The on-site nursery is privately run by an outstanding provider and took a year to set up. Only started in Sept, for community as well as staff who get a reduced rate. Happy to discuss details - email the Principal through our website.

Agreed - we have a nursery on site... one of the best decisions we've made. Plus we give new fathers two weeks paternity instead of the usual one - supporting dads important too :)

Want to join a school with fantastic staff morale, great training and a healthy life/work balance? We're looking for an MFL teacher and a Science teacher for Sept. https://t.co/9cGEWTJOPC

Cuttlefish Single Stage to Orbit Space Plane

Description

Cuttlefish is a lifting body design, powered by two ducted turbo fans and an Estes solid rocket motor. It is designed to take off like an ordinary aircraft, fly as a normal aircraft to a given height. Cuttlefish then, makes its way into orbit powered by a rocket motor. On its return journey back to Earth, after re-entry it then re-ignites its jet engines and flies back to its base.Cuttlefish, as a model of the space plane, is controlled in two ways. It is flown by a human pilot via remote control while in the jet flight phase and while in range of the radio transmitter. During the rocket phase it is flown by its on-board auto pilot (based on a PICAXE board) with (either non mercury tilt switches or a gyro/accelerometer chip) and an SFR005 ultrasonic range finder to navigate the vehicle back into range. The system will also be capable of landing Cuttlefish unaided.Other aspects of Cuttlefish will be controlled by the PICAXE system including deploying the landing gear and automatically igniting the rocket motor. Cuttlefish's target altitude is a maximum of 2000 feet (the maximum allowed by the CAA).

Possible Cuttlefish airframe variants

 

The team realised that a smaller 'drone' version of the airframe, with simplified electronics/guidance systems, carrying a cargo of water purifiers, military ration packs, simple emergency shelters, air launched from military cargo aircraft, could carry immediate aid, by air into sites of disaster such as earthquake zones etc. to provide rapid aid to areas that cannot be easily accessed due to the disaster. 

 

 

Competitions and appearances

 

2015 entry into Big Bang Near Me Fair

 

 

Project Pipeline

 

The development of Cuttlefish is listed by prototype, below:

 

Mk I - VIII Cuttlefish

Various card and paper built designs for lifting bodies. some designs flew with varying success.

 

Mk IX Cuttlefish

First balsa built version, as a blended wing design including canards. Flew well

 

Mk X - XIII

Second, larger balsa/polystyrene versions each mark with varying control surfaces and positions. These versions of Cuttlefish are true lifting bodies and do not require stub wings or canards to fly.

 

Mk XIV

First full up weight version with rocket motor mount. Flew moderately well.

 

Mk XV Cuttlefish (current version)

Design change to a facet style lifting body, First to attempt powered flight using EDF propulsion.

 

 

 Cuttlefish requires funding to allow further development.

 

Further marks of Cuttlefish will have:

  • A larger, lightweight strengthened balsa/polystyrene fuselage.
  • On board PICAXE autopilot.
  • Gyro/accelerometer chip
  • Ultrasonic height detection.
  • EDF/Solid rocket propulsion.
  • On board rocket flight ignition and control.
  • Automatically deployable landing gear controlled by the ultrasonic system.
  • On board Wireless camera.

Estimated cost for these enhancements:

£700.00
