Hai bre, asta e ca si cum ai spune ca nu-i nimic inovator in masinile cu propulsie hibrida, ca oricum electricitatea fusese deja descoperita. Pana la Chaparral nu s-a mai gandit nimeni sa aplice principiu in motorsport.

Chiar nu e intrebare capcana. Oricine in afara de noi stie ca a fost inventia lui Frank Whittle.

Stati stati.  Nu cred ca e clara treaba si nici nu vreau sa zic vreo prostie.

 

Motor cu reactie sau turbojet? In mintea mea nu-s tot aia.

 

Whittle a inventat turbojet-ul. Da' nu ala propulseaza o racheta :)

Sunt aceeasi chestie. "In 1910, in the workshop of Gianni Caproni, he designed and built an aircraft known as the Coandă-1910, which he displayed publicly at the second International Aeronautic Salon in Paris that year.[5] The plane used a 4-cylinder piston engine to power a rotary compressor which was intended to propel the craft by a combination of suction at the front and airflow out the rear instead of using a propeller.

Contemporary sources describe the Coandă-1910 as incapable of flight.[6] Years later, after others had developed jet technology, Coandă started making claims that it was a motorjet, and that it actually flew"

Ventilatoarele alea ma trimit cu gandul la Chaparral 2J, o masina de curse din anii '60, care avea un set de ventilatoare de mare putere in spate, pentru crearea unei forte de suctiune, chiar si la viteze mici. A fost victima propriei performante:

. Masina aia funtioneaza pe complet alt principiu,singura chestie ce o au in comun e ventilatorul. Daca la hovercraft ventilatorul baga aer in fusta, la masina ventilatorul scoate aer de sub masina , caut info despre "ground effect" Edited by viper05

ground effect nu implica niciun ventilator.

E cu fuste.

e cu fuste e adevarat,dar fustele ale sunt acolo cu un scop.citeste mai multe despre masina aia de f1 ,aia cu care ai pus poze sa vezi la ce era bun ventilatorul ala

Am citit demult, da-o naibii de masina. Incercam sa deviez discutia catre fuste :).

 

Prima a fost aia postata de ZyZ, cu nume ciudat, pe urma Lotus a avut succes in F1 fara vreun dispozitiv mobil montat pe masina ( au mintit ca au inventat un nou tip de diferential, aiureli d-astea :) ), Ecclestone si Murray au trisat de ciuda ce le-a fost ( cu aspiratorul ala ), fustele au fost interzise pana la urma si restul e poveste :).

 

 

Lasand fustele la o parte, imi place 911 Targa. Parca are un sarm aparte masina asta. Si o zic fara ca macar sa fiu mare fan.
