Coming Soon - Flexible Coupling Solutions for OEM Applications

Gain insights into specifying a flexible coupling for your application that offers the best combination of value and performance. Attendees will see examples of solutions provided for real world applications that leveraged the engineering support and technical skill of Helical Products. Designing and manufacturing a custom coupling for OEM applications provides savings by optimizing the size and targeting environmental conditions that would not be met by off-the-shelf products. The incorporation of special attachment features will reduce the time and expense of design, purchase and inventory of multiple parts.

Tool Designs for Friction Stir Welding

This repeatable, environmentally friendly, cost-effective weld method is able to weld traditionally “unweldable” alloys.Friction stir welding (FSW) is a solidstate welding process that shows promise in the aerospace industry. A new system of experimentation has been used to quickly make and screen new tool designs. After conducting a literature review, friction stir tools were designed to optimize material flow around the tool.

Techniques for Conducting Effective Concept Design and Design-to-Cost Trade Studies

Concept design plays a central role in project success for space missions, as the product of concept design effectively locks in the majority of system lifecycle cost. It involves a concurrent investigation of requirements and multiple mission characteristics such as flight dynamics, design, performance, concept of operations, technology, verification approach, launch and ground interfaces, cost, schedule, and risk.

High-Performance Fault-Tolerant xEmbedded Computing (HPFEC) Benchmark Suite

This work arises out of the Next Generation Space Processor (NGSP) project, a collaborative effort among several NASA centers and the Air Force Research Laboratory. The goal of NGSP is to develop the next generation of radiation-hardened, fault-tolerant, space-worthy computing systems consisting of hardware and system software. To drive and evaluate the design, each of the NGSP collaborators contributed benchmarks. This article describes the benchmarks developed at the Jet Propulsion Laboratory (JPL). Collectively, these benchmarks are called the HighPerformance Fault-Tolerant Embedded Computing (HPFEC) benchmark suite.

Coming Soon - Polarimetric Radar for Autonomous Drive

In Conjunction with SAEThe automotive industry is moving rapidly from driver assistance applications to safety-critical perception systems that independently make decisions. These perception systems need to be able to reliably detect the orientation and the type of target in any environmental condition. This 30-minute Webinar examines a new polarimetric radar sensor for autonomous and highly automated drive applications. Experts discuss how this technology will dramatically improve the performance and reliability of automotive sensor suites in all environmental conditions.
