The Future of Rotary Engines: Liquid Piston's XTS 210 Prototype

Liquid Piston, a company specializing in fuel energy conversion solutions for various Hybrid Power Systems, has been making waves in the industry with its innovative technology. The company is now exploring fuel energy conversion solutions for applications such as unmanned aerial systems (UAS), mobile power generation, and auxiliary power units (APUs). These applications require compact, lightweight, efficient, and multi-fuel capable engines that can meet demanding performance and environmental standards.

The Liquid Piston engine is designed to meet these requirements and offers up to 10 times more power density than conventional engines. The company's focus on developing scalable combustion engines has drawn the attention of the US military, particularly with regards to their interest in the XTS 210 prototype. This engine, which relies on a supercharger to deliver boost pressures equivalent to 14.5 PSI, is capable of delivering smooth power from a lightweight package roughly the size of a basketball.

The XTS 210 engine has four major market requirements that it had to address in order to be labeled as a viable power solution: portability and configurability, spark ignition (SI) or compression ignition (CI) capability, liquid cooling, and multifuel readiness. The engine is designed to operate in both engine-only and hybrid electric modes, depending on the application and power demand. It can also run up to 7,000 RPM, which is ideal for small, lightweight electrical machines such as generators, motors, and inverters.

The XTS 210 provides five times the power-to-weight specific power and three times the torque-to-weight specific torque compared to traditional diesel piston engines of similar power. This means that the engine can deliver more power with less weight and size, which is crucial for reducing fuel consumption and increasing payload capacity. The engine's design also allows it to be configured to rely on either compression or spark ignition depending on the fuel type and engine mode.

The XTS 210 is designed with military-grade robustness in mind from inception, meaning that it can withstand harsh operating conditions and extreme temperatures. It can also be configured to run on a wide range of fuels without compromising performance or reliability, making it an ideal solution for applications that require flexibility. The engine uses a coolant fluid to transfer heat from the engine to a radiator or heat exchanger, which is essential for maintaining optimal engine temperature and preventing overheating or thermal damage.

In addition to its military applications, the XTS 210 has potential in the aerospace industry, where it can be used as an auxiliary power unit (APU) for vertical takeoff and landing aircraft (VTOLs). The engine's compact size and high power-to-weight ratio make it an ideal solution for small, lightweight electric power generation systems. Liquid Piston hopes that its XTS 210 engine will revolutionize the rotary engine market and offer a viable alternative to piston engines for various applications.

The company plans to deliver an XTS 210 prototype to the US Army around 2024 while continuing to develop various rotary engine variants for military use. Liquid Piston also intends to license its technology to other manufacturers and partners who are interested in using its engines for their products. The company believes that its engines can be used for electric cars, urban aircraft, drones, vehicles, and power generation.

Liquid Piston's ambition is to establish the XTS 210 engine as the most reliable and practical power source globally. They want it to be so sturdy and user-friendly that both commercial and military applications can seamlessly integrate this engine. Furthermore, the company plans to explore mobile electric power generation by employing the XTS 210 for primary or hybrid electric propulsive power for vertical takeoff and landing aircraft (VTOLs) and small unmanned aircraft systems (UAS) in the near future.

Overall, Liquid Piston's XTS 210 prototype represents a significant breakthrough in rotary engine technology. With its compact size, high power-to-weight ratio, and multifuel readiness, it has the potential to revolutionize various industries, from aerospace to electric vehicles. As the company continues to develop and refine its technology, we can expect to see more exciting innovations from Liquid Piston in the years to come.
