IREC 2021
​BLACKOUT 

​Current Status: Completed, ranked 17th
Picture

Project Overview

Blackout is a level 3 high-powered rocket competing in the 10,000 AGL apogee COTS category at the 2021 Intercollegiate Rocket Engineering Competition (IREC). The rocket is a 10.5 ft. completely custom carbon fiber aero-structure and SRAD flight computer equipped with an M-2020 75mm Cesaroni solid motor.

Nose Cone

A 4:1 6” tangent ogive nose cone was chosen as the team has had previous success with this similar shape in previous rockets. Our nose cone is 35” long, made in house using carbon fiber, with a machined tip for more control over the tip radius and strength, compared to the conventional solid carbon fiber tip with a larger tip radius.

Structure 

The purpose of the body tubes is to house the inner components of the rocket while providing aerodynamic stability throughout the flight.  For the IREC 2021 rocket, the following unique considerations were made:
  • Carbon fiber body tube 
  • Carbon fiber boat tail 
  • Carbon fiber nose cone
The body tubes were constructed through a carbon fiber wrap process using an X-Winder filament winding machine and 3K carbon fiber tow. This is done by winding carbon fiber around a mandrel, wrapping nylon release peel ply on top, then later peeling off the ply and removing the tube from the mandrel.

Booster

The lower section of the rocket, the booster, has multiple parts: motor retainer, fin can, and main parachute. The main goals of the booster are to secure and center the motor and motor casing.
The motor retainer is a two-piece design:
  • “Bulkhead” piece is epoxied to the very bottom of the rocket 
  • “Retainer” piece is secured to Bulkhead using 8 fasteners 
​The fin can utilize a 3D Printed design that will “clamp” onto fins machined from carbon fiber sheets from DragonPlate during installation using an interference fit. The assembly is not meant to be load bearing and is only for alignment purposes.

Avionics 

The deployment of the main parachute is handled by the Eggtimer Quark with a Stratologger PerfectFlite as redundancy. For data collection, a custom flight computer (S.P.I.C.A.) was designed to obtain telemetry for the rocket as well as to detect apogee. Telemetry for the rocket includes pressure, temperature, altitude, acceleration, pitch, roll, yaw, and GPS position. To obtain pressure, temperature, and altitude, two different altimeters are used with a max measurable altitude of 120,000 feet. To obtain acceleration, pitch, roll, and yaw, a 9 Degree-of-Freedom Inertial Measurement Unit (IMU) is implemented with an additional 100G 3-axis linear accelerometer. For tracking purposes, a GPS module with an additional active antenna is used. Telemetry for the rocket is stored on the S.P.I.C.A. using a SPI Flash memory chip, and data is also transmitted in real-time with a 900MHz transceiver. While not used until further testing is performed, the S.P.I.C.A. also has four deployment channels with continuity sensing. Since the airframe is made of carbon fiber, an RF-blocking material, external antennas are mounted to the outside of the rocket for the 900MHz transceiver and the GPS. 

Camera & Switches 

Another unique part of this years rocket is ​the mechanical arming switches and the embedded cameras.
The four RunCam Split 3s cameras are mounted in an enclosure inside the rocket to reduce aerodynamic drag while still getting a good view while capturing footage at 1080p and 60fps.

The Remove Before Flight (RBF) pins allow arming and disarming of the rocket by pull-pins on the pad. Theses custom switches, manufactured by Jim Heaney, give the team fast, reliable, inexpensive, and reversible arming switches.

Payload

This year we put together a fun and small experimental payload. From our local brewery, two Genesee beers were secured in a plywood and steel payload housing and attached via recovery hardness to a secured bulkhead. The goal of this payload is to test temperature fluctuation from initial liftoff, apogee, and landing.
