Berliner Helicopter

This is another picture of the Berliner helicopter. It is hard for me to figure out how this thing flies. There are two large upward pointing rotors in front, and it looks like a small one back near the tail.

  1. This is a weird aircraft. You're correct that it has a third propeller near the tail. Here's a description of how this flies:

    In 1922, Henry ordered a surplus Nieuport 23 fighter fuselage and mounted a Bentley 220 hp engine to the front. He attached a spar
    mid-way up the fuselage to form the bottom of a truss extending from the sides of the aircraft. The trusses each supported one of the two counter-rotating lifting rotors, which the engine powered through a series of geared shafts. The two rotors could tilt slightly in opposite directions to control yaw.

    A variable-pitch tail rotor, 76 cm (30 in) in diameter, mounted horizontally in front of the vertical stabilizer, maintained pitch control while hovering. To initiate forward flight, the pilot pushed forward on the stick to increase the pitch of the horizontal tail rotor, which dropped the nose and inclined the lifting propellers slightly to initiate forward flight.

  2. OK, PJM, I will add a comment. We certainly don't want an embargo! The lumberjacks were great. Not as thrilled with the helicopters. How about a handsome & daring young pilot in one of those tight leather helmet-hats?

  3. Love the section on helicoptors! It would take a braver man than me to fly in one of them, though!!

  4. Last year when you were blogging on the Toenail Trail Parade, you mentioned that you were considering an ultralight. Is this still in the works or have you moved on to helicopters? Personally, I think your bison would be easier to herd with aircraft than a tractor.

  5. Skip the helicopters. Let's get back to pictures of well-built handsome young men, errr, ahhh, workers.

  6. It looks like the ladies are only interested in us if we model for them. Please don't denegrate us by ignoring the more important things in life like helicopters, airplanes and tractors

  7. So I guess it get it's forward drive like the Osprey. The propellers tip forward to give it movement. The Osprey tilts it wings for forward momentum.

  8. Us guys like things with motors on them.
    The bigger the motor the better.

    Yeah, put a photo of the Osprey in there, so people can see what you are talking about. Or are you just doing old, old stuff.

  9. Threatening embargo to get comments, what a shameful tactic. At least you're not getting any hateful comments (that I can see anyway) this time.

    I don't normally comment, but really enjoy your pictures and the domestic updates. Don't stop now.

    I enjoy the variety of subjects you post. Don't give up now.

  11. I agree with Anna Cotton, a shameful tactic, but it appears to be working.

  12. So what is your target comment total for a day, or is it total for a week?

  14. I am fascinated by all the comments, not so much by the oddball aircraft.

  16. I have been enjoying helicopter week at OPotD, but I'm still waiting for the pictures of the multi-colored eggs the chickies lay. Maybe in the next Sunday update?

  17. I realize you are making your threat with your tongue firmly planted in your cheek. However, I caution you to greatful for the number of page visits you get and not the number of comments. I'm delighted with one or two comments to 30 or 40 visits. Moral of my story is to be careful what you wish for, self fulfilling prophecy and all that.

  18. What a wonderful community! So happy to be virtually friends with each of you ...

    I just wish I had the slightest clue about the mystery photos . . .

  19. Look at the 'ski' on the nose assembly! Apparently it was prone to taking a header in the dirt when landing! I am amazed anyone would even climb in to fly this thing!

  20. Well Merideth in Wyoming, you know what they say about those daring young men in their flying machines.
