Guest 13snoopy Posted May 17, 2006 Report Share Posted May 17, 2006 Can anyone tell me the absolute minimum hanger door width to get a 269 through. I'd appreciate it very much. Quote Link to comment Share on other sites More sharing options...
Guest pokey Posted May 17, 2006 Report Share Posted May 17, 2006 A friend of mine gets his 300C thru an 18 foot wide door, altho the 1 skid is right up against the door jamb, and he must turn the blades to clear as it moves thru the door. Without turning the blades, the minimum would be 25 feet. I am considering building a hangar & am putting in a 30 foot wide door, for my B model, (which has almost a foot shorter blade) 23 feet would be the minimum for an A or B model.

niftyben Posted May 17, 2006 Report Share Posted May 17, 2006 I've always wondered if there were aerodynamic problems with flying your helo right into it's parking spot in the hangar (assuming the building was well wide enough). Would the containment of the air in the hangar be like super ground effect? Quote Link to comment Share on other sites More sharing options...

Would the containment of the air in the hangar be like super ground effect?Im pretty sure the down wash would be recirculated through the rotor system which causes a higher induced flow resulting in greatly reduced performance or potentialy a roll as a result of dysemetry of lift . Could be wrong though Quote Link to comment Share on other sites More sharing options...

Could be wrong though Aerodynamics aside, you wouldn't be able to keep anything in the hanger unless it was tied down. What would happen the first time you forgot about securing the trashcans, or if you left out empty oil bottles. They may just get blown to the back of the hanger, and stay there, or they could get recirculated into the main or tail rotor. Quote Link to comment Share on other sites More sharing options...
Guest pokey Posted May 17, 2006 Report Share Posted May 17, 2006 i seen 'em do it in the movies & they dont appear to have any problems. Birds fly thru tiny spaces, holes & places i woudnt take a helicopter. seriously tho, altho i never tried it? i dont think it would have much effect. read the "chicken" post in the grapevine tho,,, kinda along the same line as this question ( in my book) Quote Link to comment Share on other sites More sharing options...
HH60Pilot Posted May 28, 2006 Report Share Posted May 28, 2006 I've always wondered if there were aerodynamic problems with flying your helo right into it's parking spot in the hangar (assuming the building was well wide enough). Would the containment of the air in the hangar be like super ground effect? It would depend on the size of the hangar. If it is only large enough for the helicopter, then I think that you are going to create some problems for yourself. Not only with the aerodynamics, but ticking off those with the hangars next to you for stirring up a mess everytime you taxi in or out. Not to mention the stress to the structual integrity of the hangar (or the neighboring hangars). Just make sure that you don't wind up blowing the doors off the tracks, or cause a bifold door to sway in the breeze. IMHO, you'd be best off using ground handling wheels, or get a dolly and a tug if you are too lazy to push your bird. Doug Quote Link to comment Share on other sites More sharing options...
