Впровадження DO-254 в процес розробки регуляторів авіадвигунів

Abstract

The experience of JSC Element, a certified developer and manufacturer of components for aviation equipment, is described in terms of introduction into the product development process, namely, their hardware, the requirements and recommendations of the RTSA DO-254 avionics design assurance manual, similarly earlier implemented RTSA DO-178 for the firmware of said products. The need to introduce these documents developed by the Radio Technical Commission for Aeronautics is due to the desire of domestic developers and manufacturers of aircraft products to integrate into the system of international cooperation in the field of aircraft manufacturing. Brief results of the comparison of the requirements of DO-254 with the requirements of the national standard DSTU 3974–2000 for development in terms of the sequence of stages and the content of work are given. It is shown that, working in accordance with the requirements of the current domestic system of standards, Ukrainian development enterprises (including Element JSC) sufficiently ensure the completeness of the passage of what is called in the implemented Guide DO-254 "life cycle of hardware design" and that the main differences are in the form of documentation of development processes and results. Differences in the concept of planning according to DO-254 and in domestic practice are considered, and analogies are redrawn between plans in the interpretation of DO-254 and documents traditional for the system of domestic standards. In terms of the practical development of the forms and methods for documenting the life cycle processes of the development of onboard equipment, the company JSC "Element" is currently at the initial stage, introducing them for the first in the development of the RDC-450M-117V regulator for the aircraft engine TV3-117VMA-SBM1V. The prospects for the work of the enterprise in this direction are outlined, including the integration of the requirements and recommendations of DO-254 into the system of enterprise standards operating within the framework of a certified quality management system.
