It’s summertime, and a young man’s fancy turns to… attaching rockets to his motorcycle! Except, in each of these cases, a middle-aged man is actually behind the project, which lends a Freudian question mark to their motives…Fritz von Opel was the grandson of Adam Opel, the founder in 1862 of the Opel bicycle and sewing machine factory, which moved into automobile production in 1899. In the 1920s, the factory adopted Fordian mass-production techniques, and sold an early ‘people’s car’, the Tree Frog (Laubfrosch), sold in any color you liked as long as it was green lacquer. By 1928 Opel had a 37.5% share of the German auto market, and was the largest exporter, which attracted investment from General Motors, who were looking for a foothold in Europe. In 1919 GM bought 80% of the company, and 100% of it in 1931. The Opel family took in $33.3Million from the sale of the factory, making them among the wealthiest families in Germany.Wealthy families tend to produce cavalier offspring, and the 1920s was a heyday of Gatsbian conspicuous consumption, with a newly created international press corps to spread their antics far and wide. And Fritz von Opel (the family gained a title in 1917 for services to Germany) was a risk-taking, dashing, and flamboyant extrovert in the finest 1920s style. With his slicked-back hair, owlish glasses, love for adventure, and access to amazing vehicles, he appeared to be a unique mix of a dashing Jazz Age playboy and Teutonic rocket scientist, which in fact describes him perfectly. Fritz leveraged the family fortune into a personal campaign of well-publicized adventures using cars, motorcycles, boats, and airplanes.In 1928 he began attaching rockets to racing cars, a special high-speed train car, an airplane, and a Neander/Opel motorcycle. The bike in question was an Opel MotoClub 500SS to which 6 solid-propellant rockets (with a thrust capacity of 66lbs combined) were attached. The rider activated the rockets with a foot pedal, after using the motorcycle’s engine to reach 75mph; Opel calculated that 220km/h (132mph) was then possible. The World Motorcycle Speed Record in 1928 was held by O.M. Baldwin on his 996cc Zenith- JAP, at 124.5mph (taken at Arpajon, France): theoretically, the World Record was within reach!On May 19, 1928, the rocket-boosted Motoclub (dubbed ‘the Monster’, for obvious reasons) was demonstrated at the Hamborner Radrennbahn, with much smoky drama, before a crowd of 7000. In early testing, it was clear six rockets didn’t give enough boost, so Opel doubled down on the concept, adding 12 rockets for the demonstration. He seriously considered an attempt at the absolute World Motorcycle Speed Record, but simply strapping on rockets isn’t a guarantee of success even in a straight line. In truth the boost was unpredictable and frightening, and the ordinary roadster motorcycle chassis, even if if was a fine specimen like the Neander design, was asking for stability issues. The German racing authorities thought so as well, and forbade the use of the rocket-cycle for a speed attempt, on the grounds of safety.Fritz von Opel attached rockets to cars: the RAK-1 and RAK-2, as well as two aircraft (also RAK-1 and 2), and a rocket train that reached 157mph, but crashed. He also raced boats in this intense period of activity, 1928 and ’29, but left Germany by 1930, spending his time in Italy, the USA (in 1940 even) and Switzerland, where he died in 1971. Fritz von Opel was the original Rocket Man.For our Road Test of a 1930 Neander (without rockets!) take a look here.
Very nice – and just to round up that story from the aeronatical point of view – it is not that clear if Fritz von Opel would have been the first to fly a rocket powered airplane. He sure financed the one of the first rocket powered flights (with a “Lippitsch-Ente(Duck)” piloted by Fritz Stamer). One of the first? Had there been other attempts? Yes!
And that flamboyant young man did not spawn from a wealthy family. He was a self-taught airplane-builder and pilot called Gottlob Espenlaub (1900-1972). He first work as a help for the chef at the international “Wasserkuppe” Meeting for Glider planes in 1919, where he met Ernst Lippitsch from whom he learned a lot. The story went on and Espenlaub became a quite well known builder and pilot (best known for his hair raising crashes and some groundbreaking technical details).
He tried rocket power in 1928 too. In 1929 he made it on the pages of the New York Times with a kind speedrecord with his second rocketplane (a flying wing).
Oh, sorry, I thought about posting some pictures…
Many thanks Rainer! I’ll investigate this too!
In the 1931 Champion comic annual, (it’s a mix of Boy’s Own-type adventure stories and factual tales of derring-do) – one of the factual features is about a bloke called Captain White who fixed a bunch of rockets to his motorcycle outfit. First run was 12 rockets and 120mph! Second run, he doubled the number of rockets, the first few went as intended, but then all the rest caught fire at once and blew up and the outfit overturned. He escaped with his life but was so shaken up he didn’t try again.
I tried Googling him but couldn’t find any mention of him. Photo can be seen on the Motorcycles 1867-1930 Facebook group.
I’ll check this out. There was an British rocket experimenter too, A.M. Low. Will post a story on him.
