What is Bloodhound SSC?
� Bloodhound SSC is the name of a project aiming to break the land speed record with a
car powered by a jet engine and a rocket.
� It is designed to reach approximately 1,000 miles per hour (1,609 km/h). It is being
developed and built with the intention of breaking the land speed record by the largest
ever margin.
� If funding is obtained the construction should be complete by the end of 2011 and the
record attempts may happen in late 2011 early 2012

Bloodhound SSC/RapMan Projects
� This Teaching and Learning resource is
intended to give you a few ideas for
RapMan or BfB3000 projects based on
the Bloodhound SSC car. Some are
cross curricular and can involve
different subjects. The following list
highlights some of the project ideas.
� Design and make your own
Bloodhound car- rocket, CO2 or
balloon powered
� 3D terrain mapping… find an area flat
enough to drive a car at 1000mph… and
print a map of it
� Ergonomics… design controls that “fit”
the driver

Design you own Bloodhound SSC
� OK, so designing and making a 1000mph car
would cost you about £10 million… Not the sort of
cash you are likely to carry around with you! So
making a real car is probably a little unrealistic.
� Why not design and model your own
Bloodhound?
� On the next page are lots of images of the real car,
perhaps you could base your design on these or
even try to design your own from scratch. You can
use any 3D CAD program as long as you are able
to export in .stl format.
� Use a RapMan or BfB3000 to 3D print your model

A mini Bloodhound SSC
� If you are feeling a bit more adventurous the
why not try making a mini Bloodhound
powered by a real rocket motor.
� Some parts for the car such as the wheels, fins
or tails can be made with a RapMan or BfB3000
3D printer… could these modifications add to
the performance of the mini Bloodhound?

F1 in Schools Bloodhound
� If you fancy going a little further in the designing and
making of a mini bloodhound SSC then you could consider
taking part in the F1 in schools competition. There is a
special Bloodhound category and details can be found here
http://www.f1inschools.co.uk/
� The bloodhound category has been developed based on the
concept of the World Land Speed Record rules and
regulations - as few rules as possible… so there is ample
opportunity to design and make parts for your design using
a RapMan or BfB3000 printer.
� The current UK record (as of November 2010) is 0.620s to
cover the 20m track (32.25m/s or 116.1kph or 72.14mph)
� Rules and regulations can be downloaded here

BfB one in this case)

A balloon powered Bloodhound
� Building the rocket powered bloodhound is
probably only suitable for older students but
there are opportunities for younger students to
get involved too… balloon power!!
� A simple card chassis with some wheels and a
balloon is all that is needed… and why not
partner primary and secondary schools to
print wheels of your own design using a
RapMan.
� Some lesson ideas and templates are available
on the Bloodhound SSC website
http://www.bloodhoundssc.com/education.cf
m?cit_id=4470 (registration is required).
� And what about those wheels…. Here are some
ideas of wheels printed using a RapMan 3D
printer.

Flat as a pancake…
� You can’t drive at 1000mph on a motorway, so where would you find a suitable
place for a record attempt?
� The requirements for a location to drive at this sort of speed are…
1. Flat ground 2. Smooth surface 3. Large area 4. Reliable surface dry-out period. 5.
Access from road network. 6. Security. 7. Potential for publicity and constructive
competition…. So, how do you find the right location?
� There is a lesson guide about using Google
Earth to find suitable locations on the
Bloodhound SSC website
http://www.bloodhoundssc.com/education.cf
m?cit_id=4476 (registration is needed)
� But why not go one step further … how about
printing a 3D model of the locations using a
RapMan or BfB3000 printer.
� A full guide to using digital height data from
satellites or the NASA Shuttle program can be
found on the BfB wiki

Get a grip…
� I’m pretty certain that Wing Commander Andy Green, the driver of Bloodhound SSC will not want
to make a slip when steering at 1000mph. Flicking a wrong switch or pressing the wrong button
might not be too clever either. So designing ergonomic controls is pretty important.
� Designing hand grips, non slip switches, buttons etc is a project where students can use
anthropometric data gathered from primary or secondary sources to design these controls.
� Using software such as Pro/ENGINEER a simple starting shape can be sculpted using features such
as warp, bend or spline to model the controls. The designs can then be printed in 3D using a
RapMan or BfB3000 printer to test them out.
� More information on the design of Bloodhound controls can be found here

A whole lot of thrust
� About half of the thrust of Bloodhound SSC is
provided by a EUROJET EJ200, a highly
sophisticated military turbofan normally found
in the engine bay of a Eurofighter Typhoon.
� Obviously the design of the fans and turbines
is critically important, so why not design and
3D print some different designs to test and
compare their efficiency?
� There is a Teaching and Learning resource
about turbines on the BfB wiki that can be
easily adapted to testing the thrust that can be
generated (the original project is about
measuring electricity generated by wind
turbines). See
