Purpose

This paper aims to assess the impact of electrifying the environmental control system (ECS) and ice protection system (IPS), the primary pneumatic system consumers in a conventional commercial transport aircraft, on aircraft weight, range, and fuel consumption.

Design/methodology/approach

The case study was carried out on Airbus A321-200 aircraft. Design, modelling and analysis processes were carried out on Pacelab SysArc software. Conventional and electrical ECS and IPS architectures were modelled and analysed considering different temperature profiles.

Findings

The simulation results have shown that the aircraft model with ±270 VDC ECS and IPS architecture is lighter, has a more extended range and has less relative fuel consumption. In addition, the simulation results showed that the maximum range and relative fuel economy of all three aircraft models increased slightly as the temperature increased.

Practical implications

Considering the findings in this paper, it is seen that the electrification of the conventional pneumatic system in aircraft has positive contributions in terms of weight, power consumption and fuel consumption.

Social implications

The positive contributions in terms of weight, power consumption and fuel consumption in aircraft will be direct environmental and economic contributions.

Originality/value

Apart from the conventional ECS and IPS of the aircraft, two electrical architectures, 230 VAC and ±270 VDC, were modelled and analysed. To see the effects of the three models created in different temperature profiles, analyses were done for cold day, ISA standard day and hot day temperature profiles.

商用运输机电气环境控制和防冰系统的性能分析

目的

本文旨在评估传统商用运输飞机的主要气动系统消耗者环境控制系统 (ECS) 和防冰系统 (IPS) 电气化对飞机重量、航程和燃油消耗的影响。

设计/方法论/途径

该案例研究是在空中客车 A321-200 飞机上进行的。设计、建模和分析过程在 Pacelab SysArc 软件上进行。考虑到不同的温度分布，对传统和电气 ECS 和 IPS 架构进行了建模和分析。

发现

仿真结果表明，采用±270 VDC ECS和IPS架构的飞机模型重量更轻，航程更远，相对油耗更低。此外，仿真结果表明，随着温度的升高，所有三种飞机模型的最大航程和相对燃油经济性均略有增加。

实际影响

考虑到本文的研究结果，可以看出飞机中传统气动系统的电气化在重量、功耗和燃油消耗方面具有积极的贡献。

社会影响

飞机在重量、功耗和燃油消耗方面的积极贡献将是直接的环境和经济贡献。

原创性/价值

除了飞机的传统 ECS 和 IPS 之外，还对 230 VAC 和 ±270 VDC 两种电气架构进行了建模和分析。为了了解在不同温度曲线下创建的三个模型的效果，对冷天、ISA 标准天和炎热天温度曲线进行了分析。
