Dokładność i jakość wykonania elementów podwozia lotniczego ma bezpośredni wpływ na bezpieczeństwo ludzi podróżujących tym środkiem transportu. Szczególnie należy zwrócić uwagę na problemy z jakimi borykają się konstruktorzy i technolodzy podwozi związanymi z wymaganiami dotyczącymi zapewnieniu gwarantowanego poziomu niezawodności poszczególnych elementów. Oczywiście należy przy tym pamiętać o ergonomiczności i ekonomiczności procesu produkcyjnego. Obecnie najpopularniejsze z uwagi na niewątpliwe zalety jest rozwiązanie podwozia wielośladowe (trójkołowe) z przednim punktem podparcia. Zasadnicze obciążenie w tym podwoziu przejmują dwa główne koła umieszczone za środkiem ciężkości samolotu. Jego główne elementy tzw. STRUCTURAL POST mają szczególne zadania jeśli chodzi o bezpieczeństwo przewożonych ludzi. Stąd wysokie wymagania dotyczące jakości procesu produkcyjnego a w nim szczególnie newralgicznych jego operacji związanych z obróbką cieplną oraz prostowaniem przygotowującym do dalszej obróbki wykańczającej. W artykule zwrócono uwagę na towarzyszące procesowi bezpośredniego wytwarzania pomiary stanowiskowe, na podstawie których podejmowane są decyzje dotyczące kolejnych operacji.

The accuracy and quality of the chassis components of aircraft has a direct impact on the safety of people traveling in this means of transport. Especially pay attention to the problems with faced by engineers and technologists chassis associated with the requirements for ensuring a guaranteed level of reliability of the individual elements. Currently, the most popular due to the undoubted advantages has chassis tricycle with the front fulcrum. The principal load the chassis takes over the two main wheels positioned behind the center of gravity of the airplane. The main elements of the so-called POST STRUCTURAL, have the specific tasks when it comes to the safety of the people. Hence the high quality requirements of the production process associated with the heat treatment and straightening to the further finishing. The article focuses on accompanying in the manufacturing process of direct determine the measurements of bench based on which subsequent operations are undertaken.

High quality of components used in constructions of Landing Gears forces the manufacturers to choose appropriate technologies in order to manufacture and control dimensions of particular details. It is especially difficult to predict how the elements of huge dimensions will act during heat treat and chemical processing. The changes in size and. shape of the elements of suspension of STRUCTURAL POST aircraft are connected with hardening stresses. This requires accurate determining of allowance of final machining. The analysis of processing parameters and manufacturing of a precise component is possible with the use of high-tech coordinate measuring techniques based on touch and untouched measurements . The highest quality of machines used in manufacturing and measuring as well as innovative technologies used during the process of manufacturing STRUCTURAL POST components result in effects assumed by the designing engineer. The aim of this article is to present issues connected with technological process of manufacturing STRUCTURAL POST components as well as the analysis of particular parameters of manufacturing process which have an impact on the accuracy of dimensions and shape of the final product. These parameters are also responsible for functionality, operational reliability and safety of the Landing Gear.

Manufacturing of aircraft engine turbine blades requires control of blade geometric parameters at different stages of technological process. Acceleration and automation of measurement process can affect the duration of the finished item production. Modern technologies for measurement of aircraft engine turbine blades are based on numerical machines - measurement process is based on processing of numerical data obtained by measurement using coordinate measuring machines. The paper presents the opportunity of automation of aircraft engine turbine blades measurements using scanner ATOS II Triple Scan with blue light source technology. Coordinate measuring technique allows to specify full methodology for designation of complex dimensions of physical objects and transform them into a computer program space of coordinate measuring devices. Presented paper includes capabilities of device used in the study to improve the measurement process in the technological and economical aspects. Another issue described in the paper is impact of measurement performance in automatic mode on the quality of performance – the numerical model of surface, from the standpoint of accuracy and number of collected data points in time. The paper includes an analysis of conditions related to the measurement works, such as the process of preparing the model, measurement equipment and data processing capacity. As the result methodology for automated scanning measurements of aircraft engine turbine blades will be presented.
