This paper gives a detailed and step-wise procedure for design and fabrication of outdoor remotely controlled Airships. The methodology is a systematic collation of various design approaches and concepts that were examined during the ongoing design and field trial exercises related to remotely controlled airships and aerostats at the Lighter- Than-Air Systems Laboratory of IIT Bombay and finally selecting the best out of it. A methodology for arriving at the dimensions of fins from static stability conditions along with its attachment on the envelope surface is presented. The paper also focuses on shape and materials used for the envelopes of airships along with the fabrication process followed. Design, fabrication and attachment method of Gondola is also presented. Some data related to design fabrication and flight testing of a prototype of this airship is also presented.
