Final Product: A full Carbon Rocket

The Full Carbon Rocket

This post aims at showing the final configuration of the rocket giving insight in the details of many subsystems previously not explained.

The electronics part was contained in the upper section. However it had to be linked to the parachute bay in order to trigger the pyro charge. Another important detail was the placement of the switches so that they could be turned on and off from the outside of the rocket. A bulkhead was placed on top of the parachute bay; this had a hole to allow the connection with the pyro charge and it had a bolt on which the stage structure could be screwed on. In addition a metal ring was glued on top of the bulkhead to allow for the switches to be placed on; in this manner a small chamber between the middle and the upper section was created to host the cabling and the switches.

Stage Structure, Electronics and wiring

One of the most challenging parts of the manufacturing phase was the soldering and cabling of the electronics. Some mistakes were done during the production: the individual bulkheads hosting the boards and the pressure sensor had to be put together after the soldering; an insulating layer on each bulkhead had to be applied to avoid short cuts; more space had to be dedicated to the wiring and longer wires could have been implemented.
Even though we were not experienced in this field at the end the electronics systems did not present any issue.

Introduction to the Small Rocket Project (SRP)

The small rocket project is a project for bachelor students of engineering faculties at TU Delft who wants to have practical experience in building an amateur rocket. The project is every year organized by the senior members of DARE ( Delft Aerospace Rocket Society ). Students who wants to take part in the project are divided in teams; the ultimate mission of every team is the following: "Launching a small rocket able to reach about 1000 meters of altitude mounting an egg as a payload and recovering it intact". On top of gaining practical experience, experiencing the full cycle design of a rocket and improving team working skills, the SRP gives young students the chance of getting to know the rocket society, their team leaders and the project carried out in the society. The WBPP team at work at the military base of 'T Hard Students experience a full cycle engineering design from the conceptual design, to testing and finally to the launch of the rocket. Teams ...

Pressure Sensor and Python Simulations

As mentioned in the post "Requirement Analysis and Conceptual Design", the rocket had to mount a pressure sensor in order to accurately measure the altitude at which the parachute had to be deployed. In fact the board provided by the electronic team of DARE alone had a timer only; using the timer only to deploy the parachute would have meant trusting completely the simulations done on Open Rocket. However those simulations do not take account of the actual density and pressure at the launch site, the wind speed and direction. For this reason a pressure sensor was used to deploy the parachute exactly at the altitude needed. Hardware An Arduino Nano and a BMP 180 pressure sensor were purchased; because the pressure sensor was an Adafruit product the library had to be imported in order to read the measurement from the pressure sensor. The wiring is very easy and it can be found in many Adafruit guides. The hardest part was to allocate some space for the wires in the stage ...
