Abstract

U ovom radu analiziran je princip rada akumulatora. Detaljno su razrađene najčešće izvedbe akumulatora u zrakoplovu te su objašnjena konstrukcijska rješenja. Mjerenja unutarnjeg otpora su prikazana na primjeru olovnih akumulatora koji se koriste u zrakoplovu Cessna 172 i Diamond DV20. Rezultati su pokazali da Cessnin akumulator ima manji unutarnji otpor, točnije 0,015 Ω, a Diamondov 0,051 Ω. Analizom je utvrđeno da akumulator zrakoplova Diamond DV20 ima veću sklonost samopražnjenju.

Abstract (english)

This paper examines the operating principle of batteries. The most common aircraft battery designs are thoroughly discussed, and their structural solutions are explained. Measurements of internal resistance are demonstrated using the example of lead-acid batteries used in the Cessna 172 and Diamond DV20 aircraft. The results indicate that the Cessna battery has significantly lower internal resistance. It has a resistance of 0,015 Ω and the Diamond battery has 0,051 Ω. The analysis revealed... More that the battery from the Diamond DV20 aircraft exhibits higher self-discharge tendency. Less
