prize of £100,000 open. The committee of the RAeS human powered flight group look forward to this very challenging prize being attempted and won.

Anyone intending to enter the Kremer International Sporting Aircraft Competition is reminded that it is recommended that they advise the Organisers at the earliest opportunity as outlined by Rule 6.2) and 6.3) , to establish that the proposed entry is acceptable in respect of the attributes required of an HPAS.

Thanks to the generosity of the late Mr Henry Kremer The Royal Aeronautical Society currently organises the following competitions:

The Kremer International Marathon Competition

Prize: £50,000 (Fifty Thousand Pounds Sterling)
The course for the Kremer International Marathon Competition is around two turning points. The aircraft starts from rest flies two outer circuits, one figure of eight, then two more outer circuits, such that the distance including turns is thus approximately the distance of the Marathon course in athletic events. This distance must be flown in one hour or less. The aircraft must be in continuous flight, and must make a landing satisfactory to the observers. At certain points on each circuit there is a minimum height obligation. The entrant may select the location of the course, which must then be approved.

The Kremer International Sporting Aircraft Competition , ( see annoucement above )

Prize: £100,000 (One hundred thousand pounds Sterling)
The purpose of this competition is to promote the production of an aircraft suited to athletic competition. In particular it is necessary to specify and design an aircraft able to operate in normal weather conditions, as encountered in the United Kingdom. The prize of £100,000 will be awarded to the first entrant successfully demonstrating a human powered aircraft in accordance with the rules of the competition.

The Robert Graham Competition

£500 annual prize for work by a student on a subject appropriate to human powered flight.
The purpose of the competition is to foster knowledge in the art and science of human powered flight. The competition is open to undergraduates and other students of engineering, technology, human physiology and other relevant disciplines at universities, polytechnics, colleges of further education and sixth form colleges in the United Kingdom. Any project entered must form an integral part of a course of studies. The work can take the form of experimental research or engineering design and must have a clear application to human powered flight. Each sponsoring college may approve one entry in each discipline per year. 

Schools Competition

£1,000 annual prize for flight by a youth group.
Open to any Youth Group in the UK, this competition was launched in 2006. Young people have always shown their ability to pilot. Now here is encouragement for them to be involved in the creation of the machine. The conditions are far less stringent than for any previous competition. A cash prize and a trophy will be awarded annually for the flight of longest duration that year. Two ground-handlers are allowed to assist in the take-off. It can be done. The precedent for this is the Aslam HPA built by students of Dr Keith Sherwin in Singapore. Upper age limit is 18. The RAeS HPFG currently includes Dr Bill Brooks, Professor John Wimpenny, Dave Barford, Dr Alex Forrester, Martyn Pressnell, John McIntyre and Chris Roper, all of whom have designed HPA.

We are providing information and support to participating teams. HPA have been built with very modest equipment, and construction should be well within the scope of a school`s workshop. It is anticipated that flights could be performed on a typical school playing field, or similar open space. The rules also constrain that the plane must be deriggable suitable for transporting.
