 | 60 years ago: First flight of NASA's Lunar Landing Research Vehicle
Neil Armstrong called it unconventional, contrary, and ugly, but the Lunar Landing Research Vehicle provided "a substantial contribution to the Apollo program." Built before NASA had selected the strategy that would use the Lunar Module, the LLRV used a downward-pointing turbofan engine, two rockets for descent and horizontal translation, and 16 thrusters for three-axis attitude control. It was the first pure fly-by-wire aircraft to fly in Earth's atmosphere. By John Uri, NASA's Johnson Space Center

 | Tech Tip: Smalley Wave Springs for tight applications
Smalley's Wave Springs are engineered for tight spaces! These flat-wire compression springs are designed to optimize space within assemblies, making them a popular choice across all industries. Compared to traditional round wire coil springs, Wave Springs can reduce axial space by up to 50% while delivering the same spring force and deflection. They're available in diameters as small as 3 mm and in a variety of materials, including stainless steel, to meet diverse application needs.

 | How Nord-Lock washers work: Get an edge with a wedge
Can you get a design and functional edge with a wedge? In this animated video, Nord-Lock explains the principle behind their original wedge-locking technology, which secures bolted joints even when exposed to severe vibration and dynamic loads. The company says it is impossible for this washer type to loosen unintentionally, due to the wedge created underneath the bolt head and nut.

 | New polymer bearings are PFAS- and PTFE-free
igus has developed a new polymer bearing material called iglide JPF that is free of both per- and polyfluoroalkyl substances (PFAS) and polytetrafluoroethylene (PTFE). This innovation marks an important step in the company's efforts to create sustainable alternatives to conventional plain bearings. JPF is a dry-running, wear-resistant polymer that offers comparable friction and wear performance to iglide J. It delivers high wear resistance and durability.

| | Videos+: Technologies and inspiration in action | Maximize space and cut costs with Smalley Wave Springs
Smalley Wave Springs offer a unique solution for space savings, replacing traditional coil springs to reduce spring height and cavity size. This compact design lowers material costs and assembly size. Acting as load-bearing devices, wave springs compensate for dimensional variations within assemblies, providing a precise spring rate where load is proportional to deflection. Achieve reliable, cost-effective performance with Smalley's advanced Wave Spring technology.
