Scope changeAs per our previous briefings, unfortunately, we have had to revise the scope of this project due to our supplier of airframes no longer being in a position to do so in the time remaining for this project. We have little confidence that we will ever receive the Pegasus subscale air vehicles and therefore proposing to complete various elements of the work considering different target platforms. We have made every effort to support our supplier over the last 24 months, however we are now at the stage where we need to make a change to allow us to move forward and realise the benefits from this project. In the paragraphs below we have indicated the status of the existing work packages and, in particular, have identified those work packages which we are no longer in a position to complete. Additionally, we have proposed updated work packages where we believe that useful and relevant work can be completed within the overall scope and objectives of the original programme. For some of the revised work packages we are proposing a medium-sized cargo drone configured for conventional landing and take-off as an example of a likely near-term growth area. For the other revised work packages we are proposing an existing Callen-Lenz Koios air vehicle as an example of something capable of vertical take-off and landing.

根据我们之前的简报，不幸的是，我们不得不修改这个项目的范围，因为我们的机身供应商在这个项目剩下的时间里不再有能力这样做。我们不太相信我们会收到飞马的次规模飞行器，因此建议完成考虑不同目标平台的各种工作要素。在过去的24个月里，我们尽了一切努力来支持我们的供应商，但是我们现在处于需要做出改变的阶段，以使我们能够向前发展，并从这个项目中获益。在下面的各段中，我们指出了现有工作包的状况，特别是指出了我们不再能够完成的那些工作包。此外，我们还提出了更新的一揽子工作方案，我们认为可以在原方案的总体范围和目标内完成有用和相关的工作。对于一些修订后的工作包，我们建议将中型货运无人机配置为常规起降，作为近期可能增长领域的一个例子。对于其他修订后的工作包，我们建议使用现有的卡伦-伦茨Koios飞行器作为能够垂直起降的例子。工作包0：管理、治理和利益相关者参与工作包目标时间、成本和质量管理。在已定义的流程和策略内进行治理。内部和外部项目报告。工作描述与原范围无变化。工作包1.1：认证路径wp1.1 a认证方法-完成PUA全尺寸实验vj . wp1.1 a认证方法-额外工作•为中型货运无人机提出高级假设。•审查CAA/EASA对该车型可能施加的要求。•与监管机构合作，审查基线方法。wp1.1 b认证要求-完成PUA全面实验VBJWP1.1b认证要求-额外工作•根据WP1.1a中商定的方法制定认证要求•确定将用于建立FCSWP1.1c FCS认证计划认证基础的要求-完成PUA全面实验VBJ.WP1.1c FCS认证计划-额外工作•使用基于模型的开发方法为拟议的中型货运无人机起草认证计划。•认证计划应记录wp11 . b的要求，形成预期的认证基础，并包括预期的符合性手段。工作包1.2：控制系统开发WP1.2a系统设计-为VBJWP1.2a系统设计完成-附加工作•根据现有设计和安全文档，对中型货运无人机的拟议假设进行初始全机审查•生成用于原型设计阶段的系统设计描述（SDD）。•为建议的设计提供功能危害评估（FHA）和初步系统安全评估（PSSA）。•对FCSWP1.2b控制系统要求进行概念设计评审，完成VBJ配置，无需额外工作。WP1.2c建模和仿真-完成VBJ配置。WP1.2c建模和仿真-额外工作建议使用现有的Callen-Lenz Koios飞行器，能够垂直起降。•将已经为VBJ生产的飞机飞行物理模型（6-DOF）用于Koios配置。•设计和建造测试平台，以验证推进和驱动系统。•进行钻机试验，收集所需数据。•为Koios开发工具采购和安装额外的仪器。•在Koios开发飞行器上进行特定的飞行试验，以收集飞行数据。•使用获得的数据来验证Koios飞行物理模型。•同意用户对次级飞机FCS和GCS的新软件产品的需求-完成VBJ配置•使用Simulink自动代码生成设计和开发软件，必要时辅以手工编码-完成VBJ配置•执行软件测试包括基于飞机飞行模型的硬件在环仿真和建模活动-完成VBJ配置•执行航空电子集成活动，以确保所有接口和系统功能可用，在子尺度平台集成和地面故障查找之前-由于VBJ子尺度飞机不可用而未执行额外的工作，以产生中型货运无人机的硬件在环测试能力。•将FDM配置为货机•开发自动化测试框架•配置可视化包工作包2：通信，导航和监视系统所有交付成果完成并交付。WP2不包括在本项目变更请求中。工作包3：小尺度开发和准备由于无法获得PUA小尺度飞机，该工作包仅部分完成。建议进行更多的工作，以便收集必要的数据，以验证在WP1.2c项下拟议的额外工作中确定的Koios飞行物理模型。额外工作的细节如下：wp3.1次尺度原型机的后勤和接收-没有进一步的工作建议；dwp3.2次尺度飞机设计和集成-没有关于VBJ平台的进一步工作建议；WP3.2飞机设计和集成-额外的工作•为Koios开发车辆开发附加仪器开发安装设计•为Koios开发车辆提供改装套件•设计和制造推进装置wp3.3系统安装-不建议对VBJ平台进行进一步的工作wp3.3系统安装-额外的工作•在Koios开发车辆上安装额外的仪器wp3.4地面测试-不建议对VBJ平台进行进一步的工作wp3.4地面测试-额外的工作•在Koios开发车辆上安装额外的仪器•进行推进和驱动测试的测试和数据收集rigsWP3.5捕获一般学习-没有进一步的工作建议工作包4：飞行试验swp4.1飞行程序开发-没有关于VBJ平台的进一步工作建议wp4.1飞行程序开发-额外工作•为Koios车辆制定飞行测试文档和测试程序•生成操作安全案例并确认适当的飞行授权swp4.2试验基础设施准备-没有关于VBJ平台的进一步工作建议wp4.2试验基础设施准备-额外工作•检查和附加仪器的功能测试wp4.3测试准备-没有关于VBJWP4.3测试准备的进一步工作-额外的工作•对Koios飞机进行测试准备审查twp4.4飞行测试计划-没有关于VBJWP4.4飞行测试计划的进一步工作-额外的工作•进行飞机飞行测试（VLOS）收集所需的数据Koios模型验证按照WP4.1 WP4.5分析和定义的程序报告-没有关于VBJWP4.5分析和报告的进一步工作建议-额外的工作•分析Koios FDM验证所需的数据。wp4.6捕获通用学习-没有进一步的工作建议。
