Frontier Aerospace, founded in 1997 by rocket propulsion veteran Jim McKinnon, has a rich history in advanced propulsion solutions. It is creating the boundaries of in-space propulsion with its innovative TALOS (Thruster for the Advancement of Low-temperature Operation in Space) engines, designed to enhance the capabilities and reduce the cost of deep space missions. The company’s core mission is to conceptualize, design, and manufacture innovative rocket propulsion systems for both in-space and launch applications, providing advanced technologies like additive manufacturing.
Capabilities
Frontier Aerospace’s expertise spans the entire propulsion development lifecycle, from initial concept to design verification testing. The company’s capabilities include modern 3D parametric CAD, as well as structural, thermal, fluid and electromagnetic analysis, which allows it to produce reliable and flight-ready designs. These capabilities serve a range of key end markets, including NASA, commercial space, human spaceflight, and missile defense, with applications from lunar landers and satellite maneuvering to space debris management.
Products
- The TALOS (Thruster for the Advancement of Low-temperature Operation in Space) is the first flight-proven cold propellant engine to use MON-25. This high-performance engine can operate within a wide temperature range of −40 to 80°F and pulses roughly three times faster than similar-sized thrusters, providing superior control over the spacecraft’s movement. The TALOS engine is specifically optimized for use with MON-25, helping to reduce the cost of spacecraft destined for deep space missions by lowering power requirements and allowing for smaller, lighter systems.
- The TALOS 10-lbf Attitude Control Thruster is used to alter a spacecraft’s flight path or altitude. It stands out as the lightest in its class, weighing less than 0.34 kg, and boasts a fast response time of under 10 milliseconds.
- The TALOS 150-lbf Axial Thruster is designed for key maneuvers such as orbit insertion, lunar descent, and proximity operations, and it can also serve as a primary propulsion thruster. Weighing in at only 2.7 lbm, it represents a significant advancement in the thrust-to-weight ratio for a bipropellant engine. It has demonstrated stable operation with repeatable performance down to 12-millisecond pulses.
- The use of MON-25 fuel in TALOS engines offers several key benefits. Unlike other mixed oxides of nitrogen propellants, MON-25 does not require conditioning at extreme temperatures, which reduces the power requirements for spacecraft operating in low-temperature environments. This, in turn, enables the use of smaller batteries and solar panels, resulting in smaller, lighter, and more affordable systems overall. Furthermore, the TALOS thruster design allows for pulse-mode operation, a crucial capability for deep space missions that is not available with other MON-25/MMH thrusters.
Frontier Aerospace is positioned as a key player in the evolving space exploration landscape. By leveraging decades of expertise in liquid rocket propulsion, the company’s innovative TALOS engine offers a technically sound and reliable solution that addresses the critical challenges of deep space missions, paving the way for a new era of more efficient and affordable space travel.
