Rotorcraft (kapena ndege yamapiko ozungulira)

Rotorcraft (kapena ndege yamapiko ozungulira) ndi yolemera kuposa ndege yomwe imagwiritsa ntchito kukweza kopangidwa ndi mapiko, otchedwa rotor blades, yomwe imazungulira pamtengo. Ma rotor angapo omwe amaikidwa pamtengo umodzi amatchedwa rotor. International Civil Aviation Organisation (ICAO) imatanthawuza rotorcraft yomwe imathandizidwa pakuwuluka ndi momwe mpweya umayendera pa rotor imodzi kapena zingapo.

Popeza rotor ya rotorcraft ilibe mphamvu, ilibe kugwedezeka kwakukulu ndi phokoso lopangidwa ndi makina oyendetsa magetsi. Kugwedezeka uku ndi phokoso sikudzafupikitsa kapena kuonjezera moyo wa utumiki wa rotor, thupi, ndi zina zotero. Zomwe zimachitika chifukwa cha makina oyendetsa mphamvu a rotorcraft mwachiwonekere ndizochepa kwambiri.

Gyrocopter imatha kusintha zokha kuti fuselage ikhale ndi kukhazikika kwabwino, kukhazikika kwa mpukutu ndi kukhazikika kwa liwiro. Disiki yozungulira ya propeller ili ngati gudumu lalikulu la inertial, ndipo rotor ilibe kusintha kwanthawi ndi nthawi. Kuphatikiza apo, mbali yoyika rotor ndi yayikulu kuposa ya helikopita, yomwe imakhala ndi zotsatira zabwino za gyroscopic, kukhazikika kwapamwamba komanso kukana kwamphamvu kwa mphepo.
