Question of the Week: Aerospace
How Strong is the ‘Ionic Wind?’

MIT has built the first-ever plane with no moving parts. Instead of turbine blades, propellers, and fans, the aircraft relies on an “ionic wind” — a silent but strong flow of ions, produced onboard, which generates enough thrust to propel the plane over a sustained, steady flight.

Low-Light Night Vision Imaging and Video Capture

Conventional night vision goggles all use image intensification (I2) tube technology that multiplies ambient, visible, and near-infrared light several thousands of times, allowing a user to see and operate in very-low-light conditions. One shortcoming of I2 tube night vision devices is that they...

Gated Chopper Integrator (GCI)

Microvolt-level signals require gains of at least a thousand. Offsets and noise in the amplifier chain will be amplified by the same amount, which can saturate the amplifier or swamp the signal so it is not resolvable. Other methods use chopping and/or autozero techniques to lower the offset and noise. The key...
