Taurus Electro G2 was the first electric 2-seat aeroplane in serial production available on the market. It offers complete freedom and independence thanks to the retractable electric engine, double retractable main landing gear, excellent gliding performance, inexpensive maintenance and a well ventilated spacious cockpit.
Taurus Electro G2是全球第一款并列式双座电动滑翔机！具备收放式发动机、双主轮伸缩式起落架、优良的滑翔性能、低廉的维护费用和通风良好的宽敞驾驶舱。
Furthermore, Pipistrel believes it is the only truly useful electric aircraft out there, because the electric drive is applied to the glider airframe, where battery capacity is not a limiting factor in performance/endurance. Taurus Electro G2 represents a leap forward in performance, safety, functionality and user friendliness.
此外，Pipistrel认为Taurus Electro是目前唯一真正得到应用的电动飞机，电机系统和滑翔机完美结合，并且电池容量已不再是性能和续航能力的限制因素。Taurus Electro G2的出现代表了安全性、功能性、交互性和性能的巨大飞跃
Do you wish to fly for
absolutely free? It is possible! 真的可以自由飞翔吗？ 完全可以
Pipistrel is presenting another World’s first – the concept of Flying For Free. Pipistrel developed the Solar Trailer(R), which can charge-up the Taurus Electro G2 absolutely free and with zero emissions! Charging with the help of the Solar Trailer offers 1 kW of usable energy, this means charging time 10 hours for 30-Ah batteries and 12 hours for 40-Ah batteries.
Pipistrel正在提出世界上第一个自由飞翔概念。Pipistrel开发研制了Solar Trailer(R)，它可以为Taurus Electro G2免费充电并且实现零排放！Solar Trailer可提供1千瓦的可用功率，这意味着10小时可以充满30-Ah的电池或12小时充满的40-Ah的电池
Furthermore, when the Taurus Electro G2 is stored in the trailer during a week of bad weather, it will still be charged and ready to fly by the weekend. The Solar Trailer and Taurus Electro G2 are perfect companions and demonstrate how it is possible to fly free of charge, quietly and with absolutely zero emissions, with today’s technology!
此外，当Taurus Electro G2停在太阳能飞机储存车里，即便一周内都是阴天，它仍然可以充电，不会耽误你的周末飞行计划。Solar Trailer和Taurus Electro G2的完美结合向大家展示在当今如何利用的先进技术来实现免费的，安静的，完全零排放的完美飞行。
The trailer offers both the 12 V connection (to charge your aux. instruments, etc) and 110V/220V connections at front and back of the trailer, where you connect the Taurus Electro G2’s charger. Also present is the solar-system by-pass, so you can charge the aircraft inside the trailer when parked in the hangar/garage, for example. The buffer battery of the trailer has the capacity of 3 kWh and its energy can be transmitted directly into the Taurus Electro G2. The SolarTrailer gathers energy also when you are flying, so you charge the Taurus Electro G2 also during the night with the energy that has accumulated during the day!
Solar Trailer提供一个前置12 V输出接口（可以为AUX或其他设备供电）和两个110V/220V输入接口（前后各一个），为Taurus Electro G2提供外接电力。当飞机存放在Solar Trailer中并停放在机库里时，将Solar Trailer插上外接电源可以直接为飞机充电。Solar Trailer储蓄电池容量为3千瓦时，其电量可以直接传输到Taurus Electro G2上。
当你白天享受飞行时，停在一旁的Solar Trailer 将自行充电。晚上Solar Trailer 会将用白天储存在电池里的太阳能电量给飞机充电。
This changes everything, again 再次改变世界
Why the new generation? 为什么是新的一代？
Based on extensive testing of the Taurus Electro prototype, we decided not only to refine the product to serial production state, but rather to rethink, redesign and implement completely new solutions into the initial design. The result is what our Research and Development team calls Taurus Electro »Generation 2« or G2 in short. It is the production version and represents a great step up from the prototype。 The aircraft now has much better reliability, handling and performance.
在Taurus Electro广泛测试后，我们决定不仅要在产品上更新，而且要重新考量、重新设计和实施。最终我们的研发团队称他为Taurus Electro 2，简称G2。新版本后他在可靠性，操作性和性能上都有了巨大提升。
Can electric perform better than conventional? Absolutely!
For the first time electric power outperforms its gasoline-powered counterpart – the Taurus. Taurus Electro G2 can use a shorter runway, climbs faster and is performs much better than the gasoline-powered version when it comes to high altitude operations. All this is possible thanks to the specially-developed emission-free Pipistrel’s 40kW electric power-train.
Taurus Electro G2 比汽油发动机的性能高出太多，Taurus Electro G2使用跑道更短，爬升率更快。这一切都得益于Pipistrel’s为Taurus Electro专门研发的40kW电动机。
The tailor-developed Lithium-technology batteries come in two configurations, capable of launching the aeroplane to 1200 m (4000 ft) or 2000 m (6500 ft) respectively. They are placed in self-contained boxes, monitored constantly by the super-precise Pipistrel’s own battery management system (BMS), compete with data-logging and battery health forecasting.
The propulsion motor weighs an impressive 11 kg (rather than 16 kg) and generates 10 kW more power, resulting in a total of 40 kW. Due to this 33% increase in power and 40% decrease in weight we developed a whole new propeller, which has proven to be more efficient than the version flying on the Taurus Electro Prototype.
More than just a touch of
With the Taurus Electro G2 we are introducing a World’s first – a full set of on-board networked avionics providing for a fly-by-wire powertrain management with built-in multi-layer protection logic. Let us tell you that this represents a great improvement over the system used in the Taurus Electro prototype, where everything was handled by the pilot.
Taurus Electro G2，我们正在引进一个世界上第一个-全套机载网络航空电子设备，提供了一种内置多层保护电传动力控制系统。这是一个巨大的改进，因为在Taurus原型中的这些系统都是由飞行员人工操控的。
State-of-the-art battery system that uses information from the past to see into the future. 最先进的电池系统，利用过去的信息预测未来
The first element of this networked system is the state-of-the-art hybrid battery management system which was developed entirely in house to be able to function with tighter tolerances than commercially available systems, yielding better performance and longer battery life. The Battery Management system monitors the batteries, which were specially developed to be used in the Taurus Electro G2. They represent the absolute pinnacle of today’s battery technology, combining low weight, high power and high energy density to levels that seemed impossible as recently as 2009. The batteries are placed in alluminum boxes with dedicated power and signal connectors. Each battery cell’s performance is monitored, temperature measured and future performance predicted.
在整个飞机里最先进的就是电池管理系统，这套系统完全是内部开发而成，其兼容能力好过商业通用系统，同时也拥有更好的性能和更长的电池寿命。这款专门为Taurus Electro G2开发的电池管理系统代表了当今电池技术的绝对巅峰，将低重量、高功率和高能量密度结合，而这一切在2009年的时候是根本不可能的。电池组被存放在具有专用电源接口和信号传感器的铝箔盒中，来监控每组电池温度和状态来从而计算出其后期的使用性能。
The system is able to forecast when a battery cell is mal-performing and signals the need for a premature replacement. All parameters are also logged in the on-board flight data recorder. The four (4) battery boxes are removable and replaceable
Power controller 功率控制器
The second element is the power inverter/motor controller. It’s location has been moved into the aircraft’s fuselage, it has become more efficient and features self-protection logic against current spikes, over temperatures and other potential abnormal situations. In other words, the controller is not only driving the motor, but also providing for the low-level protection of both itself, the batteries and the motor.
Introducing the ESYS-MAN cockpit interface instrument!
The most noticeable addition to the networked system is the color-display cockpit interface instrument. The screen is really bright, in fact brighter than most displays out there, and is readable in the strongest of sunshine! It indicates the drive mode and important parameters to the pilot and provides the interface for engine retraction and extension. Everything is operated via two (2) toggle switches and a rotatable knob. The first toggle switch is the power on/off switch and does exactly that – powers up the motor controller.
The second toggle switch is the motor position selector »up/down« i.e. extended or retracted. This process is fully automated – the propeller is positioned and held in place while the motor extends or retracts. The pilot only selects the desired mode with the toggle switch. The rotary encoder acts as the throttle selector.
The beauty comes from within…ESYS-MAN is much more than just a display.
Due to the nature of electric propulsion system, we decided to employ the computational power of this cockpit interface instrument and gave it the role of the master on board computer. This means it not only displays data to the pilot, but also »talks« to every other powertrain component on board via CAN bus and makes everything sing together. It is able to detect overheating of individual components and reduce power gradually in order to maximize the climb potential with the given system status. Not only that, it provides systems diagnostics and all necessary warnings to the pilot.
ESYS-MAN was developed in cooperation with LXNAV, Pipistrel and LZ design.
Combining all elements, we have developed an aircraft which offers more performance and an almost care-free use of this revolutionary technology.
