Sparrow 112 and Rex 1

Over the weekend, I and my younger brother built 2 mini-planes. I have an intent on putting light weight engines on these currently gliders. The sparrow 112 is like any other plane, it has straight wings and a tail much like a modern airliner. In the front it has a nose cone with loads of play-doh stuck on to increase it weight. The motor of the sparrow 112 will be located inside the fuselage. Its specifications are as follows.

Sparrow 112

  • Wing span: 45cm
  • Fuselage Length: 35cm
  • Fuselage Height: 5cm
  • Wing type: Straight
  • Tail stabilizer: 18cm
  • Fuselage width: 6cm
  • Tail fin height: 5cm
  • Engine: Compressed Air / none
The other mini-plane we built is Rex 1.  Rex 1 is a delta wing craft that is very light weight. It is kind of like a flying wing. The rex 1 will use ducted fans that are hidden in the fuselage section. Rex 1 also has its direction control inside the fuselage.
Rex 1
  • Wing span: 30cm
  • Fuselage Length: 15cm
  • Fuselage Height: 4cm
  • Wing type: Delta
  • Tail stabilizer: 18cm
  • Fuselage width: 4cm
  • Tail fin height: none
  • Engine: Ducted electric fan / none

Compared with sparrow 111, Rex 1 does show better performance in all areas. However, sparrow 111 is larger in size. These planes can be fitted with payloads.

OK, This is my first post on wordpress. I’m just playing around with the settings. This blog will mainly be about whats there in my “personal interests” folder. It consists of:

  • zephirumOS
  • Proto-Indo-European information
  • Simulations
  • Machine learning
  • Other mathematical intersts

Amazing blog system!! Anyway I enjoy math and science. I also like to program. I have built my own OS in assembly. 

Back to hello world.

Hello world in c++:

#include <iostream>
