It's rather like maple tree seeds. The falling action causes them to spin and the spinning action slows them down. An autogyro's blades are designed in such as way that the rotor generates enough lift to work against its weight with proper forward acceleration. You might liken an autogyro more as a wingless plane than a helicopter.
Though helicopters can use the same principle in unpowered emergencies to land softly instead of dropping like a stone.
Note how the autogyro's top blades are canted backwards; if you rotated the image at the top of that page so the airflow was coming directly from the left, the helicopter's rotors would be canted the same way. So, slap an engine on the front to pull it along that way, and presto.
The Kayaba Ka-1 autogyro had an empty weight of 775kg. She's ambitious to field something with an empty weight of about 6000kg.
A bigger problem is that that from what I can tell she has a wooden deck and the direct vectored thrust coming out of a harrier's engine will warp a solid steel one without special deigns consideration. A single harrier might get off the deck once... but it would presumably do so at the head of a pillar of flame as it immolated the flight deck along the way. Which would, admittedly, probably look pretty metal.
The F-35 is even worse, somehow it seems that no one paused to consider what the fact it's engine was way more powerful then the harrier would mean in terms of structural heating of what it was sitting on. Turns out that the effect was that the asphalt became liquid, concentrate abated into flakes, and steel flight decks got so hot there was a risk of structural weakening when the nozzle is pointed down too long or multiple aircraft used a single area... opps.
Though it is sort of awesome in a twisted way to say that you've created a flying machine that can incinerate rocks and melt metal with a mere byproduct of it's operation. Another fun fact along that vein is that the drive shaft off the turbine to the lift fan on the 35B can be fairly accurately measured in horsepower since it's mechanical energy. When fully engaged it's about 30,000 horsepower, approaching 75% of the output of most World War II destroyers.
Somebody should stop her before she watches one of the absolute worst Arnold movies ever.
