Abstract

Determination of the geometry of aircraft surfaces has always been an extremely complicated task, though it is very important for the aerodynamic properties of the entire aircraft or its parts (like wings, body, rudders, etc.). Measurement of the geometrical properties of aircraft parts is especially difficult due to the smoothness of their surfaces. Here in this paper a short review of two methods of determining the shape of aircraft parts are given: one relies on determining point position by means of laser‐based scanning and another relies on photogrammetry. A comparison of the results of both methods applied to the same aircraft element is also presented.


Santrauka


Orlaivio paviršiaus geometrijos nustatymas visada buvo labai sudetinga užduotis, nors tai labai svarbu orlaivio daliu (sparnu, liemens, vairu ir kt.) ar viso orlaivio aerodinaminiu charakteristiku kontrolei. Nustatyti geometriniu orlaivio detaliu matmenis yra ypač sudetinga del jū lygaus paviršiaus. Šiame straipsnyje trumpai aprašyti du orlaivio daliu paviršiaus formos nustatymo metodai: vienas remiasi tašku koordinačiu nustatymu naudojant lazerinio skenavimo tipo matavimus, kitas ‐ fotogrametrinius matavimus. Taip pat pateiktas abiej u metodu palyginimas taikant juos to paties orlaivio elemento formos nustatymui.
