They tried it in F1, but with the high reving engine, the power required to move the valves was enormous. The performance gain was nullified by the additional power to drive the valves. The only gain was reduce vibration.

All helicopter rotor systems have to pass through its natural frequency before it gets up to its operating speed. That’s one way to cause that much vibration.
It reminds me of the Optigrab.
Subaru’s front heating element is embedded in the glass. They been doing this for quite a long time.
Because there are a lot of FAA regulations on how things are done. The seats cushions are all velcroed on and made of non-flammable materials. In fact, everything that is “attached” to the aircraft has to be burn tested before it can be accepted for use in the aircraft.
Two planes left, then Grumman will be out of Naval Aviation. So sad.
The team directors are blaming the motorcycle.
I’ve been in races where pedestrians have wondered on to the closed course and have been hit. Guess who’s at fault, not the cyclist.
Obviously you never raced in a bike race. You are allowed to use the entire road as determined by the race organizers. People will pull out of the pack like that all the time because support vehicles aren’t supposed to move through the pack at that kind of speed.
Not according to the rule book, all vehicles have to yield to the riders.
It is not on the cyclist. UCI rules basically state that the riders have the right of way. All vehicles have to yield to the riders as to not assist or impede their progress.
Cost - plus = project creep. AF will define what they want now, Northrup builds what the AF wants, AF then wants more capabilities, Northrup adds capabilities in, AF wants more, Northrup adds more, Senate asks Northrup how much it going to cost and freaks out that it is now 10x the cost and blames Northrup for being…
NTSB prelim report:
Actually I’m a flight test engineer. In fact we’re testing a Bell 407 this coming week, a longer version of the crashed helicopter.
Not speculation. I work in the helicopter industry. It’ll be at least a year before the official report comes out. Don’t believe me, go pull some final reports off the NTSB’s site.
What’s shocking is the McLaren F1 built 20+ years ago is still lighter by over 100 lbs.
By the time FAA & NTSB is done with the investigation, it’ll be at least 1 year w/no fatalities, 2 years w/fatalities, no one will remember the incident.
All the stuff I’ve been involved in required producing the material certification documents to prove what materials you used. Can’t do that with stuff you get from the local hardware store.
...and flip the cart over and end up lying in the middle of the parking lot with milk spilling all over the place.
