The Hobo Space Programme

Hobo Dave presenting his latest Rocketbob design

The Rocketbob V1

• External propulsion system consisting of 20x Sticky Bombs affixed directly to the fuselage
• Ramp launch leads to difficulty when entering the vehicle 
• Flight characteristics are violent and unpredictable
• Not enough lift generated for significant altitude gain
  

The Rocketbob V2

• Internal propulsion system consisting of 20x Sticky Bombs attached to a dynamic crate, which provides force from inside the craft.
• Launch ramp is unnecessary for flight, though it leads to a more efficient takeoff
• Flight characteristics are similar for each launch; there is an initial 'rotation' followed by a near vertical ascent.
• Lots of lift generated, however passenger comfort and saftey is an ongoing concern

Could this be a functional "Zero G" chamber?

The High Velocity Post Rocket 

• Propulsion system includes 4x external booster cylinders to help with the initial climb.
• Launch stand required for sticky bomb fuelling.
• Flight characteristics are highly stable, remaining upright even during the initial extreme vertical acceleration. 
• Reaches an altitude of 500 ft in under 10 seconds. 
• Assuming acceleration is constant, the maximum speed reached is 121.92 km/h

The Hobo Centrifuge 

• Apparatus designed for testing the limits of hobo endurance
• Ejection takes place at just under 100 RPM

Failed experiments

Not all of Dave's experiments are as successful as the RocketBob or the Post Rocket....
