Nexus贝尔飞行汽车控制系统解析

2019-03-31 23:12

贝尔Nexus飞行汽车将采用最先进的控制技术,可以实现全自动飞行,但是从设计中的飞行控制台以及飞行员座椅来看,贝尔并不急于以全自动的方式运营这款飞行汽车,而最先进的控制系统加上飞行员作为最终保护环节,其控制系统的可靠性也是不需要质疑的。

贝尔主导了Nexus的设计、研发和生产,虽然团队中没有硅谷的力量,但它的供应商合作伙伴,佳明(Garmin)、赛峰(Safran)、EPS(Electric Power Systems)、泰雷兹(Thales)、穆格(Moog)等,都拥有许多年的飞行器相关生产经验、政府认证和安全理念。其中佳明负责整合航电系统和飞行器管理计算机、赛峰提供混合动力解决方案、EPS提供能量存储系统、泰雷兹负责飞行控制计算机的硬件和软件、Moog则提供飞控作动系统。机身的供应商暂时还没有公布。

所以,贝尔绝不像一些昙花一现的初创公司,无论是基于贝尔的技术积累还是与各大供应商达成的合作关系,Nexus也不是一款头脑一热就开发的产品。不仅如此,对于自动驾驶的态度也体现了贝尔对于产品开发的谨慎性,也是与其他一些初创公司所不同的。

据贝尔表示,Nexus上的自动驾驶功能并不会太早被应用,但毫无疑问会在未来配备全自动驾驶技术,这也是为什么贝尔在Nexus客舱的前排依旧专门保留了一个驾驶员席位。他们认为无论是全自动驾驶的技术还是政策规定,都仍然需要许多年才能落地,所以驾驶员是必要的。但Nexus是具备全自动驾驶的能力的,高级的辅助控制功能会在前期先运用进来。所以驾驶一台Nexus并不需要传统飞行员那样严格的飞行驾驶训练。而基于对驾驶员的需求,贝尔也在开发产品的同时,也在研究新的飞行管理系统。 车云小结 Nexus代表了贝尔公司对于未来产品的定位,一款可以舒适乘坐四名乘客和一名驾驶员的小型、经济的飞行器,这也是贝尔公司在与时俱进的转型过程中最重要的首款产品。展台上的目前的唯一一架原型机,贝尔预计将在2020年推出这款空中出租车的首款量产机型,之后逐步交付市场,2025年之前实现大规模生产运营。不过以Nexus为首的飞行产品在未来落地之前,除了要重新规划整个空中飞行控制,同样需要面临一系列的法律法规的批准和讨论。

The Bell Nexus flying car will use the most advanced control technology to achieve fully automatic flight, but from the design of the flight console and the pilot seat, Bell is not eager to operate the flying car in a fully automatic way, and most The advanced control system plus the pilot as the final protection link, the reliability of its control system is also not questionable.

Bell dominated the design, development and production of Nexus. Although there is no Silicon Valley power in the team, its supplier partners, Garmin, Safran, EPS (Electric Power Systems), Thales (Thales) ), Moog, etc., have many years of experience in aircraft related production, government certification and safety concepts. Among them, Garmin is responsible for integrating avionics systems and aircraft management computers, Safran provides hybrid solutions, EPS provides energy storage systems, Thales is responsible for flight control computer hardware and software, and Moog provides flight control actuation systems. The supplier of the fuselage has not yet announced.

Therefore, Bell is not like some short-lived startups. Whether it is based on Bell's technology accumulation or cooperation with major suppliers, Nexus is not a product developed with great enthusiasm. Not only that, but the attitude of autonomous driving also reflects Bell's cautiousness in product development, and is different from other startups.

According to Bell, the autopilot function on the Nexus will not be applied too early, but there will no doubt be equipped with fully automated driving technology in the future, which is why Bell still retains a driver seat in the front row of the Nexus cabin. They believe that whether it is fully automatic driving technology or policy regulations, it still takes many years to land, so the driver is necessary. However, the Nexus is fully capable of driving, and advanced auxiliary control functions will be used in the early stage. So driving a Nexus does not require the rigorous flight driving training of a traditional pilot. Based on the demand for drivers, Bell is also developing new flight management systems while developing products. The car cloud summary Nexus represents Bell's positioning for future products, a small, economical aircraft that can comfortably ride four passengers and one driver, which is the most important for Bell's transformation in the process of advancing with the times. The first product. At the current stand-alone prototype on the stand, Bell is expected to launch the first production model of this air taxi in 2020, and then gradually deliver it to the market and achieve mass production operations by 2025. However, before the landing of Nexus-based flight products, in addition to re-planning the entire air flight control, it is also necessary to face a series of laws and regulations approval and discussion.
