The technical evaluation of the Iran -made Delta wing drone "Wide"

　On March 11, Yemen's armed organization Hushi group published a video of "strategic weapons".A large number of new weapons such as new ballistic missiles, cruise missiles, drones, mine, mortar, and infantry carrying firearms were announced, which was used to attack the Saudi Oil Facility on September 14, 2019.It contained an aircraft similar to the Delta wing (triangular wing) suicide bombing drone.This is the first time to release this aircraft from the Fushi group.

Similar points and differences with Israeli Harpy

Differences in the guidance method

　This Fushi -sang -made Iranian Delta wing drone "Wide" is very similar to "Harpy" made by Israel IAI.However, there are many different parts depending on the component configuration, and the application is completely different, so even the same self -destruction is fundamentally different weapons.

　Harpy is a wandering type that senses the radar wave that the enemy sends, and is a weapon that is close to an anti -radar missile, but the wide is the Wide (inertial navigation device) and the GPS (satellite positioning system).It is a flying program flight type and is a weapon close to cruise missiles aimed at ground -fixing goals.

　Wide has no ability to find a goal yourself, even though it is a drone, and it will be used to fly to the specified position before launch.

Difference in size

　In addition, IAI Harpie is 2 overall length.7m, full width 2.Compared to 1m, the wide Iran made is considerably larger, 4m long and 3m in width.You can see that it is not a copy weapon just by referring to the rough shape.

　The large blade antenna (two in total because there are two on the lower surface of the lower surface) that can be seen on the upper surface of the back of the harpie are not wide because they are related parts of passive trader sequence.The stick that protrudes forward from the Delta wing is an anti -speed meter (pitot tube), which is hard to see, but has a thin stick on the wide.

While the vertical tail motion wing (ladder)

　Harpy's winged tip plate is a vertical wing with a motion wing (rudder: direction rudder), and controls the yaw direction as a steering wing.On the other hand, the wide wing tip plate is just a stable wing and has no wings.( * Note that both are not wing lets for the purpose of improving fuel efficiency.)

　This is the difference between the accurate location of the enemy position, which is not known in advance, and the difference between the program that flew to a place where the location has already been known, and the latter, the latter, requires detailed mobility.Because it was not, the control system was simplified, and the wing end plate would have been a mere stable wing.

　Even if there is no ladder (direction rudder), it is possible to turn the aircraft just by tilting the aircraft by the aid wing.It is a common format in radio control airplanes and targeted drones for training, and the program -type wide is close to the target drone not only in the guidance method but also in the structural structure of the wings.

　Halpy's evolution type "Hallop 2" is a vertical wing with a motion wing ladder when checking the debris used on the battlefield.In the "JWS01 (ASN-301)" of China, which is a copy of Harpy, and the Kensho in Taiwan, you can check the vertical tail motion wing ladder mechanism at the actual aircraft exhibition at the weapon exhibition.The structure of the harpie is all a vertical tail with a motion wing ladder.

　Please note that mockups (models) for exhibition may have a broken mechanism of motion wing.

Differences in the wing of the main wing (Ellon, elevator)

　You can see that the wide announced this time has a linkage rod with a motion wing and a servo on the main wing, so it can be judged that it is an actual machine instead of a mock -up.

　There are two types of wings on the wides of the wide wings, and the inner motion wings are estimated to be elevators (rising steering) and the outer wing.

　On the other hand, the wing of Harpy's main wings is called Elevon, a method that integrates Elylon and elevator.The mechanism of the servo can be reduced, but if both functions are used at the same time, the control will be complicated because it will be a synthetic movement.Probably, Wide did not adopt an elevon to make it a simple control system even if the number of parts increased.

In common with Harpy, only Delta wings and propeller promotion

　Wide and Harpy look exactly the same shape, but only the part of the delta wing and propeller promotion.The sensor, the guidance device, and the maneuvering control are all different.Wide is not a copy of Harpy.

Differences between 2019 remaining parts and 2021 release

Difference in the shape of the wing end plate

　The published self -bombed and unmanned aircraft is equipped with a vertical wing end plate extended in both upper and lower directions, but the wing end plate of the drone debris collected during the Saudi Aramco attack in 2019 is only upwards.The shape is different.

　It is the same as Harpy that the wing end plate is only upward, but the wing end plate of the 2019 drone wreckage has no motion wing, and the harpie wing end plate has a motion wing, so this is also a different thing.。

Rotary engine → 4 -cylinder piston engine

　And the engine is also different.Harpy is a rotary engine (Vancel type), but the wide is probably an air -cooled horizontally opposed 4 -cylinder piston engine.And the debris collected in 2019 is considered to be a rotary engine from the shape of the cooling fin and the mounting direction.The engine is completely different.

2021: Air -cooled horizontally opposed to 4 -cylinder piston engine (2 stroke type)

2019: Rotary engine (Vancel type)

　In the past, Iranian Aerospace Exhibition 2014 has exhibited a horizontally opposed 4 -cylinder piston engine called "MADO MD550", which looks just like the "Limbach L550" in Germany, but the wide engine is slightly different.But the shape and size are very similar.

Difference in size

　Wide is 4m long and 3m in width (self -declaration of the Fushi school), but the drone remnant when the Saudi Aramco attack in 2019 is 190-210 cm in length and 215 cm in width (the United Nations panel reported).The same Delta wing drone is completely different in size.

* The measured value of the wreckage is almost correct because the full width of the Delta wings remains, but the overall length may not be accurate because the body part on the nose has many missing parts.The total length of the debris may actually be longer.

2019 drone debris and 2021 Wide in 2021 are different models

　The drone at the time of the Saudi Aramco attack in 2019 and the wide at the time of release in 2021 are different types of aircraft with different sizes and engines, and the same Delta wing is not an improved machine based on the same type.I guess Iran may have developed a different drone with a similar shape at the same time.

Long cruising range of 2500km or more

　The name of a wide range of 2500 km or more is a surprising thing that is comparable to the Tomahawk cruise missile.However, there may be some exaggeration.Perhaps it is a long -distance flight to secure a fuel tank inside the thick Delta wing.

　In the attack on Saudi Arabia's Abukike and the state -owned oil company Saudi Aramco in Saudi Arabia on September 14, 2019, Iran, which supports the Fushi group, fires a cruise missile and a suicide drone, and flies on a detour.It was a surprise attack from the north side of going through.Depending on where the launch point was set, the estimated flight distance at this time is around 800 km.

　On March 7, 2021, a petroleum piled terminal in Rastanura, eastern Saudi Arabia was attacked by ballistic missiles and drones.This time there is no information that it was fired from the Iranian direction, so if you attack from Yemen's Hushi -controlled area, it will be about 1200 to 1300 km in a straight line.However, cruise missiles and drones will be easily captured and shot down if they flew straight straight, so they should fly.

　The red line in this figure is a drone attack route to Rastanura, which is completely unfounded.This route that flew while bypassing is about 1800 km.If the wide can fly more than 2500 km, you should be able to fly more complex routes.

　However, since the cruising speed is about 300 to 400 km / h, it is a Delta -wing propeller promotion type drone, so if you fly 2500 km, it will take about 7 hours.If the ground radar is a detour flight aiming for a thin place, and if the enemy has been flying for too long, it will be easy to find if the enemy is in the air.

　In fact, the Saudi Arabia fighter played an active role in the Rastanula attack on March 7, 2021, and the Fushitan drone attack failed.It can be said that there is a question whether it is really useful to give a long cruising range to a slow propeller drone.
