Engineering Services

Through our base of partners and a broad network of high-level engineering talent, we can provide an array of engineering support and special analysis services. These vary from short-term, quick-turnaround projects to much longer term, more detailed engineering studies.

Direct Leap Space Division is pleased to offer design and analysis services in areas listed below. Most of the services are applicable to many types of aerospace vehicles, including aircraft, expendable and reusable launch vehicles, spacecraft, aerobraking or atmospheric entry capsules, and satellites.

Aerospace Mission Design

Mission Planning, and Trajectory Simulation/Analysis. Analysis with varying complexity, ranging from top level issues (such as propellant usage and launch vehicle selection) to detailed analysis (including Three and Six Degree of Freedom (3 DOF and 6 DOF) trajectory/orbit design, optimization, and simulation). Tools include NASA's Program to Optimize Simulated Trajectories (POST), Analytical Graphics' Satellite Tool Kit (STK), and in-house developed simulation programs.

Communications Analysis and Services. Analysis and design of ground-spacecraft communication links. We can also arrange for terrestrial communications stations and mission-control facilities.

Control Systems Design and Analysis. Design, modeling, and analysis of guidance and control systems for all types of aerospace vehicles. Tools include Mathworks' MATLAB and Simulink, and in-house developed codes.

Aerodynamic Analysis

Aerothermal and Thermostructural Analysis. Analysis of the aerodynamic heating a vehicle will encounter, and how well a given Thermal Protection System (TPS) protects a vehicle from this heat. Tools include NASA's MINIVER analysis code.

Broad Spectrum Aerodynamic Analysis. Determination of aerodynamic forces and moments from low speed, subsonic airflows through supersonic (Mach 1-5) and hypersonic (Mach 5 or greater) flows. Tools include NASA's Aerodynamic Preliminary Analysis System (APAS).

Aerospace Computer Systems

Software Design, Modification, and Implementation. Done in languages including Fortran, C, and Java using PC, MAC and UNIX operating systems. Our personnel have extensive experience in simulation, modeling, and analysis software for scientific and engineering applications. Specific areas include system simulation; image processing and analysis; and data reduction, analysis, and presentation.

Embedded Systems. We can develop embedded computer systems for almost any application or environment. Possible applications include data collection, command & control, and navigation. Features can include digital and analog input/output, image acquisition and processing, Global Positioning System acquisition, environmental sensors such as temperature and pressure, and embedded Internet and Web service.

Build and Test

Mass Properties Determination. Total vehicle mass, center of gravity, and mass moments of inertia.

Test Systems. We have specific expertise in the development of systems for providing stimulation signals to devices under test and collecting, analyzing, and storing the results. Systems to be tested can include electronic, electromechanical, mechanical, and optical elements. Stimulation can be purely electrical, or can include mechanical and optical inputs. In addition, vibration and thermal environments can be simulated.
