aircraft.
1.1 Introduction:
It’s your time now to change the maneuver history to
fly the smallest bomber plane at the lowest altitude.
1.2 Problem

freedom including yaw, pitch and roll and that can complete a specified path
and drop a packet of given weight at some specified location in the minimum
possible time.

Machine Specifications:
3.1
Glider Specifications
1. An aircraft is defined as an object that has the four
forces of flight, namely lift, drag, weight (gravity) and thrust due to
propeller acting on it at any point of time.
2. The aircraft is to be designed in such a way that it
can carry a packet (block) of 70-75gms, and can release it midway during its
flight.
3. The Block will be a solid block of dimension 50mm x
30mm x 18 mm. No additional carrying feature such as hooks etc. will be
provided with the block. However, participants are expected to devise their own
slot, hook or any other mechanism to carry and dispatch the block. Mechanism,
wherein some part of the aircraft also gets dropped with the packet is also
allowed.
4. The use of launching mechanisms is prohibited. The
aircraft should be hand launched. At the time of launching there must be some
mechanism to accommodate the packet.
5. The use of IC engines is prohibited. Only electrical
motors are allowed.
6. The participants are free to use the materials of
their choice. However the use of Balsa wood or foam (sun board) or sun pack is
advisable. Balsa wood is light, easy to handle and fabricate the Aircraft
making it the best choice.
7. Participants must make all parts of the aircraft
themselves. Usage of Ready-to-Fly (RTF) and Almost-Ready-to-Fly (ARF) kits is
strictly prohibited. However, the kit comprising of unassembled cut-pieces of
Balsa wood is allowed. Also use of readymade actuators/motors, remote controls
and propellers is allowed. Refer to figure 1 and 2.
8. Use of gyroscopes (gyros) is prohibited.
9. If
anyone found not following above rules will be disqualified
3.2
Judging of Design
1. Designing of an aircraft is a very important part of
this competition. The tasks in competition include aerobatics, sharp turns,
accurate dropping off the payload and speed. So your aircraft should be such
that it can perform the given tasks effectively. The tasks for the competition
are:
a. Aerobatics
(maneuvering).
b. Packet
Dropping
c. Safe
landing.
d. Flying as
fast as you can in addition to taking sharp turns to complete the run in
minimum possible time.
2. Each entry will be judged before the start of the
task. The judging will be based on the following criteria:
a.
Functionality of Design.
b. Innovation
of Design.
3.
There will also be prizes for Best Design, Innovative Design, etc. which will
be announced later. But these prizes will be awarded depending on your
performance of your aircraft in round 1 (qualification round).
Rules:
4.1
Competition Rules
Round
1:
1. In this round participant has to hand launch the
aircraft from the launching zone and has to perform the following maneuvers:
a. Square circuit: The participant has to
make a square shaped circuit in air.
b. Vertical loop: The aircraft has to make a
vertical loop.
c. Roll: The aircraft must perform a complete
360 degree roll.
2. The maneuvers will be subjectively judged. The
performance of a team in Round 1 will determine its selection for Round 2.
Since we have subjective judging, completion of even one maneuver out of these
three may get you selected for the next round.
3. A maximum time of 2 minutes per run will be given to
perform these moves.
4. The participants will be given 2 runs to perform these
tasks.
5. The aircraft has to be hand launched from launching
zone which is behind the finish line.
6. The
participants will be allowed a total of 3 chances to launch the aircraft in
every run i.e. if the aircraft doesn't fall out of the launching zone in an
attempt to launch it, then they can re-launch their aircraft.
Round 2
In this
round the participant has to launch the aircraft from a specified launching
zone.
1. Launching zone is a circle of radius 10m.
2. Participant has to accommodate the packet (dimensions,
weight and figure given below) in the aircraft while launching.
3. A run will be considered complete if the aircraft
crosses the launching zone, completes the task along the way and lands after
the finish line.
4. A safe landing will be given special credits in
scoring (see judging criteria). For instance if during landing, the fuselage of
the aircraft breaks, then points for safe landing will not be awarded to the
team. Safe Landing will be judged subjectively.
5. The time of flight for a run is defined as the time
taken by the aircraft to finish the tasks given, reach the finish line and
land.
6. The timer will start from the moment the aircraft is
hand launched and is in the air.
7. The timer will stop only when the aircraft finally
comes to a halt.
8. If in any run the aircraft does not complete the tasks
at hand in the order in which they're meant to be followed, the run will not be
awarded any points.
9. The participants will be allowed a total of 3 chances
to launch the aircraft in every run i.e. if the aircraft doesn't fall out of
the launching zone in an attempt to launch it, then they can re-launch their
aircraft.
10. Participants will be given maximum of 4 minutes to
complete Round 2 from launching of aircraft to landing. If participant fails to
complete the task in 4 minutes then no Time points, PT (see scoring) will be
awarded.
11. The
aircraft will be judged on the basis of time of flight, accuracy in dropping,
safe landing, weight of the craft and dimensions of the craft.
4.2
Path for Round 2
The
total task of aircraft is to launch, complete the task and then land. The path
here is given point wise:
·
Step 1: The aircraft will be launched from
launching zone.
·
Step 2: It reaches the end of the arena takes
a U turn.
· Step 3: It transects the plane containing
pole 1 and pole 2 below the ribbon and then takes a turn and transects the
plane containing pole 2 and pole 3 above the ribbon (see arena).
· Step 4: After crossing pole 3, it should move
forward and transect the plane containing pole 4 and pole 5 below the ribbon
and drop the packet in the drop zone. The aircraft can fly below this ribbon at
most 2 times. Dropping and crossing of plane below the ribbon need not to be
simultaneous.
·
Step 5: Then it must cross the plane between
pole 6 and 7.
·
Step 4: It should then return back to the
finish line and land safely.
Points
for dropping will only be given if the aircraft completes the specified maneuvering
and doesn’t touch the ground at any instance before dropping.
If the
aircraft touches the ground after dropping and before reaching the finish line,
then Time points (PT) and points for safe landing will not be awarded.
Participants
are allowed to devise some mechanism wherein some part of the aircraft also
gets dropped with the provided weight.
The
timer will stop only when the plane has returned back to the finish line and
came to a halt.
4.3
General Rules:
1. The teams must adhere to the spirit of healthy
competition. The teams must not damage the opponent's aircraft in any way.
Judges reserve the right to disqualify any team indulging in misbehavior.
2. Any team that is not ready at the time specified will
be disqualified from the competition automatically.
3. The aircraft would be checked for its safety before

organizers reserve all rights to change any or all of the above rules as they
deem fit. Change in any rule, will be highlighted on the website.
