Golden Age Pioneers: Juan de le Cierva

[@illefille]

I can tell you, Juan de la Cierva was a genius!

[@LordBuntaro]

Juan de la Cierva, el verdadero padre del helicoptero, el que creó la naturaleza del helicoptero (la pala de rotor de batimiento). Sikorsky se basó en los trabajos de Juan de la Cierva para crear al final el rotor de cola, lo que supuso el actual aparato que todos conocemos. Pero sin Juan de la Cierva, jamás hubiera existido el helicoptero

Thanks for this tribute to Don Juan, great video.

[@Bomberguy]

Better than you might think, here are the specs on the C.30: Performance Maximum speed: 110 mph (177 km/h) Cruise speed: 95 mph (153 km/h) Range: 285 mi (458 km) Rate of climb: 700 ft/min (213.4 m/min)

[@omepeet2006]

Cheers mate! More than 40 years ago I saw a C.30 in a museum. This is the first time I see an autogiro in action. Great!

Juan de la Cierva. Se cumplen ahora 25 años desde aquel mítico vuelo.

[@EIGYRO]

First class video. Thank you very much. Gyros aren't dead. They are the best fun you can have with your clothes on. They are like flying a motorbike.

[@Alastor73]

@fernandosilves ah y para tu informacion, decirte que la familia De la Cierva fueron siempre gente vinculada con la ingeniera, gente que son autenticos genios, como el sobrino de Juan de la Cierva, que vive todavia aqui en Murcia y ha hecho grandes inventos para Estados Unidos.

[@schlusselmensch]

Thank you for the explanation, I had imagined some sort of mechanism where the prerotation gear bore perhaps on arms on a feathering spindle, with a spring return to positive pitch. The angled lag hinge is quite an elegant solution.

gênio e mestre da aviação!!

[@Alastor73]

@Palouito vamos a ver, lo vuelvo a repetir: artilugios como el que hizo este señor mallorquin ya se habian hecho incluso algunos siglos atras, donde hubieron grandes inventores, pero Juan de la Cierva te guste o no fué el que lo hizo volar ¿o como te crees que vuela un autogiro y un helicoptero? gracias al llamado ROTOR ARTICULADO, esa es la base de que puedan volar y ese artilugio solo podia diseñarlo un ingeniero como Juan de la Cierva. Es como los aviones, antes de los hermanos Wright

[@stealhty1]

Cierva Rocks

[@Alastor73]

@Palouito se hicieron muchos diseños de aviones, unos volaron unos pocos segundos y otros no volaron, pero los que hicieron volar al primer avion fueron ellos ¿lo vas entendiendo? y lo del rotor articulado que se te quede en la cabeza que eso lo creó Juan de la Cierva, y funcionó, el aparato pudo volar.

[@drjimmysnervetonic]

Thanks Bomberguy! Best Video Yet!!!!

[@schlusselmensch]

I was speculating and did say that there were other ways to do the pitch change without a swashplate. By the way, any of his machines that didn't rely on aerodynamic surfaces for rotor control were in effect using a swashplate for cyclic control. It's just that the swashplate mechanism is hidden, or combined, with the rotor bearing/s.

[@schlusselmensch]

@Afrocanuk Tough one to answer as swashplate mechanisms were in common use long before Cierva utilized them. I suppose just as soon as he started tilting the rotor hub for cyclic control he pioneered the swashplate because in reality the swashplate and the rotor hub assembly would be one and the same. It was only when a jump takeoff feature was incorporated that the classic swashplate might have become a required feature (although there are other ways to do it). I suppose his patents would tell.

[@dajsinjo]

what a guy !!!

[@XXAVIERBAP]

The Cierva 'jump start' autogyros didn't use a swashplate. Angling the lead-lag and flap articulations by a value different from 90º made the 'autodynamic' rotor possible. With this system, and while the rotor was pre-rotated on the ground, the blades were in a extreme lag position and at zero pitch. As soon as the engine was disconnected, and the torque applied to the rotor went to zero, the blades advanced to the extreme lead position, and -thanks to the angled articulation- got the pitch...

[@XXAVIERBAP]

... got the pitch that was necessary for the rotor to pull the gyro a few meters high, for the 'jump start', while the rotor inertia lasted...

[@drjimmysnervetonic]

Does anyone know the method of construction of the rotor blades on the various models?

[@leviterande]

perfect music what is its name?

[@schlusselmensch]

There have been a few aircraft of this sort, yes.

[@jonzflicks]

Did I hear the commentator say that the propeller was only used for take off and landing? Surely that is not so.

[@sushi77]

you only need to power the front propeller the big roof porpeller is turning by the windspped!

[@imsofaman]

Bomberguy ROCKS!!!!!

[@MasterMindmars]

Existe un video donde incluso aterriza y despega de la terraza de un rascacielos en Nueva York, demostrando así que se comporta como un auténtico helicóptero. Video en blanco y negro. Supongo de los años 30.

[@spitfireJEJ]

The only war duty I know they were put to was the calibration of early radar. Very hush hush at the time of course.

[@visineish]

@Tenchu73 Claro, si yo estoy contigo.

[@spstockcar]

Has no-one ever tried a hang glider size gyrocopter?

[@DoNotPushHere]

but there are!

[@guillensuarezmartinez831]

AUTOGYRO MODEL; - 1311 C.30: 🛩️🛩️🛩️🛩️🛩️🛩️

[@Palouito]

tienes toda la razón Fernando! Yo soy de este pueblo de Llucmajor donde vivia hace años este señor, da mucha rabia porque fue engañado y siempre ha sido así! digan lo que digan! menos mal que hay alguien que sepa la verdad al cien por cien! ;)

[@hackajim]

faster than an automobile in 1895, in the air, sounds like 2010 new age george jetson technology.

[@visineish]

Amigos, el inventor fue Juan de la Cieva, la historia del Mallorquin es solo eso una historia mas, tambien se dijo que la Coca Cola se invento en Valencia y muchas otras Historias, lo del señor Mallorquin si lo hubiese inventado el estaria patentado, de verdad que ganas de engañar al personal.

[@fernandosilves]

Esta información es falsa, no fué Juan de la Cierva el inventor del autogiro. Fué un agricultor de Mallorca que envió los planos al ministro de industria, el padre de Juan de la Cierva, quien facilitó la información a su hijo y se adjudicó unos meritos que no le corresponden

[@Palouito]

gente como tú hacen que seas un farsante. PERE DE SON GALL ES EL REAL INVENTOR DEL AUTOGIRO!!!
