BANDUNG, Indonesia --- PT Dirgantara Indonesia (PTDI) succeeded in producing unmanned aircraft, named Nir Air Crew (PUNA) type Medium Altitude Long Endurance (MALE) which is able to fly continuously for 24 hours. The plan, in 2020 PTDI will again produce two prototypes of PUNA Male.
PTDI Director Elfien Goentoro said the unmanned aircraft was the vehicle needed to maintain the sovereignty of the Unitary Republic of Indonesia (NKRI).
He explained, PTDI's unmanned aircraft was able to reach an altitude of 3,000 to 6,000 meters above sea level with cruising power reaching 30 hours without stopping.
"This unmanned aircraft will start flying next year. This is only the first prototype, there will be an advanced prototype," Elfien said in the PTDI Region, Monday (12/30).
The reason is, according to him the need for surveillance from the efficient side of the air continues to grow along with the increasing threat of border areas, both the threat of terrorism, smuggling, piracy, and theft of natural resources such as illegal logging and illegal fishing.
The initiation of the development of PUNA MALE has been started by the Ministry of Defense Balitbang since 2015 by involving the TNI, the Director General of the Ministry of Defense, BPPT, ITB, and PT Dirgantara Indonesia (Persero). Later, this pesawar will be operated by the Air Force.
He added, the design process began with preliminary design activities, basic design by making twice the wind tunnel model and the results of tests in 2016 and 2018 at BPPT, and making engineering documents and drawing in 2017 with the budget from the Ministry of Defense and BPPT.
Then, in 2017 a joint agreement was formed in the form of the Unmanned Aircraft Consortium (PTTA MALE) with members consisting of the Indonesian Ministry of Defense namely the Directorate General of Pothan and Balitbang, the Technology Assessment and Application Agency (BPPT), the Indonesian Air Force (Dislitbangau), the Institute of Technology Bandung / ITB (FTMD), BUMNs namely PT Dirgantara Indonesia (Persero) and PT Len Industri (Persero).
In 2019 the National Institute of Aviation and Space (LAPAN) entered as a member of the consortium. The year 2019 begins the manufacturing phase, which begins with the design structure process, the calculation of finite element method, making 3D drawings, and detailed 2D drawings done by BPPT engineers and supervised by PT Dirgantara Indonesia (Persero).
Then proceed with the process of making tooling, molding, molding and then fabrication with the pre-preg process with autoclave. In this year also procured Flight Control System (FCS) produced in Spain which is projected to be integrated in the first prototype of PUNA MALE which has been manufactured by PT Dirgantara Indonesia in early 2020. The integration process is carried out by BPPT engineers and PT Dirgantara Indonesia which has been get training to integrate and operate the control system.
The next two prototype units will be produced in 2020, one each for the purpose of flight testing and structural strength testing at BPPT. In the same year, the process of Military product certification will also begin and it is hoped that by the end of 2021 a type certificate will have been obtained from the Ministry of Defense's Feasibility Center (IMAA).
The activity of integrating weapons systems on the PUNA MALE prototype was carried out starting in 2020 and it was projected to have received military product type certification in 2023.
It is hoped that with this independence, PUNA MALE made in Indonesia can fill the needs of the Indonesian Air Force squadron to be able to oversee the territory of the Republic of Indonesia through air rides. In addition, activities can grow domestic industries in accordance with the mandate of Law No. 16 of 2012 concerning the Defense Industry.
To coincide with the PUNA MALE roll out event, the Head of BPPT, Hammam Riza and PTDI's Managing Director, Elfien Goentoro also signed a Memorandum of Understanding on Resource Utilization, as well as Facilities and Infrastructure.
The scope of this Memorandum of Understanding includes preparing PTDI aircraft to meet BPPT needs, developing Human Resources, utilizing facilities and infrastructure and potential provision of aircraft maintenance support, including operations.
"Hopefully all stages of the work in the process of developing the MALE Nirak Aircraft (PUNA) can run smoothly, as planned and then can be optimized for the needs of Surveillance and Target Acquisition that can be armed, with a Maximum Endurance of 30 (thirty) hours in Maximum Cruising Speed calculation is 235 km / hour, "said PTDI President Director, Elfien Goentoro.
In addition, BPPT also conveyed its needs for Aircraft with Artificial Rain configuration as outlined in the Letter of Intent (LoI), where BPPT had previously operated aircraft in order to carry out artificial rain missions, namely NC212 made by PTDI since year 1993
"Aircraft with Artificial Rain configuration for BPPT can then be deployed to handle Forest and Land Fires, and anticipate prolonged drought with Weather Modification Technology (TMC), by sprinkling salt (NaCl) on potential clouds, where these are issues that have often arisen in Indonesia lately, "added the Managing Director, Elfien Goentoro.
The signing of the LoI is a follow-up to the Memorandum of Understanding on the Utilization of Resources, as well as Facilities and Infrastructure dated 30 December 2019, which was signed by BPPT with PTDI, which will then be poured into a Sale and Purchase Contract to be signed in the near future.
Based on the release of the Bureau of Cooperation and Public Communication, Ministry of Research and Technology / BRIN and BPPT PR, here are the specifications of PUNA MALE Elang Hitam, which was launched today:
-- Length: 8.30 m
-- Wing Span: 16 m
-- Radius: 250 km (Line of Sight)
-- Ceiling: 7200 m
-- Endurance: up to 30 hours
-- Payload: 300 kg
PUNA MALE Elang Hitam will later fill the needs of the Indonesian Air Force squadron, help monitor the territory of the Republic of Indonesia through air vehicles, and support the development of the defense and security industry in Indonesia. [US]
