Abstract

U radu je opisan postupak izrade bespilotne letjelice. Cilj je projektiranje bespilotne letjelice i provođenje računske potvrde o njezinim performansama. Ovaj pristup omogućava studentima upoznavanje s osnovama gradnje letjelice te rješavanje konstruktivnih i aerodinamičkih problema tijekom izrade. Za izradu letjelice korištena je kompozitna struktura koja je zahtjevnija s obzirom na proces proizvodnje. Proces započinje s idejom koja se dokazuje proračunom aerodinamičkih karakteristika i osnovnih performansi zrakoplova uz testiranje prototipa. Model letjelice upravljan je preko radio frekvencijskog uređaja. Za pogon letjelice korišten je elektro-ventilatorski motor koji može imati sustav naknadnoga izgaranja zapaljivog plina te servomotori za upravljanje komandnim površinama. Dobivene performanse su zadovoljavajuće uz maksimalnu brzinu horizontalnoga leta od 25 m/s jer da letjelica ima malu i slabu pogonsku grupu. Izračunate performanse uspoređene su s rezultatima dobivenim testiranjem slobodno letećeg modela pri čemu je bitno uzeti u obzir faktor točnosti izrade modela.

Abstract (english)

In this paper is a description on how to make an unmaned aircraft vehicle. The goal of this project is to design and mathematically verify a model plane performance. This allows for students to familiarize with basics of building an aircraft and resolving structural and aerodynamic problems. Composite materials are used for the structure, this tipe of material is most complex due to it's manufacturing process. In building a plane, the proces begins with an idea wich is matemathically tested. After that follows the free flying model test wich is used for canceling all problem for the build of the finall product. The aircraft is controlled via remote controll. The powerplant is an electric ducted fan motor with possible afterburning butane gas to increase thrust. The performance of this aircraft are relatively good with a maximum speed of 25 m/s since it's a small aircraft with a small and weak powerplant. After geting the mathematicall performance they are compared with real performance given in the flight of the aircraft.
