Havoc

2014
Orange

Team Havoc was formed in response to the 2014 Speedfest IV competition.  The team composed of 21 students majoring in Aerospace Engineering at Oklahoma State University and the competition served as their senior design project.  Over the course of about three months, the team produced four pylon racers, three gliders, and three parachute pods.  The Speedfest IV competition consisted of two missions.  The first mission involved climbing and releasing the payload, a golfball, within ten seconds.  The payload descent time then determined the allowable time to complete mission two. The rules allowed for the design of a Payload Descent Vehicle to maximize the payload descent time, and the maximum allowable payload descent time was three minutes.  Team Havoc decided on a modular design, allowing for the use of either a glider or a parachute pod for the Payload Descent Vehicle.  The second mission was to complete as many figure-8 laps as possible on a 600 ft pylon course within the payload decent time.  The score equaled the number of pylons passed during mission 2.  In the event of a tie, the teams had to perform mission 2 with the mission 1 configuration that gave the team the tie score.

Contest Summary: 

Speedfest IV Rules

Mission 1: Payload Drop

The aircraft has ten seconds to climb into the designated area east of runway and drop the payload. The payload descent time (PDT) begins from payload release and ends when the payload hits the ground or is out of judges sight. The PDT has a maximum of three minutes. The run is disqualified if the payload is not fully separated at the ten second buzzer or the payload lands outside of the designated area.

Mission 2: Pylon Race

The time begins after the signal to enter the course when the plane reaches the first turn line and the time ends at the PDT. Fly figure 8’s with a flag being raised at each turn. Score: Total number of turn flags raised within PDT.

Tie-Breaker Mission

The tiebreaker mission will be flown in full mission 1 configuration. The complete payload descent system must remain with the aircraft during the entire flight. The mission 1 configuration used must be the same as the mission 1 configuration that generated the highest mission 2 score if multiple configurations were used. The mission and scoring for the tiebreaker will be the same as mission 2 which is to fly as many figure 8’s as possible in 3 minutes.
