profession with 3 lanes
Opis:: This paper deals with development of application software for supporting the administration and management of professional trees on an automobile assembly industry. The standard qualifications that are introduced in this paper called the profession with 3 lanes (P3L). Each profession tree is assumed can have 3 lanes that have equality, namely operator/technician lane, utilizer lane, and manager lane. The lanes are graded equally, similar in difficulty and similar in appreciation. An operator lane is focused on operating of machines/ equipment/ methods/ programs. The main consideration of this lane is at the skill aspects. A utilizer lane is focused at the utilizing of main and supporting equipments. The main consideration of this lane is the analytical aspects. The last, a manager lane is focused at the management of jobs. The main consideration of this lane is at the coordination of finishing the jobs. The application software has been developed to support the administration of the concept that has been applied on an automobile assembly industry. Basically, the application consists of two main parts that are a database and the user interface. By using this software, the administration and management of all professions as well as their competencies can be done easily.

Opis:: The paper discloses the analysis of processes that take place during the start-up operation of the driving unit for the training aircraft of the TZL-130 TC-II Turbo-Orlik type. The aircraft is designed for selective and initial trainings at the Air Force School of “Little Eagles” in Dęblin. The driving unit comprises the PT6A-25C turbo-propeller engine from Pratt & Whitney combined with the four-bladed airscrew from Hatzell. It is specifically mentioned that data for the analysis were sourced from the S2-3a on-board recorder of flight parameters manufactured by the Air Force Institute of Technology (AFIT). The analysis was carried out both during ground and flight tests. The paper briefly outlines general structures and operation principles of typical start-up systems with the focus to their key components. Attention is paid to how important it is to select an appropriate start-up system to match the specific aircraft type and the guideline parameters for selection that should be adhered to are specified. Also there are disclosed the key mathematical relationships that are indispensable to design start-up systems and to find out their basic characteristics. It is emphasized that the start-up operation must be considered as a non-stationary process that lasts from the standstill state of the engine until the moment when the minimum required rpm is reached, sufficient to generate necessary power of the engine. In addition, the attention is paid to the fact that the value of the engine acceleration is crucial to the achievable start-up time that is deemed as one of key parameters for all start-up systems. It is demonstrated that to achieve the required level of acceleration, it is necessary to secure the so called overhead of the engine power which needs constant flow offuel and air into the combustion chamber of the engine. The last part of the paper comprises selected characteristic curves that were obtained from the analysis of the engine start-up processes both on ground and in flight. The final conclusions emphasize that the start-up system for the presented driving unit is really efficient and guarantees correct operation of the engine under any conditions.

Tytuł:: Use of data from on-board data recorders for acceptance tests of avionic driving units

qualification tests for avionic driving units
Opis:: The paper explains how information stored in on-board recorders of flight parameters can be used for acceptance tests, also referred to as qualification tests. The disclosed example refers to the An-28 ‘Bryza’ aircraft where an old airscrew was substituted with the new generation Hartzell airscrew of the HC-B5 MP-3D type. The airscrew is an integral part of the driving system for the airscrew propelled aircraft that is provided with the TWD-10B engine. After revamping of the airscrew, the aircraft was named as TWD-10B/PZL-10S. The follow-up investigations were carried out with the aim to find out how much the airscrew substitution affected the alteration of key performance characteristics achieved by the driving unit of the aircraft. The investigations comprised both ground and in-flight tests and have led to determination of the essential characteristics for the engine operation as well as variations of the operational parameters in time. In some cases also so called phase portraits were found out for parameters of the engine operation so that to reflect dynamic properties of the engines. Such investigations are indispensable since the aircrafts are subject to operational limitations and technical conditions that must be mandatory fulfilled due to requirements of flight safety. The paper demonstrates that the data stored in on-board recorders of flight parameters can be really useful for execution of such acceptance (qualification) tests.
