Getting LEO Spacecraft Assembly Lines Up to Speed with Infrared

If you’re building commercial spacecraft for Low Earth Orbit, you know the drill. The old way of doing things—bespoke, slow-cycle heating—just doesn’t cut it anymore. Waiting for a massive convection oven to heat up is a nightmare. You’re basically wasting a ton of energy just to warm up the air in a giant room. We’ve found a better way. We use short-wave infrared (SWIR) arrays. Instead of soaking the entire airframe in heat, we just hit the specific composite bonds and adhesive zones that actually need the cure. It’s precise. It’s fast. And it saves a lot of headaches. The nitty-gritty on power and density When we’re spec-ing out these lamps, it’s all about how the material absorbs heat. We use high-wattage quartz lamps because they push radiant energy deep into carbon-fiber reinforced polymers (CFRP). But here’s a tip: watch your voltage. Whether your plant runs on 220V or 380V, you have to match it perfectly. If you don’t, you’ll deal with massive voltage drops across those long assembly lines, and nothing will cure properly. The best part? High-density arrays take up way less space. That gives you more breathing room on the floor for your robotic arms and sensors. Why quartz? We stick with halogen-filled quartz tubes. They stay stable even when you’re pushing them hard. Sometimes we use coated tubes to shift the spectrum—this is a lifesaver because it keeps the surface from scorching while the core of the part actually reaches the temperature it needs. We also use standard connectors, like R7s or SK15. Why? Because things break. When a lamp burns out in the middle of a cycle, your technician can just pop a new one in and get moving again. No one wants to spend three hours rewiring a whole rack just to replace one bulb. The trade-offs (because nothing is perfect) Look, IR heating is incredibly fast, but you can’t just “set it and forget it.” Radiant heat moves in a straight line. If your part has weird angles or deep pockets, you’re going to get cold spots. To fix that, you’ve got to pair the array with closed-loop pyrometers that adjust the power on the fly. And one last thing: these arrays put out a lot of heat. A lot. If your HVAC isn’t beefy enough to handle the waste, your operators are going to feel like they’re working in a sauna. Make sure your cooling is sorted before you flip the switch.
