Various variants of the PD-170 engine are going to be used on Turkish UAV's:
- PD222ST is 5 kg lighter and 55 horsepower more powerful than PD170
- It will be ready for mass production in 1 year
- It will contribute to the take-off of Bayraktar TB3 from LHD with strong takeoff power output
TUSAŞ Engine Industries AŞ (TEI) exhibited the PD222ST engine, which is 5 kilograms lighter and 55 horsepower more powerful than Turkey's first turbodiesel aviation engine PD170, developed to power unmanned aerial vehicles (UAVs), at the Aviation, Space and Technology Festival TEKNOFEST.
TEI General Manager and Chairman of the Board Prof. Dr. Mahmut Faruk Akşit told Anadolu Agency (AA) that the PD170 was developed for the needs of Anka-S.
Explaining that the first Anka flew with an imported 155 hp engine and there were some problems in supply, Akşit said that they started working on the PD170.
Emphasizing that Turkish engineers have developed the world's highest altitude, least fuel-consuming engine with the design and production of its technicians, so that it can operate comfortably up to 40 thousand feet, Akşit pointed out that competing products are generally designed to operate at around 25 thousand feet.
Stating that after developing the main engine structure, they started to produce derivative engines for other needs by keeping the main frame of this engine the same, Akşit gave the following information about the PD222ST, which they exhibited for the first time:
"This is how we developed the PD222ST. There will be different versions of it. ST means single turbo. Single turbo version. We got 170 horsepower with twin turbo in PD170, but the main target there was altitude power. In the future, wars will be between unmanned vehicles, maybe UAVs. It will be happening in different parts of the world. We are talking about the dogfight of UAVs. It will be more agile, agile, maneuverable, with higher power at altitude, it will be able to walk very easily behind the UAV in front of it and hit it from any position it wants. Very serious. provides an advantage.
Being a twin-turbo provided all this, but for some applications, take-off power is more important than altitude. We want to take off from our TCG Anadolu ship loaded with Bayraktar TB3s from a short runway. Take-off power is also very important here, this engine has been specially designed for high take-off power. The power was increased by 55 horsepower, we increased it from 170 to 225. It still has high altitude capability, but the power it produces at high altitude is not as much as the PD170. When you go up to 35-40 thousand feet, the power becomes less."
More than 60 PD170s produced
prof. Dr. Akşit stated that they continue the mass production of the PD170 in addition to the development studies, "The engine we produced in total exceeded 60. We delivered a significant part of it to our first main customer, TAI, we delivered a few to Baykar, some of which will be used in Bayraktar TB3 studies. "The same engine is used in Aksungur, and some of it is to be used in the C version of Akıncı. Our same engine is used in Aksungur. The numbers of serial production are increasing, and we are currently negotiating for a few 100 units." said.
Easy to switch to advanced engine
Expressing that they exhibited the first prototype of the PD222ST at TEKNOFEST, Akşit said that the engine was subjected to serious tests and maturation processes continue. Pointing out that the test period is around 100 hours, Akşit pointed out that the test times on the PD170 exceeded 5 thousand hours. Akşit said:
"We may not have to test the PD222ST that much since we're testing the base engine in these conditions, but it will undergo a more rigorous testing process. It also needs a year to go into mass production. We'll see that it flies and goes into mass production in the next year," he said. We aim to announce that which of our customers will be the first to use this engine. It is almost the same weight as the competitor engine. While the competitor engine is 155 hp, this gives 225 hp. It will provide great advantages in terms of take-off power and runway distance. It can be Bayraktar TB3 and Akıncı C, now which Baykar? I don't know if it is ahead. We are developing derivative engines to be used with the same interface as the PD170 in order to maximize the number of vehicles it is used in. Minor touch-ups are required in the integration, but an advanced engine can be installed after making its first flight in the PD170. This is Aksungur, Akıncı, Anka, Bayraktar TB3 can do."
