Portal Aircraft Company

Portal Aircraft Company (PAC) is a Texas-based aerospace startup developing next-generation gas turbine–powered VTOL aircraft for defense and commercial markets. PAC’s patented distributed turbine architecture replaces complex helicopter drivetrains and battery-dependent eVTOL systems with a simplified, fuel-powered design optimized for long endurance, rugged field sustainment, and contested environments. PAC aircraft are designed for missions including contested logistics, long-range ISR, launched effects support, and austere operations where battery-electric systems fail due to range, recharge constraints, and infrastructure dependence. The company has been validated by winning Army xTechSearch 9 (24 winners selected from 840+ applicants), achieving DARPA ERIS “Awardable” status, securing a Phase I SBIR contract, and forming a partnership with Texas A&M University for engineering and manufacturing support. PAC is building scalable turbine-powered VTOL platforms designed to deliver long endurance, field repairability, and mission flexibility at venture scale.
