The Air Challenge

To invent an airplane is nothing.
To fly one is something.
To build is everything.

In its simplest form, a glider is an unpowered aircraft, an airplane without a motor. Gliders,being amazing and graceful machines are about as close as humans can get to soaring like birds.

The aerodynamic and piloting factors that apply to working of a glider are studied and worked upon by students.The key factors in obtaining lift to conquer gravity and allow the glider to glide are shape and surface area and are thus modeled to attain best model by the brilliant minds of engineers.

General Rules:-

TEAM COMPOSITION:   A team must consist of at least three and maximum of four members.

EVENT FORMAT: 

1. All the participating teams must report at the venue of registration on the day of event at the mentioned time.
2. After the closure of registration, a preliminary round will be conducted; an objective test on aerodynamics and related topics.
3. Based on the score of the teams a cut-off will be determined. All the teams above the cut-off will qualify for the main round.
4. The qualified teams will be given a 30 minute workshop on aerodynamics of gliders, working with balsa, properties of glues provided and details of the event.
5. The event begins 15 minutes after the workshop.
6. The duration of the event will be 5 hours by the end of which teams have to:
   • Make their HLG (Hand launch glider) using the tools provided.
   • Make a brief design report showing :
     1. The three views of the parts 
     2. Explanation of choice of design features.
     3. Number of test flights and subsequent design changes.
        (If any)
7. After the end of five hours, the faculty judges will examine the design reports and question the teams. Their marks will be recorded.
8. Then the teams will hand launch their gliders from the roof of mechanical dep’t. Each team will be allowed 3 launches and only the best score as deemed by the team will be taken into account.
9.   Team’s score card will consist of the following :
   1. Design report-    20 pts
   2. Final prototype- 20 pts
   3. Performance table:

   CRITERIA	FOM
   Gliding time	6
   Material saved	2
   Gliding distance	2
   Total	10

   4. Sustainability- 100 pts

    

   NOTE:

   • The points for the design report and final prototype will be decided by the panel of judges.
   • In the performance table:
     • Each second is 4 points.
     • Each square inch of:
       • 5 mm balsa saved is 2 pts.
       • 4 mm balsa saved is 1.5 pts.
       • 3 mm balsa saved is 1 pt.
     • Each metre of distance is 2 point.

    So if a HLG stays air-borne for stays air-borne for 15 seconds, travels a distance of 15 metre and the team has saved 15 square inch of 3mm balsa, 20 square inch of 4mm balsa, and 50 square inch of 5mm balsa;
   Then their score would be:

   CRITERIA	SCORE	WEIGHTED SCORE
   Gliding time	15*4=60	60*6=360
   Material saved	15*1 + 20*1.5 + 50*2 = 145	145*2=290
   Gliding distance	15*2=30	30*2=60
   TOTAL		360+290+60= 710

   
   
   • If the plane stays undamaged after the three launches, it shall be rewarded the 100 pts for sustainability.
   
   
10.  The team with maximum score takes the Aviator crown.

PRIZES AND AWARDS:

• Following are the prizes to be awarded 

• Aviator Crown
• First Runner up
• Second Runner up

           Prizes worth INR 30,000 to be won.

• Participation certificates would be awarded to all the scholars who have registered.

Good Luck to Everyone!!!
