Sesosok putra
bangsa lahir di belahan Indonesia bagian tengah. Ialah Bacharuddin Jusuf
Habibie, sesosok makhluk cerdas yang mengharumkan nama Indonesia karena
penemuan-penemuannya dalam bidang penerbangan yang bermanfaat bagi
dunia internasional.
Ane sendiri mengagumi sosok Pak Habibie sejak duduk di bangku SD, saat gelar Pak Habibie masih Prof. Dr. Ing. ane ga tahu apa yang membuat ane mengaguminya, sepertinya senyumannya yang meneduhkan dan kecerdasannya yang sangat menakjubkan. Itulah Pak Habibie sosok yang sangat hebat dalam dunia penerbangan. Berikut ini tentang prestasi beliau:
Prestasimu membanggakanku |

Spoiler for Dornier DO-31 Specification:
In the early 1960s, the Luftwaffe became increasingly concerned that their airfields were vulnerable to air attack from Eastern Bloc forces and actively researched the possibility of dispersed operations which included flying from Autobahnen but required aircraft with STOVL capabilities. Part of these trials involved Luftwaffe F-104 Starfighters being rocket launched from stationary ramps in what became known as the ZELL program. The Starfighters were to be recovered to short strips using aircraft carrier-type arresting gear. The Do 31 was intended to use the same strips as forward operating bases.[2]
When the high cost, technical and logistical difficulties were realised the Luftwaffe ceased trials involving VTOL aircraft such as the Do 31, VJ101 and the later VFW VAK 191B which resulted in the cancellation of these projects and further use of these aircraft was limited to research purposes only.
Initial designs incorporated a Bristol Pegasus[3] vectored-thrust turbofan in each of the two inboard nacelles and four Rolls-Royce RB162 lift engines in each of the outer nacelles. It was planned to dispense with the outer nacelles and their engines when larger RB153 turbofans (of approximately 5,000 lbf (22 kN) thrust) became available. By mounting the engines in pods, the fuselage could provide a capacious hold with a rear loading ramp.
In all, three test articles were built, these being E1, E2 and E3 - the "E" indicating Experimentell (Experimental). E1 was powered only by the Pegasus engines, and was designed to test horizontal flight. E2 was a static test airframe, and did not fly. E3 had both Pegasus and RB162 lift engines installed, and was designed to test the vertical flight mode. The first prototype (E1) first flew on 10 February 1967 with just the two Pegasus engines. The third prototype (E3) flew in July 1967 with all ten engines fitted. The first hovering flight took place on 22 November 1967. Full forward and backward transitions were made in December 1967.
The Do 31 established several Fédération Aéronautique Internationale (FAI) world records during its ferry flight to the 1969 Paris Air Show. It was the first, and so far only, vertical take-off jet transport ever built. The project was cancelled in April 1970, although it made its final public flight on 4 May 1970 during the ILA in Hanover. One of the factors that led to the cancellation was the large drag and weight of the lift engine pods which reduced the useful payload and range compared to conventional transport aircraft.
