Lâgari Hasan Çelebi
According to a report by Evliya Çelebi from the 17th century, Lâgari Hasan Çelebi was an Ottoman - Turkish aviation pioneer who is said to have completed a successful manned flight with a rocket .
The report
Evliya Çelebi describes the rocket as a 7 cubits long (1 cubit = approx. 64 cm) cone-shaped construction with a seven-jet ejection, which was filled with 50 okka black powder (1 okka = 1.282 kg).
According to Evliya's report, Lâgari Hasan Çelebi launched this rocket from Sarayburnu , a point below the Topkapi Palace . The flight took place at the time of the birth of Sultan Murad IV's daughter in 1633 . Before the start, Lâgari announced that he wanted to “talk to Jesus in heaven”. He took off with the rocket, glided with wings over the Bosporus and landed successfully, which earned him gold, the rank of Sipahi and a position in the Ottoman army as rewards from the Sultan .
Evliya Çelebi wrote about Lâgaris brother Hezarfen Ahmed Çelebi , who previously a one year glide to have taken over the Bosphorus.
interpretation
If one assumes, according to Evliya Çelebi's report, that the launch weight of the rocket was around 165 kg - i.e. around 1600 N weight force had to be overcome - and that around 450 to 600 grams of black powder per jet burned per second, that would have been for a burning time of 15 to 20 Seconds are sufficient to ensure a starting thrust of around 1700 N, which is necessary for a successful start.
reverberation
John Wilkins' comment on human flight in his work "A Discovery of a New World" from 1684 is related in some sources to Evliya Çelebi's description of the brothers Lâgari Hasan and Hezarfen Ahmed. This can only be questioned because the source Busbequius given by Wilkins died in 1592, i.e. before Evliya Çelebi's year of birth 1611 and the alleged flight date 1633:
"Tis not perhaps impossible, that a man may be able to fly, by the application of wings to his own body; as Angels are pictur'd, as Mercury and Dædalus are feigned, and as hath been attempted by divers, particularly by a Turk in Constantinople "
İstanbul Kanatlarımın Altında (“ Istanbul Under My Wings”) from 1996 is a film about the life of Hezarfen Ahmed Çelebi, his brother Lâgari Hasan Çelebi and about Ottoman society in the early 17th century during the reign of Murad IV Evliya Çelebi was told.
In the episode "Crash and Burn" of the TV show MythBusters , which was broadcast on November 11, 2009, attempts were made to reconstruct the rocket launch of Lâgari Hasan Çelebis. The attempt failed and the legend was classified as busted ("refuted").
