Abstract This paper investigates the software standard DO-278A from the RTCA according to assurance level 3 to provide a concept for approving software of ground-based navigation aids. For this purpose, related literature and standards were reviewed and evaluated for their applicability for proposing such a concept. The resulting approval concept shows our approach for conducting the development process according to DO-278A based on a traditional one and focusing on an activity schedule. Therefore, the paper offers preliminary considerations at first to show the relation between system and software development. In addition, corresponding standards that are related to the development are presented as well. The concept is segmented in three main phases for software planning, realization, and verification, which are subdivided and scheduled in specific activities. Each activity consists of an outline describing the contents expected by DO-278A and our approach to organizing them. This paper shows our conceptional approach to obtain an approval for software according to DO-278A. This concept is prepared to approve a radio navigation aid.
摘要:本文根据保证等级3对RTCA的软件标准DO-278A进行了研究,为陆基助航软件的审批提供了一个概念。为此,对相关文献和标准进行了回顾和评估,以确定其是否适用于提出这一概念。由此产生的批准概念显示了我们根据DO-278A进行开发过程的方法,该方法基于传统的DO-278A并专注于活动时间表。因此,本文首先对系统与软件开发之间的关系进行了初步的探讨。此外,还提出了与开发相关的相应标准。这个概念被划分为软件计划、实现和验证的三个主要阶段,这些阶段被细分并安排在具体的活动中。每个活动都包含一个大纲,描述DO-278A期望的内容以及我们组织这些内容的方法。本文展示了我们根据DO-278A获得软件批准的概念方法。这个概念是准备批准一个无线电导航设备。

Abstract To meet the needs of the airborne dispenser to disperse large-mass bullets, the dispersal system of large-size gasbag with multiple inlet nozzles was designed and built. The rationality and feasibility of the dispersal system were verified by the experimental study of the interior ballistic process. On this basis, the fluid–structure interaction method was used to simulate and analyze the process of the gasbag propelling the bullet when the number of inlet nozzles is different. The calculation results show that the final shape of the expanded gasbag is pillow shaped, and wrinkles appear at the ends of the long side and in the middle of the short side of the gasbag. The stress at the wrinkles is relatively large, and the stress on the wall of the gasbag with three inlet nozzles is greater than that on the wall of the gasbag with two inlet nozzles. Affected by the changes of flow field in the gasbag and the deformation of the gasbag, the process of the gasbag propelling the bullet is divided into two stages, and there are also two large fluctuation peaks during the change of the acceleration of the bullet. Moreover, the expansion process of gasbag with two inlet nozzles lags behind that of the gasbag with three inlet nozzles, and the maximum acceleration and separation velocity of the bullet are also relatively reduced by 2% and 3%, respectively.
摘要为满足机载点药机对大质量子弹的分散需求,设计并构建了多入口喷嘴大尺寸气囊分散系统。通过内弹道过程的实验研究,验证了该分散系统的合理性和可行性。在此基础上,采用流固耦合方法对不同进口喷嘴数量下气囊推进子弹的过程进行了仿真分析。计算结果表明,膨胀后的气囊最终形状为枕形,在气囊长边两端和短边中间出现褶皱。皱褶处的应力比较大,具有三个进口喷嘴的气囊壁上的应力大于具有两个进口喷嘴的气囊壁上的应力。受气囊内流场变化和气囊变形的影响,气囊推进子弹的过程分为两个阶段,在子弹加速度变化过程中也存在两个较大的波动峰。此外,两个进口喷嘴的气囊膨胀过程滞后于三个进口喷嘴的气囊,子弹的最大加速度和分离速度也相对降低了2%和3%。
