First-Stage Tanks for Kistler K-1 Launch Vehicle

The Kistler K-1 was a reusable launch vehicle consisting of two stages: a Launch Assist Platform (LAP) and an Orbital Vehicle (OV), both using liquid oxygen (LOX)/rocket propellant (RP) engines. ATA took responsibility for the design and analysis of the LAP LOX tank before it became a schedule-critical item.

Flight and Landing Analysis of the Pad Abort Demonstrator

The Lockheed Martin launch Pad Abort Demonstrator (PAD) was used as a test bed to demonstrate crew escape technologies and validate analytical models for future crew escape systems. The PAD test bed was designed to use fully instrumented mannequins to provide data on crew environments during test and checkout of crew escape propulsion systems, parachute […]

Ground Vibration Test and Structural Mode Interaction Assessment of an Aircraft

Tamarack Aerospace Group (Tamarack) does airplane modifications. In this project, Tamarack retrofitted specialized winglets, with active camber surfaces, to an existing airplane. That modification requires EASA and FAA certification of the aircraft.

Hangar Wake Impact Study

ATA used steady and time-accurate computational fluid dynamics (CFD) simulations to quantify the impact of a newly proposed helicopter hangar’s wake on the operation of landing aircraft on a nearby runway at a regional airport. The analysis showed that the larger hangar structure and closer dimensionless spacing from the runway would exacerbate wake effects relative […]

Hospital Campus Wind Mitigation CFD Analysis Study Case Study

ATA used computational fluid dynamics (CFD) simulations to analyze the high-velocity winds and several mitigating structure designs at the Yuma Regional Medical Center (YRMC), with the goal of reducing airflow velocities experienced in an outdoor dining area. ATA collaborated with the architecture firm ARCHSOL to reach a design that reduced dining area winds below the […]

Human Landing System Engineering Support

Dynetics, a wholly owned subsidiary of Leidos, was selected by NASA to design the Human Landing System (HLS), which will allow the first woman and the next man to land on the Moon under the Artemis Program. ATA is part of the team assembled to develop the Dynetics HLS (DHLS) and is performing a variety […]

Hyper-X Flutter Analysis

NASA’s experimental scramjet flight vehicle, the X-43, defies the current standard of jet engines. Instead of carrying the oxygen required for combustion, the supersonic combustion ramjet, or scramjet, has the potential to revolutionize space travel as the first implementation of an air-breathing ramjet engine.

Infrared Sensor Package Prototype

A defense prime contractor awarded ATA Engineering a contract to design the packaging for an infrared sensor to be used on an unmanned aerial vehicle. During preliminary analysis, it was determined that the aerodynamic pressure on a fixed sensor window during flight would require a very costly, high-strength material that would have an unacceptably adverse […]
