Abstract Key issues relating to the Supersonic Business Jet (SBJ) concept are reviewed with the intent to assess the readiness of enabling technologies and hence the concept itself. The multidisciplinary nature of aircraft design precludes an in-depth analysis of each specific aspect, which could individually be the subject of a separate discipline review, hence an overview is presented. The review looks at the market, environmental issues, with particular reference to the sonic boom phenomenon & solutions, technological issues, including prediction methods, flight testing, systems, certification and interested aerospace companies and design organisations. It is apparent that the need to reduce the sonic boom signature is vital if the vehicle is to be permitted to operate over land and hence be economically viable. It is clear that sonic boom acceptability requirements must be set if resources are to be effectively focused and designs are to converge. Despite this challenge, considerable investment is aimed at de-risking many of the enabling technologies and raising readiness levels. Many technologies are moving beyond theoretical and numerical analysis into the experimental and flight test domains. Collaboration between the civil and military sectors is increasing. Clearly, supersonic air travel is not an efficient means of personal conveyance; however, concerns for the environment are difficult to balance against the ‘value of time’ benefits offered by the SBJ concept. Air travel, of which this is a specialised form, is important to the global economy. Continued effort in the areas of human factors, customer demand and certification & requirements would be beneficial.

Abstract This work presents a method for selecting the gain parameters of a C* control law for an aircraft’s longitudinal motion. The design incorporates various handling quality requirements involving modal, time- and frequency-domain criteria that were fixed by the aircraft manufacturer. After necessary model order-reductions, the design proceeds in essentially two-steps: stability augmentation system (SAS) loop design and control augmentation system (CAS) loop design. The approach partly relies on the use of guardian maps to characterise, in each case, the set of gain parameters for which desired handling quality requirements are satisfied. The approach is applied throughout the full flight envelope of a business jet aircraft and yields satisfactory results.

Abstrak--Pesawat terbang tanpa awak (PTTA) yang dikembangkan oleh LAPAN memiliki maximum takeoff weight (MTOW) yang bervariasi. PTTA ini memiliki sistem kendali (SK) yang menjadikannya dapat terbang secara auotonomous. Salah satu sub sistem inti yang ada di dalam SK adalah flight control law (FCL), dimana pengembangannya dimulai dari tahap penentuan requirement dilanjutkan dengan tahap desain SK. Dalam desain SK, tahapan metode yang digunakan adalah software in the loop simulation, hardware in the loop simulation dan uji terbang. Untuk mengetahui apakah FCL yang dikembangkan telah memenuhi requirement awal yang didefinisikan, perlu sebuah alat yang mampu merekam parameter-parameter penting selama uji terbang, yang dinamakan dengan flight test instrumentation (FTI). Pada penelitian ini, akan dibahas mengenai requirement awal yang harus dipenuhi oleh FTI, mulai dari dimensi, berat, jumlah parameter yang direkam, serta kemampuan hardware & sensor. Tahapan selanjutnya adalah melakukan market study pemilihan hardware dengan metode pembobotan dan diakhiri dengan desain arsitektur serta wiring diagram FTI. Dari hasil penelitian yang dilakukan, diperoleh desain awal FTI yang memiliki berat total kurang dari 1.5Kg dan dimensi yang bisa dimasukkan ke dalam PTTA dengan MTOW 10Kg. FTI ini juga dilengkapi dengan baterai dan sensor yang independen, sehingga tidak tergantung dan membebani system elektronik yang terdapat pada PTTA Kata Kunci : FTI, Identifikasi Parameter, PTTA
