“Lemme tell ya, these ain’t no ordinary finches we’re talkin’ about. These here are the Angry Birds, the ones that’s gonna kick you in the ‘nads! And they’re the ones on your side. They must be from Galapadapados, or sumptin’.”

Help the Birds smoke out the Swines!

The pigs have got wicked and the birds angrier…

Enough of the virtual world they say, enough of the android, apples apps! Out from your computer screens, on to the battlefield, they are here to settle the scores once and for all…

You know the game. You definitely do! The endearing little Birds suddenly turn into combative warriors when a group of pigs steal their eggs. In order to retrieve the eggs, they have to fight against the pigs and destruct the structures in just few and limited shots.

After the overwhelming success of Angry Birds Seasons, Rio and Magic; we at NITK Surathkal presents a real life version of this addictive marvel, Angry Birds- Engi; a version that involves, not just mere Newtonian physics, but also Aerodynamics and some ‘smoky’ Chemistry!

This Engineer, an opportunity knocks your doors to showcase to skills and creativity by building your own smoke cannon/vortex generator – your weapon against the evil pigs.

Help the Birds smoke out the Swines!

You have to design a smoke cannon/vortex generator that generates vortices of smoke with sufficient momentum to destroy/topple the targets (balloons). Arenas will contain obstacles and pigs of different strengths. The ‘pigs’ need to be toppled/ destroyed either by the smoke vortices directly hitting the target or by making the surrounding objects fall on the ‘pigs’.

 

Smoke: The source of smoke should be a chemical reaction taking place inside the cannon. Fuels like coal/charcoal/firewood cannot be used to generate smoke. The smoke should preferably be of high density so that it is clearly visible and gets the necessary momentum. Reagents can be refilled manually. Contact of the smoke ring with the target should be distinctly visible. The smoke should be non-toxic. Innovations in the reaction will fetch special credit.

 

Vortex Generator: The participants are free to decide on the shape and design of the cannon keeping in mind its efficiency to generate high speed vortices. One end of the vortex generator should be covered with a membrane of any suitable material. The impulse (provided by the catapult) applied to the membrane must result in the output smoke rings. The dimensions of the vortex generator should lie within 1m X 0.5m X 0.5m, the longest dimension being along the length.

 

Catapult: A catapult is provided to rest the vortex generator as shown in the figure below. An elastic slinger is employed to provide the necessary impulse to the membrane of the vortex generator. The catapult can be adjusted for a range of sizes of vortex generators. The distance between the ends of the catapult is 0.5m. The participants are required to get their own slingers, which can either be attached to the vortex generator or the catapult.

 

Arena: The arena will more or less resemble one of the levels of the actual game ‘Angry Birds’. In the setup, there are balloons at various points that resemble the pigs in angry birds. There will be pins at various points which can be used to burst the balloons (pigs) on impact. The bursting of the balloon is expected to initiate another contraption. The exact arena of level 1 and the judging criteria will be uploaded soon. The subsequent levels will only be disclosed on the spot.

LAYOUT OF THE SETUP

 

 

 

• Participants need to submit a schematic diagram of the vortex generator, supported by a description of the mechanism and the reaction in not more than 200 words.
• The abstract should be sent to chemicalevents@engineer.org.in at the latest by 20th October 2011.
• A team can have a maximum of 4 members.
• All members of the team are to be enrolled as students in an educational institute.
• No person can be part of more than one team.
• The decision of organizing committee is final and binding on all.
• Special credit will be given to teams with creative design and reaction.
