The team
behind GTL

Two decades of working the hardest aerospace problems — cryogenic composite structures, combustion instability, and rocket engine development — under a leadership team that has delivered it firsthand.

Paul Gloyer

Paul Gloyer

President

An experienced executive and accomplished program manager with 25 years delivering technical solutions to the aerospace industry's hardest problems. He has led development of a wide range of aerospace systems — the PA-X suborbital rocket, the PA-E15k rocket engine, the SPORT orbit-transfer vehicle, and the Encounter solar-sail craft — spanning small integrated systems to large, complex space-mission architectures.

Zachary Taylor

Zachary Taylor

VP, ENGINEERING

Extensive experience designing, fabricating, and testing a broad range of composite structures — pressure vessels for rockets, satellites, and commercial use, plus rocket structures, wings, and fins. His design skills are backed by years of practical shop experience across composites, metals, polymers, and ceramics, and he has directed teams through every stage from design and analysis to fabrication and commercial production.

Dr. Gary Flandro

Dr. Gary Flandro

Chief Engineer

One of the world's leading experts in combustion instability, fluid dynamics, and aerospace systems. Early in his career he discovered the Grand Tour opportunity that enabled the first and second Voyager explorations. Over 40 years he has focused on combustion instability, and his breakthroughs form the basis of the UCDS Model — an unprecedented capability to accurately predict the stability of steady-flow combustion devices.

Dr. Eric Jacob

Dr. Eric Jacob

Director of Programs

An aerospace-systems design and development expert with 20 years of experience and a seasoned principal investigator. His work spans cryogenic systems, aircraft and space-vehicle design, rocket-engine design and testing, and UAS development and flight. Dr. Jacob has invented novel methods for optimizing rocket launch vehicles and trajectories, as well as innovative liquid rocket engines and rotating detonation engines.

Dr. Joshua Batterson

Dr. Joshua Batterson

DIRECTOR OF ENGINEERING
DIRECTOR of Modeling and Simulation

Leads GTL's Modeling & Simulation department, developing numerical algorithms spanning acoustic, vorticity, thermal, and hydrodynamic wave solvers, genetic algorithms, smoothed-particle hydrodynamics, and structural mechanics. His work established GTL's custom multi-physics framework — a compressible reacting-flow CFD algorithm, conjugate heat transfer, acoustics, and structural mechanics. He also operates GTL's in-house hydrogen liquefaction system, producing up to 149 L of liquid hydrogen for cryogenic tests, and led the effort to test GTL's composite tanks with liquid helium — repeatedly achieving a super-fluid state.
