Helikopter pelbagai guna merupakan pesawat yang popular dalam reka bentuk pesawat untuk kategori sejenis dengannya bergantung kepada kehendak pasaran. Ia dugunakan untuk ambulan udara, operasi mencari dan menyelamat, pengambilan gambar, penggambaran filem, pengankutan udara dan pengesan kebakaran. Antara ciri- ciri utama yang menjadikan helikopter antara pesawat yang mendapat permintaan tinggi adalah kerana helikopter boleh berlepas dan mendarat secara menegak yang tidak memerlukan landasan kapal terbang tetapi hanya memerlukan ruang heli. Ia merupakan pengankutan yang ideal untuk operasi pada keadaan ruang yang amat terhad dan sesuai digunakan di kebanyakan kawasan di Malaysia terutama di kawasan pedalaman di mana tiada pengangkutan udara.

Multipurpose helicopter seems to be one of the major trends in the aircraft design for the rotorcraft categories due to the market demand. There are used for air ambulance, search and rescue operasion, take photographs, film movies, air transportation, and fire detection. The main features that makes the helicopter in high demand is it can take off and landing vertically, no need a runway but just a heliport required. They are very ideal transport for operation in very limited space and suitable to use in major place in Malaysia especially in rural area where there is no airstrip. Referring to the situation in Malaysia, there is a high potential for helicopter use demand by the government, industry and corporate sector. Therefore it is expedient to design the multipurpose helicopter that may be used to fulfill the requirements of nowadays and future, and suit the Malaysia landform and environment. The main objective of this project is to design a helicopter at the same time can handle multipurpose missions that are most needed and suitable for Malaysia condition in terms of temperature and altitude above sea level at places in Malaysia. Some method and calculation were using to achieve the objective. The first step is collecting the data about Malaysian fleet such as the types and number of helicopter, temperature and average altitude. After that, the helicopter prototyope was chosen to use the initial data to find the estimation of weight. Analysis about the performances of helicopter between the Europe condition and Malaysia condition was done and the requirement for the design heliocpter so that the objective of every production is to produce very economical cost of helicopter and at the same time very high performance of the helicopter can be achieved. As conclusion, there are many of differences performance of helicopter in Europe and Malaysia condition because it has the different temperature. Besides that, the numbers of blades also influence the performance and cost of the helicopter.
