They really need somebody to iron out the English on their webpage, if for PR and intelligibility purposes alone. Also, is it legally acceptable for them to show images of the rockets of other companies on their website?

Further reading reveals that they're attempting to make two ultra-light rockets, the  ARION-1 (sounding rocket) and the ARION-2 (dedicated orbital picosatellite LV). There are some token words about reusability: they aim to develop a "full[y] reusable launch vehicle." The scale graphic suggests that one day in the indeterminate future they aspire to be an Arianespace competitor. Nothing too solid available on the website.

Edit: Graphics of ARION-1 and 2 are visible on the website. Big darn' fins.

Nice new development for PLD Space. They got a contract to test the engine developed by the DLR SMILE program, on their test-stand in Spain. Info here (http://actualidadaeroespacial.com/default.aspx?where=10&id=1&n=16875) and here (http://www.elmundofinanciero.com/noticia/50212/empresas/pld-space-probara-motores-de-propulsion-liquida-para-el-centro-aleman-para-aviacion-y-vuelos-espaciales-dlr.html)
Also A nice article was written by Spanish journalist Julio Miravalls about PLD Space, it can be found here (http://www.pldspace.com/blog/en/2015/12/27/the-european-little-space-x-published-at-medium-com/) and here (http://www.elmundo.es/ciencia/2015/12/24/567ae32322601d4c488b45a1.html).

The specs for Arion 1 and Arion 2 so far:
Arion1  Length 10m, Diameter 0,6m, engine Neton1 30kN LOx/RP-1. Suborbital rocket 100kg to 220km. The stage is reusable by guided parachute landing.
Arion 2: 2 or 3 stage rocket. Length 20m, Diameter 1,2m, First stage 2xSTG1 90kN, Second stage Neton1V 30kN (third stage 6kN green Hypergoolic (most likely HTP-Cathalist+RP-1). The first stage is also parashute rexoverable.
PLD Space plans a total of 18 launches per year from Spanisch launch center EL Arenosillo (Huelva, Spain), INTA. 10 Launches of Arion 2 the other 8 Arion1, for this they will constantly need three of both rockets. One in fabrication, one in refurbishment and one being prepared for a launch.
At the beginning of this year PLD Space wants to test the flight version of Neton1, they are raising 6mln euro to develop Arion1. In the article it is claimed that PLD Space has an orderbook worth of 40mln Euro already.
I wonder if the SMILE engine test program is included in this number.

Today PLD announced that they have got €1.56M funding from the Spanish government to develop a reusable liquid rocket engine via the TEPREL project  (acronym=Spanish Reusable Space Propulsion Technology for Launchers).

As per their estimate, the full development cost will need €6M, so they are almost half way there (they had some previous funding from CDTI and some private investors).

BTW, in addition to developing their rockets, they want to use El Arenosillo as their main launch facility. They say that it might be a good competitive alternate to places like Kiruna (if only for the weather!). Actually in the future they'd like to launch Arion 2 from El Hierro in the Canary Islands, but that's tricky since it is a natural reserve and the local government usually opposes any form of industry (certainly tourism is their main income source and the hotel owners have a lot of influence).

There's a lot more info in this presentation from 18 months ago (in Spanish).

Yup, I found about PLD fron Daniel Marín's blog!  :) I overlooked the other one, though, thanks.

In fact the video is a bit outdated, but Raul Torres tells the story of their project and outlines their future plans so it's still worth watching if you don't know them.

I've emailed them with a lot of questions, but still no reply, welI I guess they are too busy!
The most interesting aspect of this project is that, contrary to an all too common trend in aerospace industry, they are focused on building things from day 1 rather than PR (they've just got a powerpoint and a couple of videos). In the presentation he tells how one of the engineers of the team had to design the test stand because nothing like that had ever been built in Spain!

I think this post should also be placed here.
PLD just got spanish government contract (http://www.parabolicarc.com/2016/04/10/pld-space/). Not big but a good boost for their prospects

So PLDspace got has two contracts running. The engine test for DLR (SMILE-horizon2020) and the contract from the spanish government to continue work on their own engines.

23k euro? I'm assuming that's after tax? Otherwise that's a ludicrously low wage for a job like that, surely?
Title: Re: PLD Space
Post by: IRobot on 01/03/2017 11:14 AM
I would say that the salary is before taxes, as taxes depend on your marriage status, number of children, etc.

Engineering positions in Spain and Portugal pay really bad and there isnt much public recognition of our job. Plus, unemployment in Spain is quite large. So tens of thousands of Engineers leave for other European countries (that's why I partially moved to Germany).

Engineers from Spain have a harder time getting out, as their level of English is usually quite bad.

Very nice writeup (in Spanish) in Daniel Marin's blog, on PLD's plans and achievements.


http://danielmarin.naukas.com/2017/06/28/pld-space-dos-anos-de-pruebas-de-motores-cohete-en-espana/


Some snippets:


- Tests so far have used a calorimetric model, not machined on the outside (simple cylinder shape), for simplicity and to ease measurements. The 32-kN engine is a real-scale prototype for the Arion-1 single-stage suborbital launcher.


- Immediate plans call for the test of TEPREL-A, with a 110-s burn time, the same as the nominal first stage burn time of Arion-1.


- TEPREL-B will be the second iteration of the engine, with a 165-s burn time.


- Finally, TEPREL-C, to be tested before next year, will be the qualification version of the real Arion-1 engine.


- First (suborbital) flight of the Arion-1 is expected for NET April 2018, from El Arenosillo (Huelva, Spain). It will demonstrate a 220 km apogee trajectory for a 100 kg payload.


- Orbital launches with Arion-2 would follow in their long-term strategy after that, with first flight pencilled-in for 2021.

Spacenews article: Spain’s launch startups make a case for hosting a European spaceport (http://spacenews.com/spains-launch-startups-make-a-case-for-hosting-a-european-spaceport/)

I always tought PLD Space had it's eyes set on INTA's (CEDEA) El Arenosillo (http://www.inta.es/opencms/export/sites/default/INTA/es/quienes-somos/historia/el-arenosillo/) test Center . maps (https://www.google.nl/maps/place/Instituto+Nacional+de+T%C3%A9cnica+Aeroespacial+Centro+De+Experimentaci%C3%B3n+De+El+Arenosillo/@37.1009918,-6.7353184,2291m/data=!3m1!1e3!4m5!3m4!1s0xd11df2ec060a7f3:0x3952162e61663347!8m2!3d37.1019466!4d-6.7364243)

The Article is wrong on DLR leading the SMILE (http://small-launcher.eu/) project, its NLR (Dutch instead of German, but it's practically the same) And Smile looks to the north (http://andoyaspace.no/?p=2282) not south for a launch site.

In my opinion it is unlikely that one startup company (in Europe) will be able to develop an orbital launcher and be able to offer a service. But PLD Space has one of the best business cases in my opinion.

The company PLD Space continues with its ambitious goal of becoming the first Spanish company to build an orbital launcher. And today we have great news, because the European space agency (ESA) has chosen PLD Space as the main contractor of the LPSR (Liquid Propulsion Stage Recovery) program to develop a reusable first stage. Come on, a kind of SpaceX to the Spanish.

To put ourselves in a position, remember that PLD Space is developing two rockets, the Arion 1 and the Arion 2. The Arion 1 will be a single-stage suborbital launcher, while the Arion 2 will be able to put satellites in low Earth orbit - and even more there- thanks to its three stages. Precisely PLD Space intends to use these launchers as demonstrators of ESA's LPSR program, a program in which other Spanish companies such as COMET Engineering and Tecnalia-CTA Technology Center will also participate. The contract of the LPSR program amounts to 750,000 euros.

The objective of PLD Space is therefore to provide the Arion 2 with a reusable first stage, although previously they will carry out test flights with the Arion 1. So, does this mean that we are going to see a Spanish rocket returning to the launching pad as the Falcon? 9 from SpaceX? Not quite. Precisely the LPSR program must identify which technologies are the most suitable for the recovery and reuse of the first stages of liquid fuel rockets. In the Arion 1 reuse technologies associated with both the supersonic phase of flight and the subsonic will be tested. The techniques of reuse that will be tested in the Arion 1 will be more traditional and will consist of parachutes (both supersonic and subsonic), although the possibility of using controlled paragliders or ballutes, a mixture of parachutes and balloon that was very popular, will also be studied. in the 60s (in fact it was proposed as a braking medium for the MAR manned landing module). In addition, Arion 1 flights will test the benefits of new thermal protection systems (TPS) of the coping - remember that this suborbital launcher will reenter the atmosphere with the nose ahead - and other technologies to reduce the adverse effects of corrosion due to seawater.

The first flight of Arion 1 is scheduled for the end of 2018 and, depending on the success of this vector, the Arion 2 will follow in 2020 (obviously, no one will be shocked if there is finally some delay in these plans). A possible mission of the Arion 1 within the LPSR program could be the following: the rocket takes off from the base of El Arenosillo (Huelva) and 40 seconds later exceeds the speed of sound. About 110 seconds after the launch, the engine shuts off at an altitude of 80 kilometers and two minutes later the rocket reaches its peak at 220 kilometers. 390 seconds after the takeoff, reentry into the atmosphere would begin, which the rocket would carry out with the cap pointing towards the ground, as if it were an arrow. At 420 seconds of the mission the supersonic parachute would be deployed and at 510 seconds it would be the turn of the two larger subsonic parachutes. Finally, the landing in the Atlantic would take place 700 seconds after takeoff. Prior to this mission, a test of Arion 1 will be conducted by launching it from a military cargo plane to test the sequence of events related to the landing.

For its part, the Arion 2 will have a more advanced reuse system that will make use of the vehicle's engines. However, returning the first stage of Arion 2 to almost the launch ramp in a similar way to Falcon 9 is another matter. Why? Because this launcher is already quite small in itself and carry the necessary fuel for reuse would reduce its load capacity to practically zero. For this reason what PLD Space will do within the LPSR program is to recover the first stage of the Arion 2 using rocket engines, yes, but also parachutes, as well as nitrogen propellers and supersonic ailerons similar to those used by SpaceX on top of the first stage of the Falcon 9 (ailerons, by the way, that are used in the emergency escape system, SAS, of the Soyuz). Nitrogen thrusters and supersonic ailerons would allow to maintain control of the vehicle from the supersonic phase to landing. In the final, subsonic phase, the two motors of the first stage would be added to guarantee a vectorial control of the descent and allow to delimit the landing zone with great precision. In order to reduce the technological gap between the Arion 1 and the Arion 2 PLD Space wants to test the Arion 1.5, an improved version of the Arion 1 with two stages, the first of which will be more powerful. Although it will also be a suborbital vector, the Arion 1.5 will have a second stage that will be placed on a trajectory that simulates an orbital launch.

Although there are currently several initiatives within the ESA to create reusable launch systems, this is the first time that the European agency - and not the various space agencies of the EU countries - decides to bet on the development of technologies for recovering complete stages of liquid fuel launchers, techniques that at the moment only dominate the North American companies SpaceX and Blue Origin. And the good news is that these technologies will be tested on Spanish rockets. PLD Space now has a huge challenge ahead: to prove that not only are they capable of launching rockets, but they can also recover them. Whether they succeed or not, they will undoubtedly make history. From here we wish you all the luck of the world. I bear witness that they deserve it.]The company PLD Space continues with its ambitious goal of becoming the first Spanish company to build an orbital launcher. And today we have great news, because the European space agency (ESA) has chosen PLD Space as the main contractor of the LPSR (Liquid Propulsion Stage Recovery) program to develop a reusable first stage. Come on, a kind of SpaceX to the Spanish.

To put ourselves in a position, remember that PLD Space is developing two rockets, the Arion 1 and the Arion 2. The Arion 1 will be a single-stage suborbital launcher, while the Arion 2 will be able to put satellites in low Earth orbit - and even more there- thanks to its three stages. Precisely PLD Space intends to use these launchers as demonstrators of ESA's LPSR program, a program in which other Spanish companies such as COMET Engineering and Tecnalia-CTA Technology Center will also participate. The contract of the LPSR program amounts to 750,000 euros.

The objective of PLD Space is therefore to provide the Arion 2 with a reusable first stage, although previously they will carry out test flights with the Arion 1. So, does this mean that we are going to see a Spanish rocket returning to the launching pad as the Falcon? 9 from SpaceX? Not quite. Precisely the LPSR program must identify which technologies are the most suitable for the recovery and reuse of the first stages of liquid fuel rockets. In the Arion 1 reuse technologies associated with both the supersonic phase of flight and the subsonic will be tested. The techniques of reuse that will be tested in the Arion 1 will be more traditional and will consist of parachutes (both supersonic and subsonic), although the possibility of using controlled paragliders or ballutes, a mixture of parachutes and balloon that was very popular, will also be studied. in the 60s (in fact it was proposed as a braking medium for the MAR manned landing module). In addition, Arion 1 flights will test the benefits of new thermal protection systems (TPS) of the coping - remember that this suborbital launcher will reenter the atmosphere with the nose ahead - and other technologies to reduce the adverse effects of corrosion due to seawater.
