    Apparently this hairdryer removes any and all water from hair at mach 1.2
    This technology will allow wives to leave the house nearly two minutes faster than when using a standard hairdryer. While capable of gaining nearly seven minutes of "ready" time testing showed several hours of training was required for the intended consumer due to 1. Product is scary 2. No choice of color 3. Nobody explained that 4. Husband is a complete asshole 5. It's probably a vibrator, I'm going to my mom's...
    At PBS War Machines we listen to our buyers and we're proud to announce the HairJet will be available in pink as well as standard military grey.

    Why is it using a radial compressor wheel and an axial exhaust turbine? What is this for?

      It's a small form factor jet engine designed for mainly military purposes like UAVs, target drones and maybe even cruise missiles. These types of engines usually employ a centrifugal compressor for the high-pressure stage. Turbines are always axial impulse-reaction in jet engines.

    Hi
    What are the tiny holes in the compressor?

    • @Bialy_1

      Looks like its for weight reduction.
      Planes are full of this type of holes as the metal on the edge is doing most of the work, stuff inside is only to hold the edge part in proper place and not alow it to deform, large round holes reduce the risk of tearing in the metal -> the hole does not create a stress concentration area -> that is why windows in planes have rounded corners.
      Here it is probably also for allowing some air flow on the outside as the engine is not moving so extra circulation via this holes may be needed.
