Kompaktni analizator leta modelarske rakete

Pogačnik, Luka (author), Jankovec, Marko (mentor)

V okviru tega magistrskega dela sem izdelal kompaktni analizator leta za modelarske rakete. Pred izbiro komponent ter tehnologij, sem najprej preučil vse možnosti, nato pa izbral najprimernejše in izdelal svojo napravo. Z velikostjo 16 mm x 31,5 mm x 9,5 mm ter maso 4,3 g se moj analizator leta uvršča med najkompaktnejše, z vgrajenim zaslonom, Li-Ion baterijo, povezljivostjo prek USB in merilci pritiska, pospeška ter relativnega zasuka. Po funkcionalnosti se uvršča tudi med najzmogljivejše analizatorje leta na tržišču. Z vzorčno frekvenco 75 Hz za tlak ter 833 Hz za pospešek ter rotacijo ima na vgrajenem spominu dovolj, prostora za več kot 600 s meritev, iz katerih je zaradi visoke vzorčne frekvence mogoče razbrati dogajanje med letom.

Abstract

The goal of this master's thesis was to develop a compact flight analyser for use in model rockets. Before choosing components and technologies, I first studied all available options and then choose the most appropriate ones for my device. With the size of 16 mm x 31,5 mm x 9,5 mm and weight of 4,3 g, my flight analyser positions itself among the most compact ones, that have integrated display, Li-Ion battery, USB connectivity and sensors for pressure, acceleration and rotation. By functionality it is one of the best flight analysers on the market. It boasts sampling frequency of 75 Hz for barometer and 833 Hz for accelerometer and gyroscope. It has enough storage for over 600 s of measurements, which, due to high sample rate, allows for an insight into what happened during flight.
