Inter College Rocket Competition

Inter College Rocket Competition

Contest Rule

Competition Description

The competition is in four phases. Phase one in is the application phase. Teams must submit an application and a 10000 INR competition fee that is non-refundable. The fee is used to offset the cost of materials. Applications must be submitted before JANUARY 20, 2017. Phase two is the preliminary design. Teams are to develop designs, prototype, test concepts and generate a preliminary design review (PDR) slide package using the provided template. Teams will submit PDR slides in only PDF format at the designated due date. Teams that do not meet the due date or do not submit in the proper PDF format will be dropped from the competition. A schedule will be made available on when to present a subset of the slides. Teams will have a half hour to discuss a subset of the PDR slides via telecon. Phase three is the critical design. Teams will finalize their design and start ordering components, manufacturing parts, test subsystems and start developing the flight unit. Teams will generate a critical design review (CDR) slide package using the provided template. Teams will submit CDR slides in only PDF format at the designated due date. Teams that do not meet the due date or do not submit in the proper PDF format will be dropped from the competition. A schedule will be made available on when to present a subset of the slides. Teams will have a half hour to discuss a subset of the CDR slides via telecon. After PDR, selected teams will be invited to the final competition. Phase four is the launch weekend and SDNx will be responsible for security clearance and permissions. Certificate will be given to all participants and T-shirts will be given to the team who have selected for final launch.


All rockets must be built and flown in accordance with the Model Rocket Safety Code of Space Development Nexus, any applicable local fire regulations, and Air Traffic control (ATC). Rockets flown at the Finals must have previously flown safely and successfully. Rockets will be inspected before launch and observed during flight by SDNx and Space officials, whose judgment on their compliance with the Safety Code and with these rules will be final. Teams are encouraged to consult with SDNx officials who are running this event well before the fly-off to resolve any questions about design, the Safety Code, or these rules.


The application for a team must come from a single college or a single Indian non-profit youth or educational organization There is no limit to the number of teams that may be entered from any single school or organization, but no more seven members in a team containing students who attend the same college or who are members of the same organization, regardless of whether the teams are sponsored by that college or organization, can be invited to attend the Finals. Team members must be students who are currently enrolled in 2nd year and above semester in engineering or Science College. Teams may have members from other colleges or other organizations and may obtain financing from any source, not limited to their sponsoring organization. Teams must be supervised by a supervisor guide approved by the principal of the sponsoring college, or by an officially-appointed competent person of their sponsoring organization. Minimum team size is three students and maximum is six students. Each student member must make a significant contribution to the designing, building, and/or launching of the team's entry. No part of any of these activities for a rocket used in a qualification flight or at the Finals may be done by any adult, by a company (except by the sale of standard off-theshelf components available to the general public, but not kits or designs for the event), or by any person not a student on that team. No student may be on more than one team. The supervising teacher/adult may supervise more than one team. The Challenge is open to the first 1000 teams that submit a completed application, including payment.


Rockets must not exceed 3500 grams gross weight at liftoff. The smaller-diameter of the two must be used for the lower (motor and fin) end of the rocket and must not be greater than 65 in diameter, and the larger one must be large enough to contain water balloon (which may be up to 50 millimeters) plus padding and altimeter. Each tube must have no less than 150 millimeters (5.91 inches) of exposed length, and the overall length of the rocket must be no less than 650 millimeters (25.6 inches) as measured from the lowest to the highest points of the airframe structure in launch configuration. Rockets may not be commercially-made kits designed to carry water balloon payloads with the only modification being the addition of an altimeter compartment. They must have only one stage. They must be powered only by self Designed and Manufactured - Rocket Motors (Exclusively KNSU Propellant) of "J" or lower power. Any number of motors may be used, but the motors used must not contain a combined total of more than 640 Newton-seconds of total impulse. Rockets must not contain any pyrotechnic charges except those provided as part of the basic commercially-made rocket motor used for the flight, and these must be used only in the manner prescribed in the instructions for that motor. The rocket must separate into at least two pieces for recovery, with one piece containing the water balloon payload and the altimeter and not the expended rocket motor. This piece must be recovered by a single parachute and must not be connected in any manner to the other piece or pieces of the rocket during recovery. The rest of the rocket may use any safe means of recovery. All rockets flown at the Finals must have a surface finish with a different color or colors than the basic construction materials of the rocket which has been applied over all or most of the outer surface of the rocket's nose, body, and fins by means such as paint, ink, adhesive wraps, etc.


Rockets must contain and completely enclose one water balloon of 55 to 61 grams weight and must return it from the flight without any burst or other external damage. The water balloon will be issued to the teams by event officials during the qualifying flights & finals. The water balloon and altimeter must be removed from the rocket at the end of the flight in the presence of a SDNX Team Officials and presented to that official, who will inspect the water balloon for damage after their removal and will read the altimeter score. All coatings, padding, or other materials used to protect the water balloon must be removed by the team prior to this inspection. Any external damage to the payload noted after its flight and removal from the rocket by the team is disqualifying.

Avionics Bay

Avionics Bay Should comprise of compulsory subsystems: Telemetry System, GPS made by GARMIN, CMOS Pinhole camera. Telemetry system should live transmit the Flight parameters down to the Ground Station of TABLET / Android Phone or Laptop.


The duration score for each flight shall be based on total flight duration of the portion of the rocket containing the water balloon and altimeter, measured from first motion at liftoff from the launch pad until the moment that the first part of that portion of the rocket touches the ground (or a tree) or until it can no longer be seen due to distance or to an obstacle. Times must be measured independently by two people not on the team, one of whom is the official SDNx-member adult observer, using separate electronic stopwatches that are accurate to 0.01 seconds. The official duration will be the average of the two times, rounded to the nearest 0.01 second, with .005 seconds being rounded up to the next highest 0.01 seconds. If one stopwatch malfunctions, the remaining single time will be used. The flight duration goal is a range of 41 to 43 seconds. Flights with duration in the range of 41 to 43 seconds get a perfect duration score of zero. Duration scores for flights with duration below 41 seconds will be computed by taking the absolute difference between 41 seconds and the measured average flight duration to the nearest 1/100 second and multiplying this by 4. Duration scores for flights with durations above 43 seconds will be computed by taking the absolute difference between 43 seconds and the measured average flight duration to the nearest 1/100 second and multiplying this by 4. These duration scores are always a positive number or zero. For those teams at the Finals that are invited to make a second flight based on their first-flight performance, the target duration for the second flight at that event will be 42 to 44 seconds and scoring for flights with durations above or below this range will be aligned to match the procedures for the 41-43 second range.


Rockets must contain one GPS Transmitter or electronic altimeter, CMOS PINHOLE Camera, commercial types approved for use in the Rocket Launch Competition. The altimeter must be inspected by an SDNx official both before and after the flight, and may not be modified in any manner. The altimeter must be confirmed by this official before flight to not have been triggered and to be ready for flight. The peak altitude of the rocket as recorded by this altimeter and sounded or flashed out on its audible or visible light transmission post-flight will be the sole basis for judging the altitude score and this altimeter may be used for no other purpose. Other altimeters of other types may be used for flight control or other purposes. The altitude scores for every qualification flight and for the first flight at the Finals will be the absolute difference in feet between the 3300 feet (1000 meters) target altitude and the altimeter-reported actual flight altitude in meter (always a positive number or zero).


Team members cannot be changed after the first qualification flight, with one exception as noted below for the Finals. Only team members on record at SDNx with valid college consent forms are eligible to receive prizes. In order to be eligible for the national final fly-off event, a team is required to fly and submit the results from at least two qualifying flights observed in person by an adult (senior) member of the SDNx (unrelated to any team members or to the team's adult supervisor and not a paid employee of their College or member of their youth group). More than two qualification flights are not required if the team is satisfied with the results of their first two flights. A qualification flight attempt must be declared to the SDNx observer before the rocket's motor(s) are ignited. Once an attempt is declared, the results of that flight must be recorded and submitted to the AIA, even if the flight is unsuccessful. A rocket that departs the launch pad under rocket power is considered to have made a flight, even if all motors do not ignite.If a rocket experiences a rare "catastrophic" malfunction of a rocket motor, a replacement flight may be made, with a replacement vehicle if necessary. Flights which are otherwise fully safe and qualified but which result in no altimeter reading despite correct usage of the altimeter by the team, or that result in a reading of less than 50 feet despite a nominal flight will be counted as "no flight" and may be reflow without penalty. The results from qualification flight attempts must be faxed or scanned and e-mailed to and received at the offices of the SDNx by Date & Time. Based on these qualification scores 100 teams (with a limit of no more than the best three made up of students from any single College or organization) will be selected on the basis of lowest combined scores for their best two flights. If a College has more than three teams whose flight score is better than the cutoff score for Finals selection, they may adjust the membership of the three best teams invited to attend the Finals to include students from other teams with scores that met the Finals cutoff, up to a limit of ten students on any single team. Teams will be notified no _____date, and will be invited to participate in the final flyoff to be held on _____


Every portion of the rocket must return to earth safely, and at a velocity that presents no hazard. Any entry which has a heavy structural part (including but not limited to an expended engine casing) fall to earth with no recovery device attached will be disqualified. The portion of rocket containing the water balloon must be allowed to land at the end of flight without human intervention (catching) and will be disqualified if there is such intervention.


Return of the portion of the rocket containing the water balloon and altimeter is required by the deadline time on that same day that was established at the beginning of the day's flying. If the rocket cannot be returned after an otherwise safe and stable flight because it cannot be located or because it landed in a spot from which recovery would be hazardous (as determined by an SDNx official), a replacement vehicle may be substituted for a replacement flight. Once the SDNx official has declared that a rocket has landed in a place from which recovery would be hazardous, the results from that rocket's flight may not subsequently be used even if it is recovered.


Teams may use the electrical launch system and the launch pads (with six-foot long, 1-inch rails or 1/4inch diameter rods) provided by the event officials at the fly-off, or may provide their own system. Systems provided by teams for their own use must be inspected for safety by an SDNx official before use, and must provide at least 6 feet of rigid guidance, including use of a rod diameter of at least 1/4 inch, if a rod is used. All launches will be controlled by the event Range Safety Officer and must occur from the ground.


Rockets may not use an externally-generated signal such as radio or computer control (except GPS navigation satellite signals) for any purpose after liftoff. They may use autonomous onboard control systems to control any aspect of flight as long as these do not involve the use of pyrotechnic charges.


Places in the final fly-off of the competition will be determined on the basis of the sum of the altitude and duration scores. At the fly-offs, at least 24 teams will be invited to make a second flight based on the results of their first flights. Prizes awarded to the top places will be awarded only to those teams that make a second flight. The top final places will be ranked on the basis of the scores from the two qualified flights made at the fly-offs. Remaining places will be awarded based on the scores from the first flight. Ties will result in pooling and even splitting of the prizes for the affected place(s) -- for example, a two-way tie for 4th place would result in a merger and even division of the prizes for 4th and 5th places. If there is a tie for one of the top three places, the teams involved in the tie will be required to make a third flight to determine final places. SDNx reserves the right to make all last and final contest determinations. Other awards like best design and best stability award will be given.
