S U P E R S O N I C J E T The adaptation ofcareful aerodynamic design is a particularly good machineproduced with excellent performance in a higher acceleration.The design adjustments to prevent this buffeting are based onthe American-developed theory of 'area-ruling' the fuselage tominimize drag and turbulent areas. The speed of this jet isabout 1,235 km/h which is greater than 5 times the speed ofsound which is often reffered as hypersonic. Designers also usethe Supersonic area rule and the Whitcomb area rule tominimize sudden changes in size and maximum its velocity.Some designs of supersonic transports possessed swing wingsto give higher efficiency. As Mach numbers increase, thedensity behind the shock also increases, which corresponds toa decrease in volume behind the shock wave due toconservation of mass. Hence, the body of our car should be inlow mass and high in stability.

K I N G C O B R A Used to adapt

the concept of velocity and acceleration by its movement when ittries to bite its victim. The reading taken is just less than onesecond. The cobra’s head is of an aerodynamic shape which canreduce the occuring drags.

RESEARCH, SKETCHES & MODIFICATION

Aerodynamics can be defined as the study of air flow through a body primarily when in motion. The objective of a good

aerodynamic design is to reduce drag and increase the downforce. Two factors that can help in inceasing the speed of car are the

drag force and lift or downforce.



A streamline design is one

which objects that move through a gas

or liquid which is shaped to match the

lines and reduce the energy required to

produce the motion. Upon this

discovery, we have come with a design

which applies this principle in order to

reduce friction.

The first step in designing Team Impusion car was to observe the existing

car designs and the general physical principles that affect their

performance. This included research in basic aerodynamic principles.

To create an object, around which air can flow smoothly, the profile of the object in all three dimensions has tobe carefully considered. A fast moving object must be designed in order that it causes the minimum disturbanceand movement in any fluids through which it is travelling. To achieve this the object must be designed toincorporate curves that can guide fluids from front to rear in a smooth manner. This will minimise thedisturbance caused in the fluid. The aim is that the airflow will follow the objects surface; if it does not then flowseparation occurs and a void or low pressure spot will form behind the object resulting in eddies. If an objectcauses disturbance in a fluid through which it is passing then the object is transferring energy to that fluid. Thisultimately means that the object’s own kinetic energy and thus velocity are being reduced. It is thereforedesirable that an object causes as little disturbance in a fluid as possible.

SCREW EYES

BALL BEARING

Sic Titanium Instead of the ordinary screw eyes, we have proposed the

idea of adapting the SIC Titanium for screw eyes where through research

,they are proven to be super hard and super light. Another feature that

makes this corrosive-free and low-density material stands high is

because it has the least friction among the many types.

Treated Ball Bearing Uses this size of 1.5 x 4 x 2. Bearings are made of Chrome Steel and can rotate up to

115,000 rpm, each bearing has 2 metal shields to protect the bearing from dust or any

possible contamination, also bearings are pre-lubricated with grease.

Our wheels were custom-made. This ensured high quality finish. We experimented with nylon and silicon. We

used nylon based for its lighter weight and machineability. For axels our options were steel, silver steel, carbon-

fibre and hollow aluminium. Weight ultimately made the decision for us.

Ceramic is the new prolonged endeavor! It islighter, smoother, stiffer, harder, corrosion resistant, and electrically resistant. Thesefundamental characteristics allow for a wide range of performance enhancements inbearings. Ceramic bearings dissipate heat quickly, reducing friction and wear whilemaintaining a precision smooth surface. Today's leading edge ceramics are made ofSilicon Nitride (Si3N4) and have characteristics similar to the heat absorbing, highlyresilienttiles on the Space Shuttle.





After a thorough

research, our car is finally revealed to

compete in the game.

The cars were manufactured using CAD/CAM technology tocut the desired shape from a block of balsa wood. Handfinishing was then required before the process of paintingand fitting of the wheels.

1- When the manufacturing process is completed, the wheels

are fixed to the car to be tested in the Scout Wind Tunnel.

2- Next, screw eyes are fixed to the bottom of the car to ensure

that the car is well-fixed on the Scout Wind Tunnel.

3- Then, the Scout Wind Tunnel is turned on. The air flow

around the car is observed.

MARKETING, SPONSORSHIP &

EXPENDITURE



We have several strategies to market our car. The following are the steps taken :

1 An attractive booth with interesting information about our car is being set up.2 Specially ordered aerodynamic pens and stickers are sold and given away to

our booth visitors.3 LCD + speakers are used to present our slide show in order to attract visitors.

COMPLIMENTS

We sent out letters to many potential companies around the state asking for sponsorship and assuring them that their gooddeeds are all done for the sake of supporting the educational programme. Those who were moved contacted us and we thenwent out to speak with them and explaining in details about the competition and how important and meaningful their supportwould be for our team.After being crowned the overall champion at the regional level competition, we set ourselves the aim of raising RM10,000 insponsorship in order to cover the expenditures needed in the finals. Our gratitude must go to all our sponsors for enabling usto prepare well for the forthcoming game.
