So I love the old StarGate series and one of the icons of the series was the use of the FN P90 bull pup machine pistol with its 50 round transparent plastic magazine on the top of the barrel, just popping off the bad Egyptian dudes by the dozens.
The reality was that this French sponsored weapon was not just a prop. Developed in the 80’s as better than a pistol, sub machine gun or rifle for vehicle crews and security forces . Something with the ability to penetrate bullet proof vests, carry a lot of rounds, but not load the soldier down or make a big visual impression.
The core of this is the 5.7×28 mm round…a center fire 22 pistol round. With the ability to accurately hit and penetrate at moderate range. A 9in (ish) barrel in a bull pup kept the weapon short. The plastic magazine was bizarre but worked, stacking the rounds sideways with a ramp/pivot to feed the rounds into the chamber. It doesn’t sound like a great idea but apparently it was engineered well and does the job reliably while providing 50 rounds.
The 5.7×28 round has started to make an impact with the current interest in self defense and concealed carry. The Ruger 57, the FN 57 pistol both are modest successes and deservedly so. Now KelTec kicked it up a whole lot with this 5.7x28mm Maxi Pistol…really a bit of a competitor to the P90 which may be out of print now. It is a wild take on what is supposed to be a personal ‘side arm’ but it certainly makes an impression.
Arens’ automotive-hardened traction inverters with power ranges from 30 to 500 kW (40 to 670 hp) are for applications ranging from large transit buses and medium-duty trucks to hybrid passenger cars. With the Powerpac series, adapting an existing vehicle design to hybrid power does not involve intensive re-engineering. The Arens Powerpac 100-kW (134-hp) traction inverter features a high power density in a compact enclosure designed to fit with the battery, in the vehicle’s existing battery box. The inverter offers an insulated gate bipolar transistor-based design and is suitable for truck, bus, agricultural, and construction equipment applications. All Arens inverters feature cast enclosures sealed to IP67 with intelligent thermal protection.
Very much like what my team at SatCom came up with for the AIPM Advanced (or Automotive depending on the audience) Integrated Power Module. The switches are bolted to the base the bus bar connects across them with capacitors integrated as close to the devices as possible and the gate drive and controller board on the other major flat face. Doubt any of the Aren’s team ever saw anything we did, it’s just the most economic and sensible use of surfaces and volumes to get the best performance.
